Cause : Safe torque off function is active, i.e. safety circuit signal(s) connected to connector XSTO is lost.

1. Programmable warning:

31.22 - STO diagnostics.

2. Check safety circuit connections.

For more information, see drive hardware manual and description of parameter 31.22 - STO diagnostics
