Safety Integrated Extended Functions
6.5 Safe Stop 2 (SS2)
Note
Activating SS2 may cause the device (PLC, motion controller) that governs the speed
setpoint to interrupt the ramp function (by triggering OFF2).
The device behaves in this way as a result of a fault reaction triggered by OFF3 activation.
This fault reaction can be avoided by assigning appropriate parameters or appropriate
wiring.
