Switching off the motor when SLS is active

Description
If you switch off the motor with the SLS function active using the OFF1 or OFF3 command,
e.g. when reaching limit switches, the following happens:
1. The inverter brakes the motor with the OFF1 or OFF3 ramp-down time.
2. Also while braking, the inverter monitors the motor speed.
3. When reaching the standstill monitoring, the inverter safely switches off the motor torque
4. The motor coasts down to a standstill.
