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).
Note:
F-DI: Failsafe Digital Input
C30798 SI Motion P2: Test stop running
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The test stop is active.
Remedy: Not necessary.
The message is withdrawn when the test stop is finished.
C30799 SI Motion P2: Acceptance test mode active
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The acceptance test mode is active.
Remedy: Not necessary.
The message is withdrawn when exiting the acceptance test mode.
N30800 (F) Power unit: Group signal
Reaction: OFF2
Acknowledge: NONE
Cause: The power unit has detected at least one fault.
Remedy: Evaluate the other messages that are presently available.
F30802 Power unit: Time slice overflow
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A time slice overflow has occurred.
Remedy: - carry out a POWER ON (power off/on) for all components.
- upgrade firmware to later version.
- contact the Hotline.
F30804 (N, A) Power unit: CRC
Reaction: OFF2 (OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: A CRC error has occurred for the power unit.
Remedy: - carry out a POWER ON (power off/on) for all components.
- upgrade firmware to later version.
- contact the Hotline.
