Cause : Safe torque off - comes when Safe torque off function is active, ie safety circuit signal connected to connector STO is lost.
This is a programmable warning: 31.22 STO indication run/stop
- Check safety circuit connections description of parameter 31.22 STO indication run/stop.
- Check wiring for safe torque off.
