C30770 SI Motion P2: 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: None
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 hexadecimal):
yyyyxxxx hex
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 (p10106, 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 (p9307.0) 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.
If the period of a cyclic switching pulse corresponds to twice the value of p10102, then the following formulas should
be checked:
- p10102 < (tp / 2) - td (discrepancy time must be less than half the period minus the actual discrepancy time)
- p10102 >= p9300 (discrepancy time must be at least p9300)
- p10102 > td (discrepancy time must be greater than the switch discrepancy time that may actually occur)
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 p9300).
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.
- p11002 < p10117 + 1 ms - td
- p10102 > td
- p10102 >= p9300
Example:
For a 12 ms SI monitoring cycle and a switching frequency of 110 ms (p10117 = 0), the maximum discrepancy time
which can be set is as follows:
p10102 <= (110/2 ms) - 12 ms = 43 ms
Rounded-off, p10102 <= 36 ms is obtained (since the discrepancy time can only be accepted as a whole SI
monitoring cycle, the value will need to be rounded up or down to a whole SI monitoring cycle if the result is not an
exact multiple of an SI monitoring cycle).
