SERVICE MANUAL TNC 415B/425 Page 3 Issue: 20.08.95 1. How to Use this Service Manual The service manual TNC 415B/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 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.

SERVICE MANUAL TNC 415B/425 Page 4 Issue: 20.08.95 2. Minor Error Messages TNC 415B/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.

SERVICE MANUAL TNC 415B/425 Page 7 Issue: 20.08.95 3. 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.

The fuse F 2.5A protects the output voltage of +24V BE (not required for TNC 415B/425), and the fuse F 4.0A protects the remaining voltages (see block diagram in section 10.2.1). If an error occurs in the power supply (all voltages missing), first check the +24V at the supply line (2-pin terminal strip X31) and then the low-voltage fuse F 4.0A.

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 MP1320. 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.
