Code 230711: <location>SI MM MM: Defect in a monitoring channel

Message value: %1 Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: IMMEDIATELY (POWER ON) Cause: When cross-checking and comparing the two monito ring channels, the drive detected a difference between the input data or results of the monitoring functions and initiated a STOP F. One of the monitoring functions no longer reli ably functions - i.e. safe oper ation is no longer possible. If at least one monitoring function is active, then after the parameterized timer has expired, the message C30701 "SI Motion: STOP B initiated" is out put. The message is output with message value 1031 when the Sensor Module hardware is replaced. Message value (r9749, interpret decimal): 0... 999: Number of the cross-checked data that resulted in this message. Refer to safety message C01711for a description of the individual data. The significance of the individual message values is described in safety message C01711 of the Control Unit. 1000: Watchdog timer has expired. Too many signal changes have occurred at safety-relevant inputs. 1001: Initialization error of watchdog timer. 1005: Pulses already suppressed for test stop selection. 1011: Acceptance test status between the monitoring channels differ. 1012: Plausibility violation of the actual value from the encoder. 1020: Cyc. communication failure between the monit. cycles. 1021: Cyc. communication failure betw een the monit. channel and Sensor Module. 1023: Error during the effectivity test in the Sensor Module. 1030: Encoder fault detected from another monitoring channel. 1031: Data transfer error between the monitoring channel and the Sensor Module. 5000... 5140: PROFIsafe message values. The significance of the individual message values is described in safety message C01711 of the Control Unit. 6000... 6166: PROFIsafe message values (PROFIsafe driver for PROFIBUS DP V1/V2 and PROFINET). The significance of the individual message values is described in safety message C01711 of the Control Unit. See also: p9555 (SI Motion transition time STOP F to STOP B (Control Unit)), r9725 (SI Motion, diagnostics STOP F) Remedy: Re message value = 1030: - check the encoder connection. - if required, replace the encoder. Re message value = 1031: When replacing a Sensor Module, carry out the following steps: - start the copy function for the node id entifier on the drive (p9700 = 1D hex). - acknowledge the hardware CRC on the drive (p9701 = EC hex). - save all parameters (p0977 = 1). - carry out a POWER ON (power off/on) for all components. The following always applies: - check the encoder connection. - if required, replace the encoder. Re other message values: - The significance of the individual message val ues is described in safety message C01711 of the Control Unit. Note: This message can only be acknowledged via the Terminal Module 54F (TM54F) or PROFIsafe.
