Figure 6-30 OFF1 command when the SLS safety function is active
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
with the STO safety function.
4. The motor coasts down to a standstill.
