Code 201751: <location>SI Motion CU: eff.test error safe encoder

Message value: %1 Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: IMMEDIATELY (POWER ON) Cause: The DQ encoder used for the safety-relevant motion monitoring functions signal s an effectiveness test error. Message value (r9749, interpret decimal): 1 - TFD bit in EncoderStatusWord2 set in last effectiveness test set 2 - Actual effectiveness test no. in last ef fectiveness test set smaller/greater than expected 3 - IG1/IG2 bits in EncoderStatusWord2 in la st effectiveness test set longer than expected 4 - F1/F2 bits in EncoderStatusWord2 in last effectiveness test set not dynamized 5 - Effectiveness tests performed too frequently 6 - LS1/LS2 were not frozen during effectiveness test 7 - Effectiveness tests performed too rarely or not at all Remedy: - check the encoder connection. - replace the encoder. This message can be acknowledged as follows: - motion monitoring functions integrated in the driv e: Via Terminal Module 54F (TM54F) or PROFIsafe - motion monitoring functions with SINU MERIK: Via the machine control panel.
