Message value: %1 Drive object: A_INF, B_INF, S_INF, SERVO, TM41, TM54F_MA, TM54F_SL, VECTOR Reaction: NONE Acknowledge: IMMEDIATELY Cause: The safety input terminals or outpu t terminals show a different state longer than that parameterized in p10002. Fault value (r0949, interpret hexadecimal): yyyyxxxx hex xxxx: The safety-relevant input terminal s F-DI indicate a discrepancy. Bit 0: Discrepancy for F-DI 0... Bit 9: Discrepancy for F-DI 9 yyyy: The safety-relevant output termi nals F-DO indicate a discrepancy. Bit 0: Discrepancy for F-DO 0... Bit 3: Discrepancy for F-DO 3 Note: If several discrepancy errors occur c onsecutively, then this fault is only signaled for the first error that occurs. The following possibilities exist of diagnosing all of the discrepancy errors: - in the commissioning software, evaluate the input states and output states of the TM54F. All discrepancy errors are displayed here. - compare parameters p10051 and p10052 from the TM54F master and TM54F slave for discrepancy. Remedy: Check the wiring of the F-DI and F-DO (contact problems). Note: A discrepancy of the F-DO also occurs (in this s pecial case, in conjunction with fault F35150 for the TM54F slave), if, after replacing a Motor Modul e, it was forgotten to acknowledge this. When replacing a Motor Module, carry out the following steps: - start the copy function for the node id entifier on the TM54F (p9700 = 1D hex). - acknowledge the hardware CRC on the TM54F (p9701 = EC hex). - save all parameters (p0977 = 1). - carry out a POWER ON (power off/on) for all components. F-DI: Failsafe Digital Input F-DO: Failsafe Digital Output Discrepancy errors of the F-DIs can only be complete ly acknowledged if, after the cause of the error has been resolved, safe acknowledgement was carr ied out (refer to p10006). As long as safety acknowledgement was not carried out, the corresponding F-DI stays in the safe state.
