Carry out a forced checking procedure of the basic functions
Preconditions
● STO is not active.
● The motor is switched on (ON/OFF1 = 1), and is at a standstill (speed setpoint = 0).
Procedure
To start the forced checking procedure, proceed as follows:
1. Select the STO function.
2. The inverter checks its safety-related circuits. This check takes several milliseconds.
3. Deselect the STO function.
4. Check that alarm A01699 is no longer present.
You have performed the forced checking procedure.
