Figure 6-46 Switching the motor off and on when SDI is active
Procedure
To switch the motor on, proceed as follows:
1. Select STO (or SS1).
2. Deselect STO (or SS1) again.
3. After deselecting STO, wait until the inverter is "ready to switch on".
Alternatively: After deselecting STO, wait a certain time before switching on. We
recommend a wait time of 200 ms.
4. Switch on motor within 5 s after deselecting STO (ON command).
You have switched on the motor again.
