Message value: %1 Drive object: A_INF, B_INF, S_INF, SERVO, TM41, TM54F_MA, TM54F_SL, VECTOR Reaction: OFF2 Acknowledge: IMMEDIATELY (POWER ON) SINAMICS-Alarms Cause: The write request for one or several Safety Integrated parameters on the Control Unit (CU) was rejected. Note: This fault does not result in a safety stop response. Fault value (r0949, interpret decimal): 1: The Safety Integrated password is not set. 2: A reset of the drive parameters was selected. However, the Safety Integrated parameters cannot be reset, as Safety Integrated is presently enabled. 3: The interconnected STO input is in the simulation mode. 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. 12: An attempt was made to enable the SBC function although this cannot be supported for a parallel circuit configuration. 13: An attempt was made to enable the SS1 function although this cannot be supported. 14: 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. 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 STO function although this cannot be supported when the internal voltage protection (p1231) is enabled. See also: p0970, p3900, r9771, r9871 Remedy: Re fault value = 1: - set the Safety Integrated password (p9761). Re fault value = 2: - inhibit Safety Integrated and again reset the drive parameters. Re fault value = 3: - end the simulation mode for the digital input (p0795). Re fault value = 10, 11, 12, 13, 14, 15: - 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. Re fault value = 16: - inhibit the internal voltage protection (p1231). 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 See also: p9501, p9601, p9620, p9761, p9801
