Siemens SINAMICS S210 Operating Instructions Manual page 519

Cause: The drive has identified a difference between the input data or results of the monitoring functions and initiated A30711. Safe
operation is no longer possible.
At least one monitoring function is active, so that after the parameterized timer has expired, message F30701 is output.
The following message values may also occur in the following cases if the cause that is explicitly mentioned does not apply:
- incorrect synchronization.
Message value (r2124, interpret decimal):
0 ... 999:
Number of the cross-compared data that resulted in this message.
The significance of the individual message values is described in message A01711.
1000: Watchdog timer has expired. Too many signal changes have occurred at safety-relevant inputs.
1001: Initialization error of watchdog timer.
1005: STO already active for test stop selection.
1011: Acceptance test status between the monitoring channels differ.
1012: Plausibility violation of the encoder actual value.
1020: Cyc. communication failure between the monit. channels.
1021: Cyclic communication failure between the monitoring channel and encoder evaluation.
1023: Error in the effectiveness test in the DRIVE-CLiQ encoder
1030: Encoder fault detected from another monitoring channel.
1045: CRC of the standstill position incorrect.
5000 ... 5140:
PROFIsafe message values.
For these message values, the failsafe control signals (Failsafe Values) are transferred to the safety functions.
The significance of the individual message values is described in message A01711.
6000 ... 6166:
PROFIsafe message values (PROFIsafe driver for PROFIBUS DP V1/V2 and PROFINET).
For these message values, the failsafe control signals (Failsafe Values) are transferred to the safety functions. If "SS1 after
failure of PROFIsafe communication" is parameterized, then transfer of the Failsafe Values is delayed.
The significance of the individual message values is described in safety fault F01611.
