loca-
In order to determine the fault condition on an NC-machine, a fundamental knowledge of the machine and the servo amplifiers is necessary, as well as a knowledge of their interaction with the Control and measuring system. In addition, improper use of the Control, such as incorrect NC-programming or incorrect selection of machine parameters can lead to the occurrence of fault conditions. Further information in this respect can be found in the: .Wachine Documentation of the Wanufacturer -Service Manual -Handbook for the Machine Hanufacturer The handbook for the machine manufacturer is not enclosed with every control as the service manual. It is generally only supplied to the machine manufacturer and is submitted It is therefore absolutely to a “change service” by HEIDENHAIN, Traunreut. necessary to consult the machine manufacturer in the case of errors concerning the machine parameters or the interface of the control. Support can Traunreut or by HEIDENHAIN also be obtained by the HEDIENHAIN service, agencies. Telephone numbers or addresses and telex/telefax connections can be found on the inner side of the cover page and on the rear side of the service manual.

The TNC 351/355 contains a comprehensive, integrated supervision system to avoid input or operating errors, to localize and diagnose faults of technical defects of the whole plant (TNC, measuring system, machine, cabling etc.). The supervision system is a fix component of the TNC-hardware and software and is always operative when the control is switched on. The recognition of a technical defect or an operating error is displayed in plain language on the screen. Insignificant

Causes
The integrated supervision system differentiates between insignificant and significant errors. Significant errors are displayed with a flashing display (e.g. erroneous functions of linear transducers, drives and errors in data processing). The control opens the contact "Control ready" in the case of significant errors. This results in a EMERGENCY-STOPof the machine. The state “EMERGENCY-STOP” can only be eliminated again by switching off the main switch provided that the error cause was eliminated before. Flashing

The various voltages for the LE are converted in the “POWER SUPPLY Board Assembly” from the +24V- supplied (see Block Diagrams, page 27 and 28). The on/off-condition of the output voltages are displayed by LEDs. The level of the individual voltages can only coarsely be displayed by LEDs.

The POWER SUPPLY Board Assembly is protected by two fine-wire fuses. The t24V BE output voltage is protected by a F 2.5A fuse, all other output voltages by F 4.0A (see Block Diagram, pages 27 and 28). If a fault is detected (all voltages are missing) check if the LE 24V supply is present, then the two fuses. Safe and fast testing of the POWER SUPPLY Board Assembly is possible by means of the PSA LOAD UNIT. The plug connection to the boards at the POWER SUPPLY Board Assembly has to be disconnected and the PSA LOAD UNIT has to be connected in its place. Various voltages can be measured with a voltmeter at the sockets of the PSA LOAD UNIT. The measured values and tolerances can be compared with the values in the table, page 26. If the values of the measurements do not coincide with the values of the table the POWER SUPPLY Board Assembly is defective. If no PSA LOAD UNIT is available the voltages may also be measured points on the PROCESSOR Board or on the CLP PROCESSOR Board (for location of test points, see section 5.3.2).

Encoders can be interchanged with each other at the LOGIC Unit (Xl...X5 refer to section 4.3.1 LOGIC Unit Connections) which allows you to determine whether the encoders or the encoder inputs of the LOGIC Unit is defective. In conjunction with the above procedure the respective machine parameters have to be changed when interchanging encoders at the LOGIC Unit (LE).

If the input value for the machine parameters is 0 the machine parameter 253 has to be programmed with 2 and 254 with 1. - Enter machine parameters and switch on machine as usual.
If the same error message “ENCODER X DEFECTIVE” appears the error is due to the encoders or the extension cable. If the error message changed from “X” to “Y”, however, the encoder input of the LOGIC Unit is defective. If the reference pulse inhibit (connector X10) is used and if positioning should occur with exchanged encoders also the reference pulse inhibit for the respective axes must be exchanged.

The data lines and control lines of the cable between LE 351/355 and the RS-232-C/V.24-adapter block (id-no. 239 760 ..I are crossed. At connector X26 of the LE 351/355 the layout is carried out according to a DTU (Data Transmission Unit). Owing to the crossed data and control lines of the cable between LE 351/355 and RS-232-C/V.24-adapter the layout of the RS-232-C/V.24-adapter corresponds to the DTE (Data Terminal Equipment).

Voltages
Proportional to the traversing speed the control outputs an analog voltage of 0V (axis standstill) to 9V (rapid traverse). This voltage can simply be measured with the ANALOG OUTPUT TEST ADAPTER directly at the LOGIC Unit or at the connecting terminals of the servo amplifier with a voltmeter. If, however, no axis movement takes place due to a defect and if it is to be checked whether the error is due to the control or to an external unit proceed as follows: - Switch off mains switch at machine. - Connect ANALOG OUTPUT TEST ADAPTER to connector X8 (nominal value output) of the LE and connect voltmeter at the ANALOG OUTPUT TEST ADAPTER to the sockets of the defective axis. If no ANALOGOUTPUT TEST ADAPTER is available then connect voltmeter directly to the nominal value input of the servo amplifier. - Switch on main switch and control voltage. - Switch position display to LAG (trailing error). - Check or adjust the following machine parameters (note original input values when changing machine parameters and input them after checking).

The control outputs an analog voltage when turning the override potentiometer to the right and increases this voltage proportionally to the trailing error up to maximally 10V. If a voltage of 10V f 0.25V is measured with a voltmeter at the ANALOG OUTPUT TEST ADAPTER the control is in order. If, however, no voltage is measured then switch off mains switch, unplug connector X8 of the LE, remove the wire to the nominal value line at servo drive and check for short circuit. If the nominal value line is in order reconnect connector X8 to the LE (leave nominal value line at servo amplifier unconnected), switch on mains switch and repeat measurement by approaching the reference mark. If an analog voltage is measured the control is in order. If, however, no voltage is measured the analog output of the LE is probably defective. 13.2.1

Important functions are supervised with self-diagnosis by the TNC 351/355 control (electronic assemblies as microprocessors, read-only memory, read-write memory, positioning systems, encoders, etc.) If an error is determined when checking a flashing error message appears in plain dialog in the dialog display. The output “control ready” is opened when outputting this error message. This state can be cancelled by switching the main switch off if the error cause has been eliminated before. The output “Control ready” must switch off the 24 volt control voltage in the machine interface. Since this function is a very important safety feature the switch-off function of the output “Control Ready” is checked each time the machine is switched on via the input “Acknowledgement control ready”. The control has two supervision devices (CLP PROCESSORBoard and PROCESSOR Board). Both boards are checked one after another when switching the machine on. If the t24V are missing at the input “Acknowledgement control Ready” during the switch-on test routine the error message “CONTROL VOLTAGE FOR RELAY MISSING” appears. If, however, the acknowledgement is switched off too late or not at all after switching the output off the flashing error message “EMERGENCY-STOP DEFECTIVE” appears. Also if the supply is missing for the PLC-part a flashing error message “EMERGENCY-STOPDEFECTIVE” appears (Supply for the PLC-Part, see section 5.4). If an error is determined by the control during the switch-on test routine it can be determined by inserting a bridge between the output “Control ready” and the input “Acknowledgement control ready” (separate connected wires) whether the defect is due to the control or to the interface. If after inserting the bridge and correct power supply for the PLC-part the error is still present the defect is due to the LOGIC Unit. If, however, after inserting the bridge the error no longer appears the defect can be found at the interface. ATTENTION After the check it is absolutely and to regenerate the operating
necessary state.
