Faults and alarms
List of faults and alarms
C01716 SI Motion P1: Tolerance for safe motion direction exceeded
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The tolerance for the "safe motion direction" function was exceeded. The drive is stopped as a result of the config-
ured stop response (p9566).
Message value (r9749, interpret decimal):
0: Tolerance for the "safe motion direction positive" function exceeded.
1: Tolerance for the "safe motion direction negative" function exceeded.
Remedy: - check the traversing/motion program in the control.
- check the tolerance for "SDI" function and if required, adapt (p9564).
This message can be acknowledged as follows:
- Deselect the "SDI" function and select again.
- Perform a safe acknowledgment via F-DI or PROFIsafe.
Note:
SDI: Safe Direction
SI: Safety Integrated

C01770 SI Motion P1: Discrepancy error of the failsafe inputs
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The fail-safe digital inputs (F-DI) show a different state longer than that parameterized in p10002 / p10102.
Fault value (r0949, interpret binary):
Bit 0: Discrepancy error for F-DI 0
Bit 1: Discrepancy error for F-DI 1
...
Note:
If several discrepancy errors occur consecutively, then this fault 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 acknowledge-
ment 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 fre-
quency.
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
Example:
For a 12 ms SI monitoring cycle and a switching frequency of 110 ms (p10017 = 0), the maximum discrepancy time
which can be set is as follows:
p10002 <= (110/2 ms) - 12 ms = 43 ms
Rounded-off, p10002 <= 36 ms is obtained (since the discrepancy time can only be accepted as a whole SI moni-
toring 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).
