Delays and safe torque switch off (SS1, “Safe Stop 1”)
The safety function “Safe Stop 1” (SS1, type C) can be requested via various devices
è
Fig. 3.2. The
tain. The safety request is made in 2-channels via switch S1 and to the safety switch device. The safety
switch device switches off the controller enable. If the controller enable of the motor controller is
switched off, the movement is automatically delayed and, if the brake is configured, brake activation is
expected before the control circuit is switched off. After a time set in the safety switch device, the
2-channel output stage is switched off via STO-A/B. Once the output stage has been switched off, it is
output by the floating contact C1-C2.
