Switching the motor on after an internal event
Procedure
To switch the motor in the example above on again, proceed as follows:
1. Issue an OFF1 command (ON/OFF1 = 0).
2. Acknowledge the internal event in one of the following ways:
– Fail-safe acknowledgment using PROFIsafe control word 0, bit 7 = 0 → 1 → 0
– Fail-safe acknowledge signal via a fail-safe digital input: F‑DI = 0 → 1 → 0.
– Select the STO function and deselect again (PROFIsafe control word 0, bit 0 or F-DI).
– Select the SS1 function and deselect again (PROFIsafe control word 0, bit 1 or F-DI).
– Switch off the power supply voltage of the inverter and switch on again.
3. Acknowledge the inverter with the "standard" acknowledge signal.
4. Switch on the motor (ON/OFF1 = 1).
You have acknowledged the internal event and switched on the motor again.
