1. How to use this Service Manual
The service manual TNC 306/360 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, to the .Operating
Manual (HEIDENHAIN) and to the .Technical Manual (HEIDENHAIN).
The manual for the machine tool manufacturer is not enclosed with every control as is the
operating manual. 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 service department
of HEIDENHAIN, Traunreut, and HEIDENHAIN agencies. Telephone numbers, addresses
and telex/telefax numbers can be found on the back side of the cover page and on the back
side of this service manual.

2. Minor Error Messages
The TNC 306/360 features a comprehensive integrated monitoring system to avoid input or
operation errors, to locate errors and technical defects of the entire equimpent (TNC,
measuring system, 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.

Further error messages are described in the Operating Manual TNC 306 and TNC
360, in the Technical Manual, in the Documentation by the machine tool
manufacturer or in the Operating Instructions FE 401 B.

2.1 Causes of Minor Error Messages
OPERATING PARAMETERS ERASED
- With new and exchange controls, the machine parameters are always erased.
- Software replaced with different version (see section. 15.1)
- Buffer batteries and accumulator defective
- RAM error on PROCESSOR board
LIMIT SWITCH <AXIS>
- "Manual" operating mode:
The pre-determined software limit switch or the additional limit in the auxiliary
operating modes has been reached during traverse with the direction keys.
- "Automatic" operating mode:
The calculated position of the current block is beyond the software limit switch
range or beyond the additional limit. No positioning takes place.

3. Major Error Messages and their Causes
The integrated monitoring system distinguishes between minor and major errors; major
error messages (e.g. malfunctions of the encoders, of the drives or data processing errors)
blink. In the case of gross errors, the control opens the contact "Control Ready for
Operation" which causes an emergency stop of the machine tool.

Error Cause
Position Monitoring (Servo Lag)
- Operation with feed pre-control:
position monitoring range exceeded (range defined
in machine parameter 1420)
- Operation with servo lag:
servo lag monitoring range exceeded (defined in
machine parameter 1720)
Monitoring of the Analog Voltage Limit
- The nominal voltage calculated by the control has
reached its limit of ± 10 V (only with feed precontrol).
Movement Monitoring
- The voltage difference calculated by the control has
reached the limit programmed in the machine parameter 1140.
Standstill Monitoring
- The deviation from the nominal position of an axis in
standstill has exceeded the value programmed in
machine parameter 1110.
- The nominal position was moved beyond during
positioning (overshooting).
Monitoring of Offset Voltage
- The offset voltage of 100 mV has been reached during
an automatic offset adjustment with machine parameter
1220. (see section 16.5)
GROSS POSITIONING ERROR

Central Drive Monitoring
- An error in the configuration of the central drive has been

simultaneously).
Possible location of the error, when the error message
"GROSS POSITIONING ERROR <AXIS> A/B/C/D/E/F" is generated:
When this error message is generated, the error may be located in any element of the
closed loop.
e.g. - Control error (e.g. CLP board)
- Excessive offset voltage at the servo amplifier
- Monitoring function of the servo amplifier has responded
(e.g. power monitoring)
- Servo amplifier defective
- Motor, tachometer, encoder or cables defective
- Mechanical defect (bearings, spindle, guides)
- Excessive mechanical forces on a drive
