Cause : STO (Safe torque off) requested and it functions correctly.
Parameter 3025 STO OPERATION is set to react with alarm.
If this was not expected reaction to safety circuit interruption, check cabling of safety circuit connected to STO terminals X1C. If different reaction is required, change value of
parameter 3025 STO OPERATION.
Note: Start signal must be reset (toggled to 0) if STO has been used while drive has been running.
