4.2 List of faults and alarms
246: Voltage tolerance acceleration (p9589/p9389).
247: SDI tolerance (p9564/p9364).
248: SDI positive upper limit (7FFFFFFF hex).
249: Position actual value (r9713[0/1]) - SDI tolerance (p9564/p9364).
250: Position actual value (r9713[0/1]) + SDI tolerance (p9564/p9364).
251: SDI negative lower limit (80000001 hex).
252: SDI stop response (p9566/p9366).
253: SDI delay time (p9565/p9365).
254: Setting, behavior during pulse suppression (p9509/p9309).
256: Status image of monitoring functions SOS, SLS, SLP, test stop, SBR, SDI (result list 1 ext) (r9710).
258: Fault tolerance, actual value sensing encoderless (p9585/p9385).
1000: Watchdog timer has expired. Too many signal changes have occurred at the F-DI.
1001: Initialization error of watchdog timer.
1005: Pulses already suppressed for test stop selection.
1011: Acceptance test status between the monitoring channels differ.
1020: Cyc. communication failure between the monit. cycles.
1041: Current absolute value too low (encoderless)
1042: Current/voltage plausibility error
1043: Too many acceleration phases
1044: Actual current values plausibility error.
6000 ... 6999:
Error in the PROFIsafe control.
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 safety fault F01611.
Message values that have not been listed are only for internal Siemens troubleshooting.
See also: r9725 (SI Motion diagnostics STOP F)
Remedy: For message value = 0:
- no error was identified in this monitoring channel. Note the error message of the other monitoring channel (for
processor 2: C30711).
For message value = 3:
Commissioning phase:
- check the setting of the gear parameters on both monitoring channels (p9521/p9321, p9522/p9322).
- check the numerator of the gear ratio to ensure that it takes into account the motor pole pair number (p9522/p9322).
In operation:
- increase the ramp-function generator ramp-up/down time (p1120/p1121), reduce the dynamic performance of the
drive.
For message value = 1 ... 999:
- if the message value is listed under cause: Check the crosswise-compared parameters to which the message value
refers.
- copy the safety parameters.
- carry out a POWER ON (switch-off/switch-on).
- upgrade the Control Unit software.
For message value = 1000:
- investigate the signal associated with the F-DI (contact problems).
For message value = 1001:
- carry out a POWER ON (switch-off/switch-on).
- upgrade the Control Unit software.
For message value = 1005:
- check the conditions for pulse enable.
For message value = 1011:
- for diagnostics, refer to parameter (r9571).
For message value = 1020:
- carry out a POWER ON (switch-off/switch-on).
- replace Control Unit.
