•
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 signals:
•
"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 signals:
•
"STO is active" (r9772.0 = 1).
