官方故障排除步驟
Message value: %1 Drive object: A_INF, B_INF, CU_LINK, S_INF, SERVO, TM41, TM54F_MA, TM54F_SL, VECTOR Reaction: OFF2 Acknowledge: IMMEDIATELY (POWER ON) SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 Cause: The "Safety Integrated" function requires a synchroni zation of the safety time slices between the Control Unit (CU) and Motor Module (MM) and between the Control Unit and the higher-level control. This synchronization routine was unsuccessful. Note: This fault results in a STOP A that cannot be acknowledged. Fault value (r0949, interpret decimal): 150: Fault in the synchronization to the PROFIBUS master. All other values: Only for in ternal Siemens troubleshooting. See also: p9510 (SI Motion clock-cycle synchronous PROFIBUS master) Remedy: Re fault value = 150: - check the setting of p9510 (SI Motion clock-cycle synchronous PROFIBUS master) and if required, correct. General: - carry out a POWER ON (power off/on) for all components. - upgrade the Motor Module software. - upgrade the Control Unit software. - upgrade the software of the higher-level control. Note: CU: Control Unit MM: Motor Module SI: Safety Integrated
