"If the machine permits a narrower limitation, these values should be programmed.
With parameter 56 - position supervision (erasable) - and 57 - position supervision (emergency stop), ranges
are set for permanent position supervision of the machine. Supervision is operative as soon as the machine axes
are held in closed loops by the control (after traversing over the reference marks).
Overstepping the tolerances in parameter 56 leads to a control stop (error display "positioning error"), whilst
overstepping the tolerances of parameter 57 makes the contl.ol react with "emergency stop". The error display
"position error" can be cancelled with the
0
CE
-key whereas the "emergency stop" must be cancelled by
switching off the maincs power and - after switching on ag;lin and pressing CE to clear display - the reference
marks must be crossed again.
