Further information
•
When the control is switched on, axes can be traversed to the
limits of the machine because they have not yet been
referenced. Emergency limit switches might be triggered as a
result.
•
The software limit switches and the working area limitation are
not yet operative!
•
The feedrate enable must be set (FST display must not light up
in the program control display).
If no advantage is to be gained from moving several axes
simultaneously, the machine manufacturer must implement the
appropriate interlock in the PLC program.
