Intro G11S-LE2 is based on Fuji inverter type “G11S-EN” but with firmware including parameters specific to elevator applications. Apart from these changed parameters the inverter is the same as the “G11SEN”. For more information about hardware and other parameters look in the FRENIC 5000G11S-EN INSTRUCTION MANUAL, and in the specification for FRENIC5000G11S-LE2 sheet. This starting guide covers basic information about how to install and adjust the Fuji “G11S-4LE2” inverter (400 VAC power supply). In case you use “G11S-2LE2” inverter (230 VAC power supply), please check with Fuji Electric for differences. Section 1 covers information about how to connect and program the inverter, and a quick setup of the parameters. Section 2 contains more detailed information about the most commonly used functions. As a first introduction, it’s very useful to study the chapters regarding “timing chart open loop/closed loop” and “open loop/closed loop start up” chapters. The inverter has vector control and can be operated either in open-loop or closed-loop (with or without encoder). For closed loop operation it is necessary to install a PG-option board in the inverter. Best performance is achieved in closed loop operation.
In the parameter list each parameter has the page indicated where a detailed function explanation is given.
Please note that the values are just an example and may not match with your application.

Parameter explanation Following there is an explanation of the normally used parameters and setting examples. F00 = 1
DATA PROTECTION
0 = no protection 1 = protection With this parameter it is possible to lock the parameters so they can’t be changed from the panel. Press the STOP and while holding this also press the ARROW key to change the setting. F01 = 2 FREQUENCY COMMAND Frequency reference from the digital inputs (X1 through X9) F02 = 1
OPERATION METHOD 0 = Local control (operator panel) 1 = External RUN signals (FWD = up and REV = down)
F03 = 50 Hz MAXIMUM FREQUENCY This function sets the maximum output frequency. F04 = 50 Hz BASE FREQUENCY This function sets the maximum output frequency in the constant torque range, or the output frequency at the rated output voltage. F05 = 400 V RATED VOLTAGE (at base frequency) This function sets the rated value of the voltage output. F07 = 2.5 sec. ACCELERATION TIME Sets the acceleration time for the output frequency from startup to maximum frequency (F03) F08 = 1.8 sec. DECELERATION TIME Sets the deceleration time for the output frequency from maximum frequency (F03) to operation stop. F09 = 0 TORQUE BOOST This parameter is for V/f mode. Try from 5 to 20 depending on the application. Note: Large torque boost value might cause motor overheating. When using torque vector control mode ([F42=1]), set this parameter to 0. F20 :
DC BRAKE (STARTING FREQUENCY)
Open loop = 0.5 Hz
closed loop = 0 Hz (not used)
Defines at which frequency the DC brake has to activate. DC brake is used to stop and hold the motor before closing the brake F21 :
DC BRAKE (BRAKE LEVEL) (injection level in %)
Open loop = 80%
closed loop = 0 (not used)
Defines the braking level. The higher setting the more holding torque will be applied to the motor. Note: Large DC brake level value could cause motor to overheating.
14
F22 :
DC BRAKE (BRAKING TIME)
Open loop = 0.5 sec
Closed loop = 0.0 (inactive)
Defines the DC brake time. Set so the mechanical brake has time to close within this time. F23 :
STARTING FREQUENCY
Open loop = 0.5 Hz
Closed loop = 0.0 Hz (*)
Starting frequency. Hold the motor while the brake is being released. A small value may not avoid roll back, and a high value may produce a shock. F24 :
STARTING FREQUENCY (HOLDING TIME)
Open loop = 0.5 sec.
Closed loop = 1 sec. (*)
Holding time of the starting frequency. During this period the brake should be released. F25 :
STOP FREQUENCY
Open loop = 0.5 Hz
Closed loop = 0.1 Hz (*)
Stop frequency is related to BRKS (brake control signal). Note: The operation does not start when starting freq. [F23] is < than stop freq. [F25]. (*) Depends on controller signals. See “timing chart (closed loop)” in section 2 for more details. F26 = 10 KHz MOTOR SOUND (CARRIER FREQUENCY) This parameter sets the carrier frequency to the motor. The higher the setting the less acoustic noise from the motor. Setting possible : 0.75 to 15 kHz. (set normally to 10) F42 = 1
TORQUE VECTOR CONTROL 0 = V/f mode 1 = Activation of the torque vector control. See “auto tuning” in section 3.
E01 = 0 MULTI SPEED SS1 Setup of the first digital input as multi speed selection 1 (SS1) E02 = 1 MULTI SPEED SS2 Setup of the first digital input as multi speed selection 2 (SS2) E03 = 2 MULTI SPEED SS4 Setup of the first digital input as multi speed selection 3 (SS4) For a detailed description of the multi speed function see under section 2 “Run and speed settings” E20 = 36 CONTACTOR CONTROL Setup of transistor output Y1 as contactor control signal (CTL) Alternatively set the function “AX”(code 15) to control the contactors. In this case the signal will be on as long as the inverter is in RUN mode. For a detailed description of the contactor control see under section 2 “Contactor control” E24 = 35 BRAKE CONTROL Setup of relay output Y5 as brake control signal (BRKS) For a detailed description of the brake control see under section 2 “Brake control”

FAN STOP TIME This parameter selects the method in which the inverter cooling fan operates. 999 = Fan runs always 30 sec. to 600 sec.= Fan operation depends on the heat sink temperature and RUN signal (i.e.: if set to 300s, after RUN signal is off, and the heat sink temperature is lower of an internal set value, the fan stops in 5 minutes) H07 = 2

SECTION 2 Run and speed settings The RUN command The up and down command (RUN) to the inverter normally comes from a remote signal for elevator applications. Default for the inverter is local (control panel) so therefore a change in parameter F02 has to be made. Setting parameter F02= 1 will result in run command from the terminals FWD and REV placed in the control board of the inverter. The SPEED command The speed selection in elevator applications is normally done via digital inputs. Setting the parameter F01= 2, speed command will come from digital inputs (SS1, SS2, SS4). SS1 to SS4 can be assigned to any of the digital inputs (X1 to X9). Following the “parameter setting example”, high speed, creep speed and maintenance speed are selected through a combination of the inputs X1, X2 and X3. E01 is the parameter for selecting the function of the input X1. Set E01=0 for selecting input X1 as SS1 (Speed Selecting 1). X2 function is selected with the parameter E02. Program E02=1 for selecting input X2 as SS2. X3 function is selected with the parameter E03. Program E03=2 for selecting input X3 as SS4. In the speed selection table 1 you can see that: When X1(SS1) is activated high speed (C05) is selected. When X2 (SS2) is activated inspection speed (C06) is selected. When X1(SS1) and X3 (SS2) are activated, creep speed (C09) is selected.

Acceleration/Deceleration ramps and S-curves Acceleration/Deceleration ramps The inverter has 4 pairs of acceleration and deceleration ramps. Pair no.1 (F07 and F08) is the default one and is active if no other is chosen. To choose another pair of ramps, 1 or 2 digital inputs have to be assigned as “acceleration/deceleration selection”. When parameters E01 to E09 are assigned to code 4 or 5. X1 to X9 function is selected with the parameter E01 to E09. In the following example, input X4 and X5 have been chosen as inputs for acc./dec. ramp selection. Program E04=4 for selecting input X4 as “acceleration/deceleration selection 1”. Program E05=5 for selecting input X5 as “acceleration/deceleration selection 2”. Program desired acceleration and deceleration ramps in parameters E10 to E15. Acc/Dec. setting range is : 0.01 to 3600 s. Acc. 1 ( F07 ) Dec. 1 ( F08 ) Input 4 ( X4 ) Input 5 ( X5 )
Acc. 2 ( E10 ) Dec. 2 ( E11 ) ON
Acc. 3 ( E12 ) Dec. 3 ( E13 ) ON
Acc. 4 ( E14 ) Dec. 4 ( E15 ) ON ON
S-curves To select the S-curve function set H07 = 2 There are 4 ‘jerk’ points in total: 2 jerk points for the acceleration and 2 for the deceleration. Jerk points are determined in % (of the total acceleration or deceleration ramp) Maximum value for the jerk points is 50 % Look at the graph below for reference. It is possible to have linear curve at stop. In this case set parameter o27=1 Please, note that S-curve pattern takes longer time than linear curve. In case linear curve is selected, stopping distance is smaller (leveling distance s smaller) but less comfort is experienced in the car during acceleration and deceleration.

Speed and Acceleration/Deceleration time selection New multi speed selection table with the LE2: It is possible to save two digital inputs if next table is used. Now, each speed selected has a associated ramps (acceleration and deceleration). Speed command will come from digital inputs (SRS1, SRS2, SRS4). SRS1 to SRS4 can be assigned to any of the digital inputs (X1 to X9). E01 is the parameter for selecting the function of the input X1. Set E01=39 for selecting input X1 as SRS1 (Speed Selecting 1). X2 function is selected with the parameter E02. Program E02=40 for selecting input X2 as SRS2. X3 function is selected with the parameter E03. Program E03=41 for selecting input X3 as SRS4. In the speed selection table 2 you can see that: When NO digital input is active, speed (C05) is selected with F07 & F08 as a ramps. When only X1(SRS1) is active, speed (C06) is selected with E10 & E11 as a ramps. When only X2 (SRS2) is active, speed (C07) is selected with E12 & E13 as a ramps. When X1(SRS1) and X2 (SRS2) are activated, speed (C08) is selected with E14 & E15.

Brake control (BRKS) If you want the inverter to control the mechanical brake, relay output (Y5) or a transistor outputs (Y1 to Y4) can be selected as “brake control” signal. Program one of them with function code “35” (BRKS) Parameter for Y5 is E24 Parameters for Y1 to Y4 are E20 to E23 The BRKS ON/OFF condition is selected with parameter o19 (see table below) o19 0

Brake signal (BRKS) ON condition Brake signal (BRKS) OFF condition 1. RUN signal (FWD/REV) is set to ON 1. The output frequency reaches the stop 2. Motor torque ≥ o20 frequency (F25) (because RUN signal is set to OFF or a set Both above conditions continue during frequency which is less than the stop a period of time set in o21 frequency (F25) is activated) The above condition continues during a period of time set in o22 1. RUN signal (FWD/REV) is set to ON 2. Inverter output is active (motor current flows) Both above conditions continue during a period of time set in o21 Same as the above condition
1. RUN signal (FWD/REV) is set to ON 2. Output current is at least 0,5 times the no load current (P06)
2. Inverter output is cut off Same as the above condition
1. While the inverter is running at a higher frequency than the stop frequency (F25) and speed command set value is lower than the stop frequency (F25) 2. While the inverter is running at a higher frequency than the stop frequency (F25), RUN signal is set to OFF. One of the above conditions continues during a period of time set in o22. 3. Inverter output is cut off Same as the above condition
Both above conditions continue during a period of time set in o21
Recommendation: When using open loop, set o19 = 1 When using closed loop (encoder option), set o19 = 2 or 3
Important: If BRKS is turned OFF, it is necessary to have ON condition to activate BRKS signal again. This means that RUN signal has to be activated again. Consider this point when using BX/BBX signal or when an alarm occurs, because the inverters output (and therefore also the BRKS signal) is automatically cut OFF.

28
Contactor control (CTL) If the inverter shall control the contactors, an output has to be defined as contactor control “CTL” or RUN signal “AX”. Contactor control signal (CTL) The relay output (Y5) and the 4 transistor outputs (Y1 to Y4) can be used. Parameter for Y5 is E24 Parameters for Y1 to Y4 are E20 to E23 Program one of them with function code “36”. There are 2 parameters related to “CTL” function: o34 : contactor ON waiting time This parameter is used to ensure that the contactors are closed before the inverter starts outputting a frequency. This is a wait time between the RUN command and the starting of the inverter output. o35 : Contactor OFF delay time. This parameter is used to ensure that the inverter has stopped motor output before the contactors are opened. CTL is turned OFF when a period of time set in o35 has elapsed after the RUN command is turned OFF. When using DC brake at stopping, be sure the DC brake has finished before opening the contactors. Otherwise, arcing can occur in the contactors. Timings for the CTL signal
See more details in “timing chart (open loop) – page 31 and “timing chart (closed loop) I & II” – pages 32 & 33. RUN signal (AX) The relay output (Y5) and the 4 transistor outputs (Y1 to Y4) can be used. Parameter for Y5 is E24 Parameters for Y1 to Y4 are E20 to E23 Program one of them with function code “15”. When using RUN signal, timing for ON & OFF condition cannot be adjusted. This means that AX signal turns ON when inverter output starts, and AX signal turns OFF after DC brake. 29
Start method selection function o13 : Defines if a DC brake (0 Hz) or a starting frequency (>0 Hz) is output at start. o13 = 0 : Starting frequency (F23) is output. o13 = 1 : DC brake (0 Hz) is output. See the “specifications for FRENIC5000G11S-LE2” sheet for more details

SECTION 3 Auto tuning
There are 2 different types of auto tuning: Dynamic and static. Dynamic tuning is the most appropriated one, but requires the motor to be free (cabin should be decoupled). If it isn’t possible to decouple the cabin, tune the motor using the static tuning. In this case it is necessary manually to set manually the motor no load current (P06). Note: If encoder is used, it’s necessary to set these parameters before doing the auto tuning: o01: closed loop control Set the value 1 in this parameter to activate the closed loop control. o03: Number of encoder pulses Set the number of encoder pulses per revolution in this parameter.
Auto tuning step by step 1) First set manually the following parameters. F03 : Max. frequency. F04 : Base frequency. F05 : Motor rated voltage. P01 : number of motor poles (2: 3.000 rpm, 4: 1.500 rpm, 6: 1.000 rpm) P02 : Motor rated power (kW). See motor rating plate. (After above point, the inverter assigns automatically P03, P06,P07 and P08) P03 : Motor rated current (Amps). See motor rating plate. In case of static tuning, set manually P06 (motor no load current) - see note 1. P09: slip compensation - see note 2 how to calculate. 2) Now choose the most appropriate type of auto tuning for the lift application. In case of dynamic auto tuning set P04 to 2 In case of static (no rotating) auto tuning set P04 to 1 3) Now proceed with the auto tuning operation. Push FWD or REV button on the keypad (if local mode is activated), or active the digital input FWD or REV (if remote mode is chosen) For changing from remote mode to local mode, see chapter “Overview of the panel and button functions” in Section 1. If error “Er7” appears, it might be necessary to activate the output contactors (MC) manually. After tuning has stopped (when 3 current pulses have been heard in the motor), press the STOP button or remove FWD or REV input. 4) F42 : Torque vector control. For activation of the torque vector control mode, set F42 to 1.
41
Should a ‘P’ parameter be required to be changed manually after auto tuning, it is will be necessary to do auto tuning again (point 3). Note 1: If the motor no-load current is unknown (P06), set the value so it is between 40 and 60 % of motor rated current (P03). Note 2: To calculate the slip of the motor (P09), motor rated speed (N) has to be known. This value is normally specified on the motor plate. The synchronous speed (Ns) is: 2 poles motor: 3000 rpm 4 poles motor: 1500 rpm 6 poles motor: 1000 rpm Then use this formula to find the slip in Hz. 50 * (Ns-N) / Ns Here an example of a 2 pole motor with a rated speed of 2850 rpm. 50 * (3000-2850) / 3000 = 2,5 Hz Set parameter P09 = 2.5 If value “0.0” is selected, inverter applies standard Fuji motor slip (from an internal table).
42
UPS / Battery operation In case of power failure, a rescue operation using AC or AC + DC voltage is possible. To do so, a) a UPS (for both control and power) OR b) a UPS for control and a battery (DC voltage) for power are needed. Requirements for using the “UPS / Battery operation” function One digital input has to be programmed as BATRY function. To do so set the code “34” for one of the parameters E01 to E09 (inputs X1 to X9). Program the frequency output when activating the “UPS / Battery operation”. To do so, program another digital input as multi frequency selection (SSx) - refer to the speed selection table in page 23 or 25. Recommended frequency output values for “UPS/Battery operation” are 1.5 to 2.0 Hz. Connect the normal power supply through a contactor (in the shown example MC1). Connect the UPS through a contactor (in the shown example MC2) to the auxiliary power supply inputs of the inverter (R0-T0). If you also use a DC voltage for power, connect a battery to: R-S, R-T, S-T or R-S-T (see block diagram). In this case, connect the battery through a contactor (in the shown example MC3). Function description of the “battery function” Normally the inverter can’t operate below under voltage level. For 400 V inverters, under voltage level is 310 V. The digital input function “BATRY” cancels this detection, so operation is possible with a UPS (or UPS + Battery) in an under voltage level situation. When power failure occurs, the UPS (or UPS + battery) will supply the inverter so it can drive the machine at low speed as long as there is enough power in the UPS (or in the battery). Note: S-curve function is cancelled under battery operation. IMPORTANT : Timing for switching between normal power supply and auxiliary power When switching between normal power supply and UPS (or UPS + Battery): NEVER activate the digital input “BATRY” or connect the battery before under voltage (LU) is detected by the inverter. Safety time is 60 s approx. Otherwise, input rectifier diodes may be damaged. Following procedure should be followed: • Contactor MC1 to OFF. • After LU detection disappears, (minimum 60 seconds), switch ON MC2 and BATRY input simultaneously. For switching back to normal power supply do the above in reverse order. Battery calculation Use the following formula to define the speed according to the battery voltage. Speed command during battery operation ≤

STARTING TORQUE COMPENSATION FUNCTION Starting torque compensation Use this function to avoid the “Roll back”effect when the brake is released. The “Roll back” effect is due to that the system has a very reversible machine: i.e.: Gearless motor or geared motor with a high efficiency gear. The starting torque compensation is selected by function code o53. This function calculates the load torque from the acceleration when the brake is released, and compensates the torque output as the torque bias. If you use this function, please set the parameters included in the table below (with application values) When set frequency is 0 and operation command is turned ON, starting torque calculation begins. Parameters o50, o51 and o52 for the torque bias are effective also to this function. If o53=1, Starting torque compensation starts. Please, set the following application parameters so that this function works correctly.
C13: This value should be calculated by the following formula when the inverter rated operating frequency is f [Hz] and the elevator cage speed is v [m/min]. C13 = f / F03 * v C15: If you don’t know this value, please set 0.5 Kgm².
45
C17: See fig.1-1 Composition chat of elevator (below)
Parameters o54, o55 and o56: i.e. Fast correction (smaller accuracy)
i.e. Slow correction (bigger accuracy)
(See below)
o54 = 1 (Calculation start pulse 1) o55 = 2 (Calculation start pulse 2) o56 = 2 (Pulse count)
o54 = 4 (Calculation start pulse 1) o55 = 6 (Calculation start pulse 2) o56 = 4 (Pulse count)
If these parameters are set as above, the inverter calculates the acceleration and rotor initial movement direction using the first and the second encoder pulses. The pulse count is the number of encoder pulses the inverter is using to do the calculation. Calculation start pulse 1 (o54) 1 2 3 4 Calculation start pulse 2 (o55)

Keypad disconnected while inverter is running in local mode CPU defect card not mounted correctly check settings on option When a input set to forced stop (code 30 or 31) is going off the motor output is stopped and error Er6 activated The motor circuit was open while auto tuning was started Output contactors not activated manually An error in the communication occurred. Cause can be noise or broken wire motor running faster then output speed. Not possible to control. Torque or PI setting wrong Encoder cable broken or encoder broken Motor blocked (brake not released completely)
Speed instability (hunting) (i.e. speed demand to actual speed error)
48
Symptoms and corrections Symptom When setting P04=1 (static auto tuning) and RUN is pushed nothing happens The brake signal doesn’t activate
Possible cause Parameter P06 not set -A output signal has not been programmed to BRKS control -The time in o21 is the same or larger than the time in F24 -o46 is set to 0, and there is no encoder connected to the inverter
Inverter runs at full speed out of control. The inverter is using the encoder card OPC-G11S-PG Inverter operates in open loop even it SW1 on the encoder card is set in ON is set to closed loop position

Brake resistors and Braking Units For inverters up to 7,5 kW: Connect the braking resistor to the terminals DB and
P(+) See the connection example on page 8.
For inverters above 7,5 kW: No braking option is built in. It is necessary to connect an external braking chopper to the DC bus terminals P(+) and N(-) Connect the external braking resistor to the chopper terminals P(+) and DB. NOTE : Be sure never to connect a braking resistor directly to the inverter DC bus. See the connecting example on page 8. There is internal over-temperature protection (klixon) in the braking chopper unit. It’s necessary to program a digital input of the inverter as THR (code 9) and connect the temperature protection of the braking unit: Braking unit terminals 1 and 2 to pin P24 and THR (see “connection example” in page 8). If the braking unit becomes too hot, the over-temperature protection circuit will open and alarm “OH2” will appear.

Encoder option board & encoder set up Use this option when encoder is connected to the inverter (closed loop operation) NAME TYPE SPECIFICATION For encoders with 12–15 VDC Encoder feedback board OPC-G11S-PG power supply For encoders with 5 VDC Encoder feedback board OPC-G11S-PG2 power supply
When using the encoder option remember to select the torque vector control mode: F42 = 1 (Torque vector control is activated) Closed loop Setting o01 : Closed loop control Set value “1” in this parameter to activate the closed loop control. o03 : Number of encoder pulses Set the number of encoder pulses per rev. number in this parameter (i.e. 1024, 2048, 4096) Speed loop adjustment
Normally it is not necessary to adjust the speed loop.
But if the speed response is poor or any vibration is detected adjustment may be necessary. The best way to adjust the speed loop is by connecting an oscilloscope to the analog output of the inverter terminal FMA; to do so, program the analog output (F31) as “PG feedback amount”: F31= 8. There are 6 parameters related to the speed loop control: o28: P gain – Zero speed o29: I gain – Zero speed o30: P gain – Low speed o31: I gain – Low speed o04: P gain – High speed o05: I gain – High speed
52
Procedure: Run the elevator and look at the response on the oscilloscope. Increase P gain (o04) until the speed output becomes unstable (vibration). Set P gain (o04) a little lower to get a stable situation again. Now decrease the value I gain (o05) until the output signal becomes unstable (vibration detected). Set I gain (o05) a little higher to get a stable situation again. Adjust P gain (o28) and I gain (o29) parameters values to get zero movement at zero speed only if Starting Torque Compensation is calculated. If the speed response is poor or you get vibrations at low speeds, you can adjust the Low speed gain parameters P gain (o30) and I gain (o31) without modifying the High speed gain parameters values (o04 and o05). Please, modify the Switching frequency parameters o32 and o33 to decide the frequency in which the inverter will change from Low speed gains to High speed gains.

In this case the speed response is too slow. Improve speed response by increasing the value of o04 or decreasing the value of o05
In this case the speed response is too fast. Improve speed response by decreasing the value of o04 or increasing the value of o05
53
Speed deviation error o44 and o45: These parameters define the allowed speed difference between commanded speed and actual speed (feedback) before speed error is active (PG error). o44 : Speed detection width (% of commanded speed) o45 : Detection timer. o46 : Encoder abnormality function (defines what shall happen when speed deviation error is detected) When the relation between the commanded speed and the actual speed is ≥ o44, and this state continues during a period of time ≥ o45, inverter may trip (PG error) depending on o46: o46=0: No trip (no PG error) Continue but with a warning o46=1: Inverter trips and motor coast to stop (display “PG”)
WARNING: 1. When using the OPC-G11S-PG and no encoder is connected, the inverter will run at full speed without control and with no error. 2. The switch SW1 on the encoder optional card has to be in OFF position. Otherwise the inverter will not detect the encoder pulses and will operate in open loop control.
