This message can be acknowledged without a POWER ON as follows (safe acknowledgment):
- Terminal Module 54F (TM54F).
- onboard F-DI (only CU310-2).
- PROFIsafe.
- machine control panel.
C01752 SI Motion P1 (CU): reference position invalid
Message value: %1
Message class: Safety monitoring channel has identified an error (10)
Drive object: VECTOR_G
Component: None
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The transferred reference position is invalid.
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 position into the motion.
Remedy: - unpark axis/encoder.
- acknowledge encoder fault
- deactivate 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
Component: Control Unit (CU)
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 (safe acknowledgment).
Discrepancy errors of an F-DI can only be acknowledged if safe acknowledgment was carried out once after the
cause of the error was resolved (p10006, acknowledgment via PROFIsafe, extended message acknowledgment). As
long as safety acknowledgment was not carried out, the corresponding F-DI stays in the safe state internally.
When the "Extended message acknowledgment" function (p9507.0) is active, the following applies:
If the F-DI assigned for STO or SS1 is in a fail-safe state due to a discrepancy error, then when deselecting via this F-
DI, safe acknowledgment can no longer be executed.
For cyclic switching operations at the F-DI, it may be necessary to adapt the discrepancy time to the switching
frequency.
