HEIDENHAIN ITNC 530 - Annex: Monitoring Functions; Introduction; During Start-Up

July 2010 3 – 661
3 Annex: Monitoring Functions
3.1 Introduction
iTNC 530 features comprehensive monitoring functions.
Values are defined for axis positions and dynamic response of the machine. If the specified
values are exceeded, the control displays an error message and stops the machine.
In this chapter you can look up which monitoring functions exist on iTNC 530 and how they are
defined.
3.2 During Start-Up
EMERGENCY STOP
test
In the event of hazardous errors the control switches off the Control-is-ready output.
An EMERGENCY STOP must be generated. --> The EMERGENCY STOP chain must be
interrupted.
Since this is a function important for the safety on the machine, it is checked via the
EMERGENCY STOP test every time the line power is switched on.

DANGER
Active monitoring functions are essential for safe machine operation!
Safe machine operation is not possible if the monitoring functions are switched off.
Uncontrolled axis movements are not detected.
 Deactivated monitoring functions or changed tolerance values may result in damage to
persons or equipment.
 You must not switch off any of the monitoring functions!
Note
For the wiring recommended by HEIDENHAIN, refer to the circuit diagram; --> See “Annex:
Principle of Function of the iTNC 530 Control” on page 2 – 657.
The Control-is-ready signal acknowledgment has to occur within 1 s.
