Indramat · Indradrive
This fault indicates a problem during the internal diagnostic check of safety-related interrupting circuits, often associated with Safe Torque Off (STO) or Safe Stop functions. The drive detected an inconsistency or malfunction in the circuitry designed to safely cut off power to the motor.
Click steps to track your progress.
Power cycle the IndraDrive.
Verify all external wiring to the safety inputs (e.g., STO, emergency stop) for proper connections, shorts, or open circuits.
Review the safety configuration parameters in the IndraDrive to ensure they match the implemented safety logic.
Check for any external safety devices (e.g., emergency stop buttons, safety gates) that might be stuck or incorrectly wired, affecting the circuit.
If external factors are ruled out, the internal safety monitoring hardware of the IndraDrive or its safety option module may be defective.
