Offizielle Schritte zur Fehlerbehebung
Message value: %1 Drive object: All objects Reaction: OFF2 Acknowledge: IMMEDIATELY (POWER ON) Cause: The write request for one or several Safety Integrated parameters on the Motor Module (MM) was rejected. Note: This fault does not result in a safety stop response. Fault value (r0949, interpret decimal): 10: An attempt was made to enable the STO function although this cannot be supported. 11: An attempt was made to enable the SBC function although this cannot be supported. 13: An attempt was made to enable the SS1 function although this cannot be supported. 14: An attempt was made to enable the safe motion monitoring function with t he higher-level control, although this cannot be supported. 15: An attempt was made to enable the motion moni toring functions integrated in the drive although these cannot be supported. 16: An attempt was made to enable the PROFIsafe communication - although this cannot be supported or the version of the PROFIsafe driver used on the CU and MM is different. See also: r9771 (SI common functions (Control Un it)), r9871 (SI common functions (Motor Module) Remedy: Re fault value = 10, 11, 13, 14, 15, 16: - check whether there are faults in the safety function alignment between the Control Unit and the Motor Module involved (F01655, F30655) and if requir ed, carry out diagnostics for the faults involved. - use a Motor Module that supports the required f unction ("Safe Torque Off", "Safe Brake Control", "PROFIsafe/PROFIsafe V2", "motion monito ring functions integrated in the drive"). - upgrade the Motor Module software. - upgrade the Control Unit software. Note: CU: Control Unit MM: Motor Module SBC: Safe Brake Control SI: Safety Integrated SS1: Safe Stop 1 (corresponds to Stop Category 1 acc. to EN60204) STO: Safe Torque Off / SH: Safe standstill
