Safely Limited Speed, Sls - Siemens SINAMICS G120 Function Manual

No.
SS1 is not active.

2. Switch on the motor (ON command).
3. Ensure that the correct motor is running.
4. Select SS1 while the motor is running.
Note: Test each configured activation, e.g. via digital inputs and PROFIsafe.
5. Check the following:
The motor speed decreases in line with the selected ramp time (if necessary, use a stopwatch).

The inverter indicates:

"SS1 is selected" (r9720.1 = 0).
"SS1 is active" (r9722.1 = 1).
The motor coasts to a standstill after the standstill detection threshold has been reached.

The inverter indicates:

"STO is active" (r9772.0 = 1).
A mechanical brake brakes the motor and holds it to ensure that it remains at a standstill.

The inverter indicates neither faults nor alarms for safety functions.

6. Deselect SS1.
7. Check the following:
The inverter indicates neither faults nor alarms for safety functions.

The inverter indicates:

"STO is not active" (r9722.0 = 0).
"SS1 is deselected" (r9720.1 = 1).
8. Switch the motor off (OFF1 command) and then on again (ON command).
9. Ensure that the correct motor is running.
