Behavior in the event of a safe operating stop
Analog to the NC/PLC interface stop signals, the behavior in the event of a stop can also be
adjusted by activating the safe operating stop (SBH):
Stop condition
Safe operating stop in
the event of active tar‐
get velocity limit
In the default setting, Bit 12 is set to "1", i.e. in the event of a stop resulting from activation of
the safe stop, current movements are aborted and new handwheel pulses ignored.
Prerequisite for an interpolatory stop is an active target velocity limit (i.e., MD36933
$MA_SAFE_DES_VELO_LIMIT > 0).
