6 Page 3 Issue: How to Use this Service Manual The service manual TNC 45B/425 can be used to diagnose, locate and eliminate errors on machine tools controlled by TNC. In order to correctly judge the problems in an NCcontrolled 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, NCprogramming 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) Technical Manual (HEIDENHAIN). 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 back side of the cover page and the back side of the service manual.

7 Page 4 Issue: Minor Error Messages TNC 45B/425 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 in plain language is displayed on the screen. To erase minor error messages, press CE. Further error messages are described in the Operating Manual TNC 47/45B/425 Technical Manual TNC 47/45/425 Documentation by the machine tool manufacturer Operating Instructions FE 4 B.

10 Page 7 Issue: Major Error Messages and their Causes The integrated monitoring system distinguishes between minor and gross errors. Gross errors are characterized by a blinking display (e.g. malfunctions of the encoders, of the drives and data processing errors). If a gross error occurs, the control opens the contact "Control Ready for Operation". This causes an emergency stop of the machine tool. By switching off the main switch or by pressing the error cause has been eliminated. END, the emergency stop state can be reset, provided that Display (blinking) Error Cause PROCESSOR CHECK ERROR Y = A B CRC sum control data incorrect CRC sum machine parameters incorrect Check sum NCmemory incorrect Test plane incomplete / will not run Crosstalk between data bits in RAM Crosstalk between addresses in RAM Stack overflow CRC sum PLC program ASCII CRC sum PLC program OPCode CRC sum test section Software error Wrong interrupt Differentiation with register V: 8 bus error C address error illegal instruction 4 division by 8 error output for CHK command (check range) 2 error output for TRAPV command (trap on overflow) 24 privilege infringement (supervisor command in the user mode) 28 emulator trap 2C emulator trap C interrupt vector not initialized 4 interrupt vector not initialized 44 interrupt vector not initialized 48 interrupt vector not initialized 4C C 6 false interrupt (with priority ) 647C interrupt autovector 47, user interrupt $$3FC 94BC TRAP #5 #5

NC Power Supply U 24V.5Vpp The NC part of the LE must not be connected to the control voltage of the machine tool. It requires its own external power supply generated separately according to the German standard VDE V DC voltage with a permissible AC component (ripple voltage) of.5vpp (recommended filtering capacitor µf/4v ). t..2 PLC Power Supply The PLC part (PLC inputs and outputs) of the LE, PL and PA is operated with a control voltage of 24V of the machine tool (generated according to VDE 55). The installation and connection of the measuring resistors and the analogue inputs (PL 4, PA ) must be safe from contact according to VDE 6 (section 5.5.). If this cannot be ensured, PLC and PL 4 (PA ) have to be powered according to VDE 55. Superimposed AC voltage components arising from a noncontrolled threephase bridge connection with a ripple factor of 5% (see German standard DIN 4/.75, section.2) are permissible. Thus the highest absolute value for the upper voltage limit is 32.6V; the smallest value for the lower voltage limit is 8.5V. U 32.6 V 3 V 2.4 V 8.5 V The V line of the PLC power supply must be connected to the central signal ground (line 6mm 2 ) of the machine tool. The ground connector on the PL4 housing must be connected to the protective ground (line 6mm 2 ). To avoid ground loops the measuring voltage at the analogue inputs must not be grounded. t

58 Page 55 Issue: Checking the Power Supply Unit Two lowvoltage fuses are located on the POWER SUPPLY assembly. The fuse F 2.5A protects the output voltage of +24V BE (not required for TNC 45B/425), and the fuse F 4.A protects the remaining voltages (see block diagram in section.2.). If an error occurs in the power supply (all voltages missing), first check the +24V at the supply line (2pin terminal strip 3) and then the lowvoltage fuse F 4.A. The voltages can be measured directly on the power supply board, the processor board and the CLP board (sections.3. and.3.2). The values and their tolerances can be seen from the corresponding tables. If the measured values deviate distinctly from the values in the table, the power supply assembly is defective. * Observe the safety instructions! The power supply unit does not work without load.

66 Page 6. Issue: Buffer Battery The buffer battery is the voltage source for the program memory when the machine tool is switched off. If the error message ECHANGE BUFFER BATTERY is generated, the batteries must be exchanged within one week. The buffer batteries are located behind a screw fitting in the power supply of the LE. To exchange the batteries, open the LE by undoing the snaps. In order to protect the program memory of TNC 45B/425, a capacitor (on the processor board) is used in addition to the batteries. Thus, the line voltage may be switched off during battery exchange. Without the batteries the capacitor is capable of maintaining the memory contents for about one day. 3 AAsize batteries leakproof IEC designation "LR6" * The capacitor is only being charged when the TNC is switched on.

85 Page 8 Issue: Electrical Inspection of 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) If no phase angle measuring unit is available, the electrical state of the cable, the lamp and the photocells of an encoder can be checked with an ohmmeter. The following resistances must be measured at the connector of the encoder: Possible measurements at an encoder with current interface (7 6µA) encoder connector housing against machine chassis < Ω (external shield) encoder connector housing against PIN 9 (internal shield external shield) R = encoder connector housing against PIN to PIN 8 (external shield signal lines ) R = PIN 9 against PIN to PIN 8 (internal shield signal line) R = pin against pin 2 pin 2 against pin pin 5 against pin 6 9 pin 6 against pin 5 9 pin 7 against pin 8 RP ) pin 8 against pin 7 RP ) pin 3 against pin 4 2) (switch poles of ohmmeter) (switch poles of ohmmeter) (switch poles of ohmmeter) (approx. 5 3 Ω) The measured values should approximately equal. ) If encoders with selectable reference mark are used, different resistance values can be measured (or no resistance), depending on the type of activation. 2) The encoder check (pin 3 against pin 4) can only be carried out, if the encoder light unit is a lamp. If the encoder features an amplifier section, the light unit cannot be checked at all.

Axes with Analogue Speed Controller Proportionally to the traversing speed, the control generates an analogue voltage of V to 9V (rapid traverse). The easiest way to determine this voltage is to connect the test adapter directly to the logic unit or to the connecting terminals of the servoamplifiers and to measure with a multimeter. If however, the axis does not move due to a defect, and you want to test whether the error is inside or outside the control, the following steps are recommended: Switch off the main switch at the machine tool. Connect the test adapter to the connector 8 (nominal value output) of the LE and connect a multimeter to the test adapter sockets for the defective axis. If no test adapter is available, connect a multimeter directly to the nominal value output of the servoamplifier. Switch on the main switch and the control voltage. Switch the position display to LAG (servo lag) (see section 8.3). Check and adjust the following machine parameters: (If you alter a machine parameter, note down the original value and enter it again after finishing the test.) MP Entry Value Function Original Value 4. 3 [mm] Servolag monitoring (erasable), feed forward [mm] Servolag monitoring (EMERG.

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" (e.g. ) should not follow the position display. 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.

126 Page 2 Issue: 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 V. The control operates correctly, if a voltage of V ±.V can be measured at the test adapter with the multimeter. If no voltage can be measured, switch off the main switch, unplug the connector 8 from the logic unit, disconnect the nominal value line from the servo amplifier and test this line for shortcircuit. If the nominal value line is in order, connect 8 to the logic unit again (leave the nominal value line disconnected), switch on the main 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.

136 Page 3 Issue: Trigger The following possibilities are available: FREE RUN SINGLE SHOT CHANNEL... Recording is terminated by hand. Recording of a memory contents; started by trigger condition Recording starts when the trigger threshold of the selected channel is exceeded. Trigger Threshold The trigger threshold for the selected channel is indicated as a numerical value; the units are as follows: feed rate (mm/min) position (mm) shaft speed (mm/min) servo lag (µm) analogue voltage (mv) Edges Triggering with rising (positive) and falling (negative) edge. PreTrigger Definition of recording start in % of the total recording time; possible entry values are %, 25%, 5%, 75%, %; selectable by pressing ENT Recording The recording parameters to be edited are selected via arrow keys. The values for the feed rate threshold and the trigger threshold are entered via the numerical keys. The entry values for all other recording parameters are selected by pressing ENT. Output To output a nominal value in the MANUAL mode, it is possible to chose between a preset ramp and a jump function. The jump function (only possible with digital controlled axes) is required for the adjustment of the speed encoder. Moreover, if the preliminary entry value is unknown, the maximum acceleration can be determined from jump function and recording with the oscilloscope. In MDI and AUTOMATIC the axes are always accelerated following the selected ramp. Feed Rate If a jump function is selected as output signal, the feed rate is entered in mm/min. The programmed feed rate is valid for the acceleration subsequent to the ramp. Time Resolution The recording time is between seconds and seconds (selected time x 496). The selected time (.6 ms to 6 ms) is the clock time for recording the characteristic lines. The recording time is displayed below the grating. Beginning and end of display (relative to the trigger point; cursor line T) are displayed as well.

137 Page 32 Issue: Channel to Channel 4 Four channels can be selected for recording. The assignment of the axes to the channels is variable; select the axis to be changed, press ENT to switch the channel. For each channel a characteristic line is selected. It consists of the following values: Feed rate V ACTL actual value (mm/min) V NOML nominal value (mm/min) Shaft speed N ACTL actual value (mm/min) N NOML nominal value (mm/min) Speed controller N INT difference of nominal/actual value for the speed controller (mm/min) Position S ACTL actual value (mm) S NOML nominal value(mm) Servo lag S DIFF servo lag for position controller (mm) Analogue voltage U ANALOG analogue voltage output (V) Channel OFF channel is displayed SAVED channel is stored Recording is started by pressing the START soft key. A soft key row is displayed which only contains a STOP key. The process can be interrupted at any time. During recording the stored channels cannot be displayed simultaneously, since it is not possible to synchronise the stored channels and the newly recorded channels. Evaluation of the recorded channels via cursor Whereas the entire memory contents is displayed after start, the time window selected before the start is displayed after resetup of the screen. On the left side of the screen the time T (time of trigger event) is displayed. Below there is the absolute value in [mm/min], [mm] or [mv]. If an additional cursor with the time T2 is displayed by means of the key CURSOR /2, it can be shifted with the arrow keys on the TNC operating panel. The time T2 is the difference to T; the numerical value displayed below is the difference to the value belonging to T. The T2 display and the additional cursor can be erased by pressing the soft key END or "Cursor /2". Vertical Zoom For the display of each selected channel the vertical grid can be changed in steps via soft key. The vertical grid size is displayed on the left side of the screen below the designations of the channel and the recording. Centering the Display The vertical resolution is selected such that an optimum display is ensured. Returning to the original vertical resolution: By pressing NOENT the original display of the stored data is reestablished. Horizontal Zoom The recording comprises 496 evaluated data. The time resolution (i.e. the clock time of the recorded data) can be set between.6 and 6 ms. The range for extension and compression is limited as follows: evaluated data data: pixels minimum display : max. extended display 64 : 8 The length of the displayed detail and its starting point as absolute position within the duration of the recorded data is depicted as scroll bar in the status window.

TRACE Function Activation via soft key The TRACE function provides the possibility of controlling the logic states of the markers, inputs, outputs, timers and counters; it also serves to check the contents of bytes, words and double words of the compiled PLC program. An instruction list (AWL) of the compiled program is displayed. In addition, the contents of the operand and of the accumulator is displayed in HE code or decimal code. All active commands of the instruction list are marked by "*". Use the cursor keys or the GOTO function to display the requested program part.

148 Page 43 Issue: Output "Control Ready for Operation" and Acknowledgement for Test " Control Ready for Operation " Important functions are monitored by the TNC 45B/425 by way of a selfdiagnosis system (electronic assemblies such as microprocessor, EPROM, RAM, positioning systems, encoders etc.). If an error is detected, a blinking error message in plain language is displayed in the dialogue line. As soon as this error message is generated, the control opens the output "Control Ready for Operation". The output "Control Ready for Operation" is available via: Logic unit, connector 4 pin 34 PL 4, terminal strip 3 pin PL 45, terminal strip 8 pin 6 PL 4, terminal strip 8 pin 6 By switching off the power switch or by pressing cause has been eliminated. END this state can be cancelled, provided that the error 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 switchoff function of the output "Control Ready for Operation" is tested via the input "Acknowledgement Control Ready for Operation" each time the control is switched on. TNC 45B/425 features three monitoring systems (main processor, geometry processor and CLP processor) which are also tested when the machine tool is switched on. If the +24V at the input "Acknowledgement Control Ready for Operation" are missing during the test routine after poweron, the error message " RELAY ET. 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. This error message is also displayed, if the power supply of the PLC is missing (power supply of the PLC: see section ). If the control detects an error during the poweron test routine, a bridge can be inserted between the output "Control Ready for Operation" and the input "Acknowledgement Control Ready for Operation" (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. Warning! Do not forget to remove the bridge and to install the standard operating state after the test. * Observe the safety instructions!

191 Cams for "Reference End Position": The reference marks can either be traversed manually using the axis direction keys or automatically with the start key. It is not necessary to enter a code number for the manual traverse as was the case with preceding TNC models. The traverse direction for automatic traverse of the reference marks is defined in MP32. In order to reverse the traverse direction at the end of the traverse range, a cam for "reference end position" is required. The trigger signals "ref. end position" are assigned to free PLC inputs. By the PLC software these PLC inputs are connected to the PLC markers M256 and M2556 to M Depending on the entry value of MP35 the TNC behaves differently. Linear Encoder with DistanceCoded Reference Marks (MP 35. = ), Mode If the trigger signal "ref. end position" is set when starting reference mark traverse, the axis moves in the direction opposite to that set in the MP32. If the trigger signal "ref. end position" is only set during automatic traverse, the TNC ignores this signal. Thus, there must be at least two reference marks within the range of the "reference end position". Ref. mark evaluation takes place either in the range of the "ref. end position" or else beyond this range. In case of an evaluation beyond the software limit switch range, the axis automatically moves to the software limit switch after evaluation. Linear Encoder without DistanceCoded Reference Marks (MP 35. = ) The traverse direction is automatically reversed, if the axis traverses the cam for "ref. end position". If the axis is already in the range of the "reference end position" range when starting, it moves immediately in the opposite direction. For this reason the reference mark has to be outside the "ref. end position" range. Special Operation: Linear Measurement with a Rotary Encoder (MP35. = 2) The axis automatically moves to the cam for "reference end position" at the defined feed rate (MP33). This axis is started again at a reduced feed rate (MP33) in the opposite direction; the first reference mark is evaluated after the end of the "reference end position" range has been reached. Then the axis is stopped. If the axis is already in the "reference end position" range when starting, it moves immediately at the reduced feed rate (MP33) in the direction opposite to that indicated in MP32. Linear Encoder with DistanceCoded Reference Marks (MP35. = 3), Mode 2 If the trigger signal "reference end position" is set during reference mark traverse, the axis moves opposite to the direction defined in MP32. The signal "ref. end position" is not ignored by the NC. it is only set during automatic traverse. The traverse direction is reversed immediately. Thus, no reference marks are required in the "ref. end position" range. R H. TNC 45B/425 Machine Parameters MP
