6.11 Monitoring functions
The NC monitors the axis positions and the dynamic response of the machine.
If the fixed values are exceeded, it displays an error message and stops the
machine.
With W1042/W1136 you can switch off the following types of monitoring for
individual axes:
Position monitoring
Standstill monitoring
Movement monitoring
Nominal speed value monitoring
In the PLC program, PLC inputs specified in MP4132.x can be used axis-
specifically to switch off the monitoring functions. With W524 bits 0 to 7 you
can deactivate the monitoring functions for the axis group, or with W1042/
W1136 for the individual axes. With W524 the position control loop is also
opened.
