官方故障排除步骤
Message value: %1 Drive object: SERVO, VECTOR Reaction: OFF2 Acknowledge: IMMEDIATELY (POWER ON) Cause: The drive-based "Safety Integrated" function in the Control Unit (CU) has detected a fault and initiated a STOP A (pulse suppression via the safety shutdown path of the Control Unit). - forced checking procedure of the safety s hutdown path of the Control Unit unsuccessful. - subsequent response to fault F01611 (defect in a monitoring channel). Fault value (r0949, interpret decimal): 0: Stop request from the Motor Module. 1005: Pulses suppressed although STO not sele cted and there is no internal STOP A present. 1010: Pulses enabled although STO is selected or an internal STOP A is present. 1015: Feedback of the safe pulse suppression for Motor Modules connected in parallel are different. 9999: Subsequent response to fault F01611. Remedy: - select Safe Torque Off and de-select again. - replace the Motor Module involved. Re fault value = 9999: - carry out diagnostics for fault F01611. Note: CU: Control Unit MM: Motor Module SI: Safety Integrated STO: Safe Torque Off / SH: Safe standstill SINAMICS-Alarms
