4 Faults and alarms
4.2 List of faults and alarms
Message value (r9749, interpret decimal):
1: It is not possible to directly transfer the reference position (p9573=89).
2: It is not possible to transfer the reference into the motion.
Remedy: - unpark axis/encoder.
- acknowledge encoder fault
- de-activate gearbox stage switchover.
- when referencing via the Safety Control Channel (SCC), enable the function "Referencing via SCC"
(p9501.27/9301.27).
This message can be acknowledged as follows:
- motion monitoring functions integrated in the drive: Via Terminal Module 54F (TM54F) or PROFIsafe
C01770 SI Motion P1 (CU): Discrepancy error of the fail-safe inputs/outputs
Message value: %1
Message class: Safety monitoring channel has identified an error (10)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The fail-safe digital inputs/digital outputs (F-DI/F-DO) show a different state longer than that parameterized in p10002
/ p10102.
Fault value (r0949, interpret bitwise binary):
yyyyxxxx bin
xxxx: Discrepancy error for fail-safe digital inputs (F-DI).
Bit 0: Discrepancy error for F-DI 0
Bit 1: Discrepancy error for F-DI 1
...
yyyy: Discrepancy error for fail-safe digital outputs (F-DO).
Bit 0: Discrepancy error for F-DO 0
...
Note:
If several discrepancy errors occur consecutively, then this message is only signaled for the first error that occurs.
Remedy: - check the wiring of the F-DI (contact problems).
Note:
This message can be acknowledged via F-DI or PROFIsafe.
Discrepancy errors of an F-DI can only be completely acknowledged if safe acknowledgement was carried out once
the cause of the error was resolved (p10006 or acknowledgment via PROFIsafe). As long as safety
acknowledgement was not carried out, the corresponding F-DI stays in the safe state internally.
For cyclic switching operations at the F-DI, it may be necessary to adapt the discrepancy time to the switching
frequency.
If the period of a cyclic switching pulse corresponds to twice the value of p10002, then the following formulas should
be checked:
- p10002 < (tp / 2) - td (discrepancy time must be less than half the period minus the actual discrepancy time)
- p10002 >= p9500 (discrepancy time must be no less than p9500)
- p10002 > td (discrepancy time must be greater than the switch discrepancy time which may actually apply)
td = possible actual discrepancy time (in ms) that can occur with a switching operation. This must correspond to at
least 1 SI monitoring cycle (see p9500).
tp = period for a switching operation in ms.
When debounce p10017 is active, the discrepancy time is directly specified by the debounce time.
If the period of a cyclic switching pulse corresponds to twice the debounce time, then the following formulas should
be checked.
- p10002 < p10017 + 1 ms - td
- p10002 > td
- p10002 >= p9500
