公式トラブルシューティング手順
Message value: %1 Drive object: SERVO, VECTOR Reaction: NONE (OFF1, OFF2, OFF3) Acknowledge: IMMEDIATELY (POWER ON) Cause: The drive-based "Safety Integrated" function in the C ontrol Unit (CU) has detected a fault in the data cross-check between the CU and Motor Module (MM) and initiated a STOP F. As a result of this fault, after the parameteriz ed transition has expired (p9658), fault F01600 (SI CU: STOP A initiated) is output. Fault value (r0949, interpret decimal): 0: Stop request from the Motor Module. 1 to 999: Number of the cross-checked data that resulted in this fault. This number is also displayed in r9795. 1: SI monitoring clock cycle (r9780, r9880). 2: SI enable safety functions (p9601, p9801). Cros swise data comparison is only carried out for the supported bits. 3: SI SGE changeover tolerance time (p9650, p9850). 4: SI transition period STOP F to STOP A (p9658, p9858). 5: SI enable Safe Brake Control (p9602, p9802). 6: SI Motion enable, safety-relevant functions (p9501, internal value). 7: SI pulse suppression delay time for Safe Stop 1 (p9652, p9852). 8: SI PROFIsafe address (p9610, p9810). 1000: Watchdog timer has expired. Within a per iod corresponding to approximately 5 * p9650, too many switching operations have occurred at terminal EP of the Motor Module, or STO (including subsequent responses) has been triggered t oo frequently via PROFIsafe/TM54F. 1001, 1002: Initialization erro r, change timer / check timer. 2000: Status of the STO selection on the Control Unit and Motor Module are different. 2001: Feedback signal for safe pulse suppression on the Control Unit and Motor Module are different. 2002: Status of the delay timer SS1 on the Control Unit and Motor Module are different. 2004: Status of the STO selection for modules connected in parallel are different. 2005: Feedback signal of the safe pulse suppre ssion on the Control Unit and Motor Modules connected in parallel are different. Remedy: Re fault value = 1 to 5 and 7 to 999: - check the cross-checked data that resulted in a STOP F. - carry out a POWER ON (power off/on) for all components. - upgrade the Motor Module software. - upgrade the Control Unit software. Re fault value = 6: - carry out a POWER ON (power off/on) for all components. - upgrade the Motor Module software. - upgrade the Control Unit software. Re fault value = 1000: - check the EP terminal at the Motor Module (contact problems). - PROFIsafe: rectify contact problems/faults on the PROFIBUS master/PROFINET controller. - check the wiring of the fail-safe inputs on TM54F (contact problems). Re fault value = 1001, 1002: - carry out a POWER ON (power off/on) for all components. - upgrade the Motor Module software. - upgrade the Control Unit software. Re fault value = 2000, 2001, 2002, 2004, 2005: - check the tolerance time SGE changeover and if required, increase the value (p9650/p9850, p9652/p9852). - check the wiring of the safety-relevant inputs (SGE) (contact problems). - check the causes of STO selection in r9772. Ac tive SMM functions (p9501= 1) can also cause STO to be selected. - replace the Motor Module involved. SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 Note: CU: Control Unit EP: Enable Pulses (pulse enable) MM: Motor Module SGE: Safety-relevant input SI: Safety Integrated SS1: Safe Stop 1 (corresponds to Stop Category 1 acc. to EN60204) STO: Safe Torque Off / SH: Safe standstill SMM: see r9772
