Safety Integrated Extended Functions
6.5 Safe Stop 2 (SS2)
Safety Integrated
88 Function Manual, 05/2010, A5E03264275A
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.
