4 Error messages

4.1 Introduction

Type of

error message

The iTNC 530 features a comprehensive integral monitoring system for the prevention of input or operation errors, as well as for identification and diagnosis of technical defects on the control

and the connected devices. The monitoring system is an integral component of the iTNC hardware and software and is active as long as the control is switched on. The presence of a technical fault or an operation error is made known through a plain-language message.

Moreover, the machine manufacturer can define specific PLC error messages.

PLC error messages

Machine-specific error messages

Are defined by the machine manufacturer (e.g., coolant pump defective, protective door open)

The machine manufacturer defines how the control reacts to a PLC error message (NC Stop, EMERGENCY STOP, etc.)

The machine manufacturer defines whether the control can still be operated or has to be rebooted after a PLC error message.

If you have any questions, please contact your machine manufacturer.

NC error messages

Are part of the HEIDENHAIN NC software.

Can be subdivided into error messages that result from operation, programming and machine applications and those that indicate a technical defect (devices, electronic and mechanical components, etc.)

HEIDENHAIN defines how the control reacts to an NC error message (NC Stop, EMERGENCY STOP, etc.)

HEIDENHAIN defines whether the control can still be operated or has to be rebooted after an NC error message.

If you have any questions, please contact your machine manufacturer and/or HEIDENHAIN.

Is the displayed error message an NC or PLC error message?

Call the ERR window or the log to answer this question:
