ThyssenKrupp Aufzugswerke Operating Manual Parameters - General

Parameters

1.1

General The program enables parameter changes in a defined memory section. The permitted number range of each parameter is monitored during input and limited accordingly. A distinction is made between changeable parameters (e.g. maximum speed, direction of rotation or control device parameters) and the display parameters that show various operating values (e.g. current speed, current reference value, etc.). When the MFC 20 frequency inverter is put into operation, the following display appears:

Lift Equip MFC 20 - 105 V5.x This display of the program version number appears for only 15 seconds. In the event of any queries to the plant, specify this program version number. If one of the buttons is operated during the 15 seconds, the display of the version number is cancelled immediately and the selected function is executed. If you wait for the 15 seconds to elapse, the first available parameter is displayed.

P 0 reference value start delay 500 ms The operating time of the display lighting is set to 2 hours after the last button was pressed. The first time a button pressed after the lighting has switched off switches the lighting on again, but this has no effect on the parameter function. The contrast can be set using the potentiometer.

ThyssenKrupp Aufzugswerke Operating Manual Parameters - Operation

In the first line is the parameter number with a brief description of the selected parameter; the second line contains the current value with its physical unit. A cursor appears under the parameter number. The ”+” and ”-” buttons can now be used to select the desired parameter number. Moving the cursor with the ”Cursor” button enables selection in steps of ten or a hundred.

P 5 P gain 8.0 Pressing the ”Parameter” button moves the cursor to the numerical value and the number value can be changed.

P 5 P gain 8.1 There is an underscore beneath the lowest-value position of the numerical value. This underscore marks that position which is changed by +1 when the ”+” button is operated and changed by -1 when the ”-” button is operated. Operating the ”Cursor” button moves this marking one position to the left. This enables a rapid change to the parameter across a broad number range. If the ”+” or ”-” button is pressed for longer than 2 seconds, the parameter value is changed in a 0.25 second cycle by +1 or -1. Some parameters, e.g. P 7 - language, do not have a number as value, rather a list selection.

Here, too, the entry can be changed using the ”+” and ”-” buttons. Danger The change to the parameter values only takes effect when the change is confirmed by pressing the "Parameters" button!

P 100 motor speed + 103.5 rpm The displayed value, in this case the reference speed, is continuously updated. 1.2.3

Saving the changed parameters in the EPROM

Note Without saving the data, the parameter changes are lost when the MFC 20 device is switched off!

After the ”Save” button is pressed, the following display appears:

Save values? (+) = yes, (-) = no

Note If the ”Save” button was operated inadvertently, the save operation can be cancelled using the ”-” button (No). The ”+” button (Yes) saves all the parameters in the EPROM.

During saving, the following display appears:

Saving data ... Please wait ... During the save operation, the control voltage must not be switched off. If this does occur, all parameters are to be checked and, if necessary, corrected.

ThyssenKrupp Aufzugswerke Operating Manual Parameters - Operation

1.2.4

All parameters to factory settings This function can be used to recover the original values of all parameters at any time. If the ”Parameters” button and ”Save” button are pressed simultaneously, the following prompt appears on the display:

Load original value? (+) = yes, (-) = no If the function was started inadvertently, the operation can be cancelled using the ”-” button (No). If the ”+” (Yes) button is operated, all the parameters are returned to the factory values. Note However, these preprogrammed factory values have not yet been saved. This means that after switching the MFC 20 frequency inverter off and on again without prior saving (1.2.3 Saving the changed parameters in the EPROM, page 1-4), the old values take effect once again.

If all parameters are in their original state, the following display appears:

! Original values have ! ! not been saved yet ! 1.2.5

Individual parameters on the factory settings If a parameter is to be set to the factory value, the parameter must be displayed as described in chapter 1.2.1, Displaying and changing the parameters, page 1-2. After operating the ”Parameters” button (to change the value), if the ”+” and ”-” buttons are pressed simultaneously, the factor value appears in the display. Other parameters are not changed here.

Parameters The parameters are subdivided into: Changeable parameters (see chapter 1.4.1 Changeable parameters, page 1-8) that can change the characteristics of the device. Display parameters (see chapter 1.4.2 Display parameters, page 1-28) that indicate the various operating modes. Note Depending on the software version, not all parameters are always present.

1.4.1

Changeable parameters P 0: reference value start delay time tSTS In the case of elevators without brake acknowledgement, the delay time between activation of the brake and release of the drive can be set here. This means the reference value is only started when the brake is opened. Values between 50 and 5000 ms can be set. The typical value lies between 300 ms and 800 ms. In the case of installations with brake acknowledgement, this value must be set to 5000 ms. This means that the reference value start is dependent on the brake acknowledgement.

ThyssenKrupp Aufzugswerke Operating Manual Parameters - Parameters

P 1: brake application time (brake off time) tBE Setting of the delay time between electrical deactivation of the brake by EBS and mechanical ”gripping” of the brake. Once this period has elapsed, the frequency inverter is shut down electrically (control device interlock). Values between 50 and 5000 ms can be set. P 3: direction of rotation The direction of rotation of the motor can be changed with this parameter. The parameter can only be set to "not inverted" or ”inverted”.

P

3 direction of rotation not inverted

Changing this parameter leads to an immediately change in the direction of rotation. P 4: control direction a) Asynchronous motor For the speed controller, it is important that the polarities of the speed reference values and speed list values are correct in relation to one another. If this is not the case, the motor rotates non-controlled at low speed. Parameter P 4 can reverse the control direction. The parameter can only be set to "not inverted" or ”inverted”. Changing this parameter has the same effect as swapping two phases of the motor line. b) Synchronous motor This parameter is not present on the MFC 21/31 (synchronous motors). In the case of synchronous motors, the motor connections U, V, W must be connected is exactly the right way, as otherwise the assignment to the encoder and to the location of the magnets (poles) is not correct, i.e. the control direction cannot be reversed by swapping 2 phases. P 5: speed controller P gain The speed control characteristics of the drives can be set here (setting values 0 .. 64.6) P 6: speed controller I gain Same as P5, but for the I proportion (setting values 0 ... 9999). The lowest effective value is 4 ms. If the I proportion is to be disabled, 0 ms must be entered.

P 21: acceleration pre-control on/off If the drive tends to overshoot or undershoot, the travel quality can be improved by enabling the acceleration pre-control. This applies above all to gearless drives. P 22: acceleration pre-control gain To assess the right setting of the acceleration pre-control, the actual speed value (P 10 to ”0”) should be measured at measuring point 42A and the n-controller output (P 11 to ”7”) should be measured at measuring point 43A. Note P 21 = "Off" (pre-control off)

ThyssenKrupp Aufzugswerke Operating Manual Parameters - Parameters

Parameter for speed setting •

The selection of one of the five “main speeds” is made at the inputs at connector X1 of the TIC printed circuit board.



With simultaneous selection of vi or v0 and another main speed, the following applies: the inspection speed vi is dominant, i.e. as soon as vi is selected, the other speeds are ignored. the levelling speed v0 can always be selected; it only takes effect if no other speed remains active.



With a currently selected speed, monitoring of the reference-actual value variance is carried out ("tolerance band monitoring"). If this deviation is too great, an emergency stop is initiated.



At inspection speed Vi and emergency operation speed V3, however, an emergency stop is only initiated if the amount of the actual value is greater than 130% of the target value in each case.



For all travel curve sections (acceleration, deceleration, lower and upper roundings), the same acceleration and jerk value applies.



The stopping distance from withdrawal of the levelling speed v0 to "Electrical Halt" (speed zero) depends only on the value v0 and the set jerk value of the running characteristic curve. The parameter of this stopping distance cannot be set separately. Example: v0 = 0.1 m/s, jerk = 0.8 m/s³ -> stopping distance: 35 mm.



The short run function is only possible for the rated speed vrated.



The levelling speed v0 is typically selected as 0.1 m/s; with lower values of v0, the "levelling duration" can become very high.

Safety instructions

A) Qualified personnel Work on the MFC 20 frequency inverters may only be carried out by trained persons. These persons must comply with the relevant accident prevention regulations and be aware of the dangers of electrical current.

B) Work on the frequency inverter To work on the frequency inverter (except for setting up procedures using the operating keyboard) or the motor, the following measures are required: •

shut down



secure against reactivation



determine that there is no voltage

C) Determining there is no voltage Particular attention is to be paid to the fact that even after the mains voltage has been switched off there can still be electrical energy in the device (capacitor charge). This applies in particular in the case of a defective device. For this reason, a check for residual voltage must be carried out before starting any work on the frequency inverter. To check for residual voltage, a suitable multimeter (at least 800 V direct current) can be used to directly measure the intermediate circuit voltage at terminal block X1, terminals 22 and 23. •

Commissioning - Notes on operation

Note Set the measuring instrument to the direct current range (DC)! Work on an opened device with applied intermediate circuit voltage (approx. 700 V DC) is only to be performed in exceptional cases and only with the greatest caution. Here, particular attention is to be paid to the fact that the intermediate circuit voltage has a fixed potential relationship to the mains voltage and to the protective earth.

2.2

Notes on operation

Note The frequency inverters contain components that are subject to electrostatic risks. Before performing service work on the frequency inverters (e.g. replacement of printed circuit boards), the service personnel must eliminate static charges by touching an earthed metallic surface.

Warning In the event of incorrect assignment of the frequency inverter to the motor, the frequency inverter or the motor can be damaged. Frequently cyclical switching on and off of the frequency inverter can lead to an overload of the internal charging resistors. This is to avoided by allowing the corresponding breaks.

2.3

2-2

Notes: before switching on for the first time



Check the wiring to the frequency inverter and to the motor (including incremental encoder)



Check the electromagnetic compatibility of the earthing of the cable screens



Check of the correct protective earthing of all assemblies (frequency inverter, motor, housing and brake resistor)



Check of the mains voltage



The brake must operable and correctly set



If necessary, lead the elevator car with a half load (load compensation)

Commissioning - Check of the functional capability of the drives

2.6

Check of the functional capability of the drives

Specify the inspection speed vi in upward or downward direction. The drive must move in the corresponding direction with the desired inspection speed. If the drive moves at the right speed but in the wrong direction, use parameter P 3 "direction of rotation" to invert the direction. If the drive is not smooth or does not move at the right speed, a) for asynchronous motors use parameter P 4 "control direction" to invert the control direction. b) for synchronous motors perform an encoder adjustment (see P 86). If the inspection speed is not reached despite changing the control direction, check whether the incremental encoder is correctly inserted and/or the number of encoder marks is correct, see chapter 1.4.2 , page 1-28.

2.7

Optimisation of the drive A) Speed controller The parameters P 5 "speed controller P gain" (default value 8) and P 6 "speed controller I gain" (default value 50 ms) are available to optimise the speed actual value running characteristic curve. Perform this optimisation step by step. If necessary, set the ”I gain” right down to ”0” and the ”P gain” until the drive runs without any tendency to rock. Note It should be borne in mind that with the ”I gain" setting equal to "0” a sustained deviation in the actual speed occurs depending on the load direction, i.e. under certain circumstances the drive cannot accelerate in the load direction or even drifts in the wrong direction. The ”P gain” should have a safety clearance to the above tendency to rock (approx. factor 2 smaller). For normal operation, an ”I gain” not equal to ”0” is to be set again.

ThyssenKrupp Aufzugswerke Operating Manual Commissioning - Optimisation of the drive

Experience has shown that the given default values (P = 8 and I = 50 ms for asynchronous and P = 2 and I = 70 ms for synchronous) already result in very good travel quality. To assess the running characteristic curve, a recorder can be connected to MP 42A or MP 43A of the TMI printed circuit board. The common reference point is MP 26 or the housing of the frequency inverter. The selection of the measurement signals available at these display outputs is made using the parameters P 10 or P 11, see chapter 1 Parameters, page 1-1. Example: with the value "0" in P 10, the speed actual value with prefix is displayed at MP 42A. For minimizing reverse rotation on opening the brake at start, a higher P proportion (P 205) and a "faster" J proportion (P 206) can be specified. B) Run at rated speed To optimise the rated travel, the acceleration and acceleration change (jerk) can be changed with the parameters P 19 and P 20. Note Important here is that, in accordance with the selected acceleration, a minimum jerk is to be set (see chapter 2.8.2 Diagram for determining the minimum jerkpage 2-8), as otherwise there is no range of constant acceleration.

Important here is that the floor-to-floor distance is greater than the total of the acceleration and deceleration distance from rated speed (see chapter 2.8.3 Diagram for determining the minimum permitted floor-to-floor distances, page 2-9). In the case of floor-to-floor runs, this achieves the rated speed. C) Short run A short run is when the floor-to-floor distance is less than the total of the acceleration and deceleration distance from rated speed, but greater than the deceleration distance from rated speed. In the case of floor-to-floor runs, this does not achieve the rated speed. Procedure for activation of the short run (see chapter 3 Short run device, page 3-1).

D) Load specification If the elevator car moves away after opening the brake, this can be reduced by specifying an initial torque, see chapter 1.1 General, Changeable parameters, page 1-1, P 50 to P 54. If the load measurement device LMS 1 is used, the optimal initial torque can be specified. If there is no load measurement, the start can also be optimised for a certain load state. E) Acceleration pre-control If the drive tends to overshoot, this can be optimised by activating the acceleration pre-control, see chapter 1.1 General, Changeable parameters, page 1-1, P 21 and P 22.

Short run device

3.1

General A short run is when the floor-to-floor distance is shorter than the total of the acceleration and deceleration distance for rated speed. In the case of these runs, this does not achieve the rated speed. To reach the stop, the elevator would have to move at levelling speed for a longer period of time. The built-in short run device detects this state and automatically extends the acceleration phase of the run. This means that no creepage or only very short creepage occurs (switching delay or rope slip). Note For the short run device to function properly, the elevator specifications must be correctly set. These are: •

P 13

gear ratio



P 14

diameter of traction sheave



P 15

suspension



P 19

jerk



P 20

acceleration



P 23

speed v0



P 25

speed vN

These parameters are used to calculate the deceleration distance from vN and display it in parameter P 111. For each normal run (vN is reached), the deceleration distance is measured and displayed in P 112. This measured distance, however, is not taken into account in the short run computing. A special form of the short run is the short run with "sharper rounding" (see figure 3 3). This is the case when the deceleration point is reached during the upper rounding of the acceleration phase. If the deceleration takes place with the set jerk, the deceleration distance is too great. The landing is overrun. To avoid this, the elevator is run with a "sharper rounding", i.e. with greater jerk.

A diagram appears at the corresponding measuring point, indicating the individual phases of the running characteristic curve (siehe Abbildung 3 2).

Modernisation

4.1

General This frequency inverter (MFC 20 or MFC 30) can also be used in the case of modernisation of elevator systems with non-ThyssenKrupp motors. These motors can be single-speed or pole changing. Vector regulation is also used here. The maximum recommended speed is 1.6 m/s. The rest of this description provides the necessary information for the modernisation.

4.2

Modernisation with encoder mounting on motor shaft The regulation of "traditional" elevator motors with a frequency inverter provides the following advantages: •

Energy reduction by up to 50% (this is not a promised value, as the energy reduction depends on many influences, e.g. the type of installation, amount of runs, etc.).



No 300-Hz ripple as in the case of operation with 3-phase AC controller



No modulation noise in the motor as in the case of frequency inverters with lower clock frequency.

To ensure that configuration for the modernisation is as easy as possible, the following specifications have been made: •

Operation of single-speed or pole changing motors as well as frequency inverter motors or standard motors is possible



Motors should have class of insulation F; a converter output choke is used to reduce the coil stress



The flywheel mass should be reduced to a maximum of 1/3 of the original value or removed completely. If the flywheel mass cannot be reduced, for example in the case of external-rotor motors, the acceleration value of the installation is to be selected in such a way that the maximum output current of the converter is adequate.



If possible, the encoder must be torsion-proof and mounted on the centre of the motor shaft. The encoder must deliver push-pull TTL signals with 5 V supply voltage. The assembly is to be designed, e.g., in the same way as the Wachendorff pulse generators with part number 00 990 14 030.



The minimum landing-to-landing distance is control-dependent; with an "internal" converter running characteristic curve, the minimum landing-to-landing distances apply, see chapter 2.8.3, Diagram for determining the minimum permitted floor-to-floor distances, page 2-9.

Settings for motor adaptation To set the frequency inverter for an unknown motor, a corresponding procedure is required; under certain circumstances, an iterative process is necessary. The starting point for this is the type plate data. Here, it should be borne in mind that this is no always complete or, in the case of old elevator motors, it does not represent the rated operating point for the frequency inverter, as the ratio of maximum current to rated current was limited to certain values. This normally leads to excessively high no-load current for the frequency inverter. The table at the end of this chapter provides an aid to orientation. To enable the following parameters, "non-ThyssenKrupp motor" must be selected in P 40. a) Run automatic current controller optimisation (auto tuning P 80). b) The parameters P 60 (“motor rated frequency”), P 61 (“motor rated voltage”), P 62 (“motor rated speed”), P 63 (“rated motor current”) and P 64 (“motor cos (phi)”) are used to calculate the values for P 65 (“rotor time constant TR”) and P 66 (“no-load current Id”). Typically, the values for P 65 are between 40 ms and 400 ms; the values for P 66 are typically between 6 Aeff and 30 Aeff (depending on the motor output).

d) These default settings provide a certain basic setting for the motor. The elevator is to be balanced out, where possible, so that only the no-load current flows (load current < 5% of the maximum current) at constant speed (e.g. electrical recall). If this is the case, a travel at rated speed should be carried out. Here, a tolerance band fault can occur on acceleration; if necessary, disable this monitoring or otherwise set a lower acceleration value. The actual motor voltage value appears in the top right of parameter P 68 (and also P 67). This value should be around 270 to 300 V at rated travel. If this is not the case, the motor voltage can be reduced by lowering the value of P 68 (no-load current Id) (usually, the motor voltage that sets in with the no-load current from the type data will be too high). The motor voltage should be around 270 to 300 V in UP and DOWN direction. If there is not sufficient torque for the acceleration phase, the rotor time constant TR in P 67 must be increased or reduced. Here, the value can be changed in steps of 25%. e) The elevator is now to be operated with the elevator car empty, followed by a motor run under load in the DOWN direction and a braking run in the UP direction. In the DOWN direction, the motor voltage should rise by approximately the slip value of the motor, i.e. approx. 30 V to 50 V; in the UP direction, the motor voltage should fall by a lower value (approx. 10 V to 30 V). If this is not the case, the value of the rotor time constant TR in P 67 must be changed in steps of 25%. This setting should be made with the motor warm (not with a very cold or very hot motor). f) The setting of the speed controller is also to be checked: The I proportion of the speed controller is to be set to 0 and the P proportion is to be increased until rocking or humming of the motor occurs. The P proportion is then to be cut by half. The I proportion is to be selected in the range from approx. 10 ms to 100 ms, depending on the overshoot in the running characteristic curve. The pre-control of the speed controller with the help of the acceleration pre-control (P 21 and P 22) additionally improves the travel quality. The running performance is to be tested with no load, half load and full load.

DCP interface

5.1

Preface To activate the DCP interface, , < DCP03> or < DCP04> must be selected in P 8. DCP03 and DCP04 are serial data bus protocols that connect the converter to the elevator control system. The RS485 interface (connection X90) is used. The protocol was specified by the company Kollmorgen. Detailed information on the protocol specification can be obtained from Kollmorgen Steuerungstechnik GmbH, Cologne. Email: [email protected] From the converter side, DCP04 is currently configured for a maximum running speed of 6 m/s. If greater speeds are required, consult the manufacturer. If greater speeds are required, consult the manufacturer.

5.1.1

Installation The RS485 interface of the converter must be connected to the control system. Connector X90 is to be used, with the assignment 1=signal B, 2=signal A, 3=reference earth RS485. It is recommended to use a twisted, shielded line. Where possible, the control cabinet of the control system should be plane-connected, e.g. connected by a copper band with the housing of the converter. In this case, it is recommended to apply the screening of the DCP connection to both sides of the housing. On MFC 20 devices, the converter must be notified when the travel contactors have energised. Unfortunately, the contactor acknowledgement is not integrated in the DCP telegram traffic. For this reason, the signal must be wired in the same way as for conventional activation (input QSP1, terminal X1-10b). On MFC 30... devices, the travel contactors and contactor acknowledgements are already integrated. So that the elevator control system can perform its monitoring tasks in accordance with EN81, the relay output ("contactor control" terminal X1-4a, 5a) is available.

Note Special runs according to the DCP03 specification are also possible in the DCP4 operation mode, which is why values must also be entered for the other speeds (bit G5, G4, G0).

The nomenclature for the individual speeds has developed at the various manufacturers of elevator components independently, which means there are differences. This has resulted in a considerable risk of confusion. MFC frequency converter DCP03 / 04 documentation Kollmorgen No.

DCP04 parameters

Limit values designated with "auto" are fixed automatically by the program depending on other parameter entries. P 72 enables a certain partial distance to be run at constant speed on each run. Consequently, a lower speed is run on short runs. This slightly reduces the energy consumption and wear. The downside is that the running time increases slightly. A maximum of 1/3 of the run distance is run at constant speed, even if a longer distance is entered here. On long run distances, this setting has no effect, as a partial distance at constant speed occurs anyway. P 73 enables forcing a defined distance at creeping speed on approaching a landing instead of the direct approach. As long as the exact transformation ratios are unknown on commissioning, it is recommended to enter a higher value here. This distance already contains the deceleration distance from V0 creeping speed to zero. If zero mm is entered here, the smallest possible is set automatically. If the elevator has a tendency to run too far at the destination landing, a greater value must be entered here. P 74 see 5.1.5 Stopping accuracy with DCP04 operation, page 5-4.

DCP interface - Preface

P 75 stop position controller gain The running characteristic curve is calculated from the set parameters for speed, acceleration and jerk during almost the entire run distance and passed onto the speed controller. During the last millimetres before reaching the stop position, this strategy changes. A position controller uses the distance to the exact stop position to determine the reference values for the speed controller in such a way that the elevator comes to a standstill at virtually exactly the position specified by the DCP control system. The gain of this controller is set using P75. If an unpleasant jerk is noticeable on stopping, first set the creep distance (P 73) to a higher value, e.g. 50…100mm. Then P75 can be set in such a way that stopping is soft and pleasant. Once a setting has been found that leads to both good stopping accuracy and soft stopping, P 73 can be reset to a low value. 5.1.4

Safety function TIMEOUT control If no valid DCP telegram arrives at the converter for longer than 150 ms, the converter executes an emergency stop if the elevator is currently running. The event and fault stack of the converter then contains the entry: "DCP fault" and the number of DCP telegrams with incorrect checksum received since switching on. Furthermore, the corresponding status of the operating hour meter appears for each stack entry. Emergency stop means: block impulses, open travel contactors and close mechanical brake.

5.1.5

Stopping accuracy with DCP04 operation With DCP04 operation, particular care is required when entering the gear ratio, suspension ratio and diameter of traction sheave. Even minor inaccuracies in the diameter of traction sheave lead to inadequate stopping accuracy. The running speed on the display of the control system compared with the display of the converter, parameter P 101 "actual speed" must match during the run. If the exact diameter of traction sheave is unknown, the converter offers a mathematically determined diameter after each run on P 74 "traction sheave calculated". This is calculated from the travel information of the control system and the encoder information of the drive. However, the calculation result is falsified by rope slip and rounding errors. In order to obtain a meaningful result, a number of runs must be executed over a number of floors. The might be that P 74 shows zero mm if runs from or to the lowest landing are executed. Then, simply execute runs between two other landings and then read off P 74. If the same or almost the same value has been read a number of times on P 74, this can then be entered at P 14 "traction sheave". As a general principle, the drive tends to run too fast and too far if the input value at P 14 "traction sheave" is too low. If the input value is too high, the drive tends towards a slow approach path and slow running speed.
