1. How to Use This Service Manual The service manual TNC 426.B/430.A can be used to diagnose, locate and eliminate errors on machine tools controlled by TNC. In order to correctly judge the problems in an NC-controlled machine tool, fundamental knowledge of the machine tool and its drives as well as their interaction with the control and the measuring systems is required. Incorrect behaviour of the machine tool can also result from improper use of the control, NC-programming errors and incorrect or not properly optimized machine parameters.
For further information in this respect please refer to the Documentation of the machine tool manufacturer Operating Manual (HEIDENHAIN) z Technical Manual (HEIDENHAIN). z CD-ROM TNC-GUIDE (HEIDENHAIN) z z
Note on the error description in this service manual: The number in square brackets refers to the number of the error message in the error catalogue on CD-ROM; this catalogue can be called by clicking on "NC Error Messages" in the TNC Guide.
The Technical Manual is not enclosed with every control. In general, it is only supplied to the machine tool manufacturer and is updated by HEIDENHAIN, Traunreut. Therefore, it is absolutely necessary to contact the machine tool manufacturer, if errors occur that are due to a machine parameter or to the interface of the control. Support will, however, also be provided by the HEIDENHAIN service department and agencies. Telephone numbers, addresses and telex/fax numbers can be found on the inner page of the cover page and the back side of this service manual or on our homepage under http://www.heidenhain.de.

2. Integrated Monitoring System TNC 426.B/430 features a comprehensive integral monitoring system to avoid input and operation errors, to locate errors and technical defects of the entire equipment (TNC, measuring systems, machine tool, cables etc.). The monitoring system is a fixed component of the TNC hardware and software; it is always active when the control is switched on. If a technical defect or an operation error is detected, an error message is displayed on the screen in plain language.
During operating the TNC monitors • • • • • • • • • • • •
the amplitude of the encoder signals the edge separation of the encoder signals the absolute position of encoders with distance-coded reference marks the current position (monitoring of servo lag) the path actually traversed (movement monitoring) the position deviation in standstill the nominal shaft speed the CRC sums of EPROM and RAM the supply voltage the voltage of the buffer battery the operating temperature of the logic unit the run time of the PLC program
With digital axes the TNC monitors in addition • • • • •
the motor current the motor temperature the temperature of the power module the dc-link power the supply voltage of the power stage

2.1 Log Function of TNC 426.B/430.A In the TNC 426.B/430.A a log with approx. 50 000 entries is created continuously and updated according to the FIFO principle. The last key inputs, control reset, error messages, blinking error messages with register status, defective clusters on the hard disk are entered into this log. At the moment the message *** POWER FAIL *** (see section Power supply) is not yet entered. The log is transferred via data interface with the TNCremo data transfer software (Id.No. 280 481 --, English). Starting from software version 280 472/473 the log can also be called in the control by entering the code number LOGBOOK.

Power Supply
11.1
Requirements to the external power supply
11.1.1 NC power supply (dc-link power supply) LE 426 CB, LE 430 CA: For LE 426CA an NC power supply of 140 V∼ to 450 V∼ at the terminals U1 and U2 is required. The monitoring of the supply voltage can be switched off via module 9167. To observe the European standards for electromagnetic compatibility (EN 55022), LE may only be connected to the public AC line via an isolating transformer or in connection with a line filter. Among other things these standards have to be observed to attach the CE label. If a line filter has already been installed for the supply voltage of the inverter, this voltage may also be used for the logic unit. LE 426 PB, LE 430 PA: For LE 426PA an NC power supply of 330 V∼ to 450 V∼ at the terminals U1 and U2 has to be applied. This voltage must be applied via an isolating transformer (100 VA) with basic insulation according to IEC 742 EN 50 178. To ensure the power supply of the drive control in the case of power failure, the LE must be powered with the dc-link power of the servo amplifier (385 V− to 660 V−) at the terminals +Uz and −Uz. If the dc-link power is available immediately after power-on, the supply voltage at the terminals U1 and U2 is not required. In this case a bridge must be inserted between +Uz and U1. The rectified voltage is monitored. A short-time overvoltage (approx. 5 seconds) of up to 720 V− is permissible. If the voltage exceeds 720 V−, the NC switches off the pulse enable ( 4AIAJ ) for the IGBT of the power stage. The motors run out non-controlled and no power can be fed into the dc link. If the voltage is lower than 385 V− ( *** POWER FAIL *** ) the halting procedure for all drives is controlled. The monitor of the supply voltage can be switched on and off via the module 9167. If the voltage falls below 155 V−, the control is reset; the dc-link power supply switches off at 135 V−.

Checking the NC power supply (dc-link power supply)
If an error occurs in the dc-link power supply (all voltages missing), first check the power supply line (5-pin terminal strip X31). Moreover, the supply lines of the dc-link power supply (of P-versions only) may be protected by HEIDENHAIN by means of a protective PCB (see fig. 1) The voltages may only be measured on the processor board and on the drive-control board. The test points on the respective board can be found easily. The measured values and their tolerances can be seen from the table below. If the measured values deviate distinctly from the values in the table, the power supply assembly is defective.
Danger of electrical shock! The dc-link power supply may only be opened by HEIDENHAIN service staff.
Fig. 1:
The protective PCB is equipped with 4A/500V fuses.

11.5 Buffer battery The buffer battery is the power source for the RAM when the machine is switched off. If the error message Exchange buffer battery is displayed, the batteries must be exchanged within one week. The buffer batteries are located behind a screw fitting in the power supply unit of the LE. To exchange the batteries the LE must be opened by undoing the snaps. To secure RAM data the TNC in addition to the batteries features a capacitor located on the processor board. Therefore, the line voltage may be switched off when the batteries are exchanged. Without the batteries, the charge of the capacitor is capable of maintaining the memory contents for about one day. The charge of the capacitor and the current voltage of the buffer battery can be seen in the INFO menu (see sec. 11.6).

Batteries: 3 AAA size batteries, leak-proof IEC designation: "LR6"
The capacitor is only being charged when the TNC is on. Capacitor

13. Visual Display Units 13.1 Checking the visual display unit BC 110B If the screen remains dark when the machine is switched on, first check the power supply (line voltage) of the VDU. If the voltage supply is functioning properly, a square highlighted filed can be generated on the screen of the VDU (which must be switched on) by pressing the external test button on the back side of the unit.
highlighted field test button
If the VDU generates this highlighted field, the PLC graphics board in the logic unit is probably defective. If however, the VDU remains dark after the test button has been pressed, the VDU is defective and must be exchanged. The control signals for the VDU can only be checked by means of an oscilloscope. The diagrams on the following page have been recorded with the VDU connected. The color signals R-analog, Y-analog and B-analog may differ from these diagrams (depending on the machine parameters and on the image depicted).

14.2 Speed encoder circuit Digital axes normally are operated with two encoders per axis. In most cases sealed encoders are used as position encoders. The speed encoder is a rotary encoder incorporated in the servo drive. IMPORTANT: The allocation of the axes (1st axis, 2nd axis etc.) to the axis names (X, Y, Z etc.) is defined by the machine tool builder in the machine parameter MP 100.x (see machine parameter list). This machine parameter must not be changed! The speed encoder inputs on the drive-control board of the logic unit are invariable: X15 X16 X17 X18 X19 X20 X60

Checking an Encoder
In order to give a precise statement on the electrical function of an encoder, it must be measured with a phase angle measuring unit (PWM), an oscilloscope and a leak tester (see operating instructions of encoder diagnostic set). Several adapters have been created to measure the different types of encoder signals (11µA, 1Vpp, TTL) at TNC 426.B/430.A with the PWM. You can find a connection diagram with the adapters (including Id.Nos.) in section 22.2. With the TNC 426/430 it is possible to record the analogue encoder signals of the position encoder in the internal oscilloscope with encoder: I1 (0° signal) and encoder: I2 (90° signal). The reference signal cannot be recorded! However, the signals can only be checked exactly with a phase angle measuring unit (PWM)! Irrespective of the connected encoder (1Vpp or 11µA) the signals are always displayed in mV. There is the following connection beween the signals at the encoder input and the recorded signals: Current signal 11µA:
Encoder signal at input [µA] * 284 = oscilloscope display [mV] e.g.: 11 * 284 = 3124 mV
Voltage signal 1Vpp:
Encoder signal at input [V] * 3480 = oscilloscope display [mV] e.g.: 1 * 3480 = 3480 mV

Allocation of the keys and LEDs to the PLC inputs and outputs Depending on the value entered in MP7645.0 the 12 keys on the HR 332 handwheel are assigned to different PLC inputs and the 12 LEDs to different PLC outputs. If a key is pressed, the corresponding PLC input is set. If a PLC output is set, the corresponding LED lights up. Depending on the machine parameter MP 7645.0 the handwheel HR 332 behaves as follows: If MP7645.0 = 0, the keys X, Y, Z, IV and their LEDs are assigned to NC. The remaining keys are assigned to the PLC inputs I164 to I170. The LEDs are assigned to the PLC outputs O100 to O106.
If MP7645.0 = 1, all twelve keys are assigned to the PLC inputs I160 to I171 and all LEDs to the PLC outputs O96 to O107. The handwheel symbol in the status window can be set via module 9036.

Structure of the hard disk
The hard disk of the TNC is subdivided into three partitions: TNC: PLC:
SYS:
1 500 Mbytes1) for the user's data; NC programs, tool tables, datum tables and pallet tables are stored in this partition. 64 Mbytes for manufacturer's data; this partition contains the system files, PLC programs, machine parameters, help files, PLC dialogues, PLC error tables, compensation value tables and OEM cycles. To view the PLC partition, the code number 807667 must be entered. 128 Mbytes for files related to the system (system files, NC dialogues, HEIDENHAIN cycles etc.) The SYS is not visible and cannot be selected! Caution: If you change the SYS partition, your system may not correctly work any more.
For the machine tool manufacturer the PLC partition is of major importance. We recommend to structure the directory of the PLC partition as follows: System files ∗.SYS, (MP_NAME.MP; default file) Compensation value tables ∗.CMA and ∗.COM PLC programs ∗.PLC (main program and modules) Directory for PLC dialogues and error messages (created automatically) PLC dialogues and error messages ∗.A; help files ∗.HLP PLC dialogues and error messages ∗.A; help files ∗.HLP PLC dialogues and error messages ∗.A; help files ∗.HLP PLC dialogues and error messages ∗.A; help files ∗.HLP PLC dialogues and error messages ∗.A; help files ∗.HLP Machine parameters ∗.MP NC macro Directory for OEM cycles, generated by CycleDesign generated by CycleDesign generated by CycleDesign generated by CycleDesign generated by CycleDesign Pictures for PLC soft keys

20.2.2 Checking the analogue speed nominal value interface Proportionally to the traverse speed the control outputs an analogue voltage between 0V and ±10V 1). The easiest way to determine this voltage is to measure with the TEST ADAPTER directly at the LOGIC UNIT or with a multimeter at the terminals of the servo amplifier. If however, there is no axis movement owing to a defect, proceed as described below to find out, whether the error is located inside or outside the control: • Switch off the power switch at the machine tool. • Connect the TEST ADAPTER to the connector X8 or X9 of the LE and connect a multimeter to the sockets of the defective axis. If you do not have a test adapter, connect the multimeter to the nominal value input of the servo amplifier. • Switch on power and control voltage. • Set the position display to LAG (servo lag) (see section 20.4). • Check and adjust the following machine parameters: (If you alter a machine parameter, note down the original value and re-enter it after finishing the inspection.)

• Traverse the reference points that need to be traversed before those of the defective axis. • Turn the override potentiometer of the keyboard unit completely to the left and start reference mark traverse for the defective axis. • Check the axis enable for the defective axis at the servo amplifier. • Check the screen display. * (Control ready for operation) must be ON, the F of the feed rate display must be normally lit (if the display is inverse, the feed rate enable is missing), and the symbol for "Axis not in the position loop" ) must not follow the position display. (e.g. • Turn the override potentiometer slowly to the right and turn it back left again before the servo lag display reaches the limit of the position monitoring. When the override potentiometer is turned to the right, the control outputs an analogue voltage which is increased proportionally to the servo lag up to a maximum value of 10V. The control operates correctly, if a voltage of 10V ± 0.1V can be measured at the test adapter with the multimeter. If no voltage can be measured, switch off the power switch, unplug the connector X8 or X9 from the logic unit, disconnect the nominal value line from the servo amplifier and test this line for short-circuit. If the nominal value line is in order, connect X8 or X9 to the logic unit again (leave the nominal value line disconnected), switch on the power switch and repeat the measurement with reference mark traverse. If an analogue voltage can be measured now, the control operates correctly. If no voltage can be measured, the analogue output of the logic unit is probably defective. 1)

After entering the code number, the setup menu is displayed: Select the desired position by pressing the cursor keys and then set the parameters. OUTPUT You may choose whether the nominal speed is output as a jump or as a ramp. If a ramp is output, the programmed feed rate is effective as well as the kv factors and accelerations set in the machine parameters. If you have chosen the nominal speed to be output as a jump, a jump is output as nominal speed value when the axis direction keys are pressed in the operating mode MANUAL. During the output the position loop is open. The height of the jump can be defined in the entry field for the feed rate. FEED RATE Enter the height of the step for the nominal speed (in mm/min). With "ramp" output, this entry value is of no significance.. SAMPLE TIME The sample time for recording the signals can be set between 0.6 and 6 ms. 4096 grid points are stored, i.e. the time in which the signals are stored may vary from 2.4576 to 24.576 seconds.

Selecting the operands and start of tracing Press key
Function
A table is displayed from which the operands can be selected. The control requests the positions of the table in a dialogue. Wrong inputs can be cleared by pressing DEL. It is possible to enter a trigger condition for each operand. 512 states are traced before and after a trigger event. The following trigger conditions are possible: "1"
⇒
trace if the operand is a logical "1" (trigger on positive edge)
"0"
⇒
trace if the operand is a logical "0" (trigger on negative edge)
⇒
no trigger If no trigger condition is entered for any of the operands, the operand states are traced continuously and the last 1024 states are stored.
NO ENT
e.g.: 0 I5 1 ⇒ trigger on positive edge 1 O6 0 ⇒ trigger on negative edge 2 M2003 ⇒ no trigger

21.4 Output "Control is ready" and acknowledgement for test " Control is ready " Important functions are monitored by the TNC 426.B/430.A by way of a self-diagnosis system (electronic assemblies such as micro-processor, EPROM, RAM, positioning systems, encoders etc.). For the EMERGENCY STOP routine a PLC input (X42/4) and a PLC output ("Control is ready") are available on the control. The output "Control is ready" is available several times: Logic unit, PL 405B, PL 410B,
connector X41 terminal strip X8 terminal strip X8
pin 34; maximum current consumption 100 mA pin 16; maximum current consumption 1.2 A pin 16; maximum current consumption 1.2 A
If the control detects a malfunction, it switches off the output "Control is ready"; a blinking error message is displayed and the PLC program stopped. This error message cannot be cleared by pressing CE. The error must be eliminated and then the power-on routine repeated. If the input "Control is ready" is switched off by a procedure outside the control, the error message EMERGENCY STOP is generated, and the NC sets the markers M4177 and M4178. Moreover, zero is output as nominal speed and the drives are switched off. This error message can be cleared by pressing CE after having switched off and on the control voltage. The output "Control Ready for Operation" is to switch off the +24V control voltage in the machine tool interface. Since this is an important safety function, the switch-off function of the output "Control Ready for Operation" is tested via the input "Acknowledgement control is ready" each time the control is switched on. TNC 426.B/430.A features two monitoring systems (main processor, DSP) which are also tested when the machine tool is switched on. If the +24V at the input "Acknowledgement control is ready" are missing during the test routine after power-on, the error message " RELAY EXT. DC VOLTAGE MISSING" is displayed. If however, the acknowledgement is switched off too late (or not at all) after the output has been switched off, the blinking error message "EMERGENCY STOP DEFECTIVE" is generated. If the control detects an error during the power-on test routine, a bridge can be inserted between the output "Control is ready" and the input "Acknowledgement control is ready" (disconnect the wires) in order to determine whether the defect is due to the control or to the interface. If the error is still present after inserting the bridge and with correct PLC power supply, the defect is located in the logic unit. If however, the error does not occur with the bridge being inserted, the defect is located in the interface.
*
*
Caution! Do not forget to remove the bridge and to install the standard operating state after the test.
Observe the safety instructions!

EMERGENCY STOP monitoring TNC 426/430 A PLC input (X42 / 4) and a PLC output (X41 / 34) "Control is ready" are available at the control for the EMERGENCY STOP routine. If the control detects a malfunction, it switches off the output "Control is ready"; a blinking error message is displayed and the PLC program stopped. This error message cannot be cleared by pressing CE. The error must be eliminated and then the power-on routine repeated. If the input "Control is ready" is switched off by a procedure outside the control, the error message EMERGENCY STOP is generated, and the NC sets the markers M4177 and M4178. Moreover, zero is output as nominal speed and the drives are switched off. This error message can be cleared by pressing CE after having switched off and on the control voltage. If the marker M4580 is set, an EMERGENCY STOP (input "Control is ready") is not transferred to the NC; instead the control loops of all axes and of the spindle are opened and an NC stop executed.

If an error occurs, the output "Control is ready" must generate an EMERGENCY STOP. Since this function is of great importance, the control checks this output each time when the power is switched on. The wiring recommended by HEIDENHAIN can be seen from the wiring diagram. The external electronics has to match the preset conditions. Above all make sure that "Control is ready" is acknowledged within 380 ms.

Description of controls and displays:
Err.1
If the drive does not send a STANDBY signal when the switch is in UP position (active), the DCG is not switched on and the axis cannot be moved. By setting the toggle switch to DOWN position (off), the STANDBY signal is not evaluated and the axis can be moved. If the switch is set to UP position (active) when the signal TEMPERATURE WARNING is transmitted, the DCG is not switched on and the axis cannot be moved. By setting the toggle switch to DOWN position (off), this signal is not evaluated and the axis can be moved.
Err.2
Caution: An error has occurred, if the drive does not output the STANDBY signal or the TEMPERATURE WARNING signal. If the drive is selected still, the servo amplifier may be destroyed.
Regler Ein Switch position UP (ON): Controller of DCG switched on, DCG is ready for operation. (controller on) Switch position DOWN (OFF): Controller of DCG switched off, DCG is not ready for operation. Richtung (direction)
When shifting the toggle switch the direction is inverted. The direction can only be changed, if the speed is zero.

Reset
The drive is reset, when this key button is pressed (axis stops).
Drehmoment (torque) Drehzahl (speed) Key button
Potentiometer to set the torque; left stop = off. Potentiometer to set the speed; left stop = off. When this button is pressed, the two pole terminals are connected. By means of this function e.g. an external decelerating contactor or a clamping fixture can be selected.
Vertical axes: After having changed the direction of a vertical axis, the axis may drop (speed and torque = 0). If required, select decelerating contactor or clamping fixture by means of the key button and pole terminals at the DCG.
Basic proceeding to check a PWM axis (TNC 426.B/430.A): Preparations on the machine: • Switch off the power switch of the machine tool. • Disengage the connector of the power stage of the axis to be checked from the TNC. • Connect the DCG to the servo amplifier as per the connection diagram. • Switch off the power switch of the machine tool. • In MP120/121 define the axis to be checked as counting axis. • Check the drive enable at the servo amplifier (see Basic circuit diagram of drive control). Settings at the DCG • Set toggle switches Err.1 and Err.2 to UP position (active). • Turn the potentiometers Drehmoment (torque) and Drehzahl (speed) to their left stops. • Switch on the power supply of the DCG (Netz-Ein). • Set the toggle switch Regler Ein to UP position (ON). Now, the DCG is ready for operation. Turn the potentiometers Drehmoment and Drehzahl right and back left again, until the axis moves smoothly.

23.3
Backing up hard-disk data
For a software exchange, the hard-disk data do not have to be backed up. The hard-disk data should be backed up regularly on an external data medium (PC). For this purpose HEIDENHAIN offers the data transfer software TNCBACK.EXE which is supplied with every service manual (disk in envelope). This program can also be ordered separately (Id.No. 280 534 --). With this program the entire contents of the hard disk or of individual partitions (including the subdirectories) can be read out easily in LSV2 protocol. The data can also be restored on hard disk. Please contact HEIDENHAIN, if you require this software.
1. TNC settings • Select a baud rate of 9600 or higher in the operating mode LSV2. 2. Backing-up TNC hard-disk data on an external data medium • Install the data transfer software on e.g. drive C (hard disk of personal computer). • Call TNCBACK.EXE by entering the following command line: C:\>TNCBACK (SP) (SP) (SP) (SP = space) no entry: COM1 otherwise e.g. PCOM2 for COM2 Partition to be backed up e.g. TNC: for entire TNC partition e.g. TNC:\FORM1 for a subdirectory e.g. parameter F for entire hard disk Name of the backup file (without extension!) Note: Enter C:\>TNCBACK (SP) ? to display a help text. After finishing data transfer, two files are created on the external data medium: .BCK → backup file containing the data .LST → list file to restore the backup file on the hard disk of TNC 426. 3. Restoring backed-up data on the TNC hard disk • Call TNCBACK.EXE by entering the following command line: C:\>TNCBACK (SP) (SP) R (SP) no entry: COM1 otherwise e.g. PCOM2 for COM2 Backup file on external data medium (without extension!)
NOTE: The data transfer program TNCBACK.EXE is supplied with the text file README.TXT containing a description of the functions of the data transfer software.
