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
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).
Note:
F-DI: Failsafe Digital Input
F-DO: Failsafe Digital Output
A01772 SI Motion P1 (CU): Test stop failsafe inputs/outputs active
Message value: -
Message class: Safety monitoring channel has identified an error (10)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: The test stop for the fail-safe digital inputs (F-DI) and/or fail-safe digital outputs (F-DO) is presently being performed.
Note:
F-DI: Failsafe Digital Input
F-DO: Failsafe Digital Output
Remedy: The alarm disappears automatically after successfully ending or canceling (when a fault condition occurs) the test
stop.
F01773 SI Motion P1 (CU): Test stop error
Message value: %1
Message class: Safety monitoring channel has identified an error (10)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: A fault has occurred on the CU side during the test stop for the fail-safe outputs.
Fault value (r0949, interpret hexadecimal):
RRRVWXYZ hex:
R: Reserved.
V: Actual state of the DO channel concerned (see X) on the CU (corresponds to the states read back from the
hardware, bit 0 = DO 0, bit 1 = DO 1, etc.).
W: Required state of the DO channel concerned (see X, bit 0 = DO 0, bit 1 = DO 1, etc.).
X: DO channels involved, which indicate an error (bit 0 = DO 0, bit 1 = DO 1, etc.).
Y: Reason for the test stop fault.
Z: State of the test stop in which the fault has occurred.
Y: Reason for the test stop fault
Y = 1: MM side in incorrect test stop state (internal fault).
Y = 2: Expected states of the DOs were not fulfilled (CU305: readback via DI 22 / CU240 readback DI 5).
Y = 3: Incorrect timer state on CU side (internal fault)
Y = 4: Expected states of the diag DOs were not fulfilled (CU305: internal readback on MM channel).
Y = 5: Expected states of the second diag DOs were not fulfilled (CU305: internal readback on CU channel).
X and V indicate the DI or Diag-DO state dependent upon the reason for the fault (2, 4 or 5).
In the event of multiple test stop faults, the first one that occurred is shown.
Z: Test stop state and associated test actions
Z = 0 ... 3: Synchronization phase of test stop between CU and Motor Module no switching operations
Z = 4: DO + OFF and DO - OFF
Z = 5: Check to see if states are as expected
Z = 6: DO + ON and DO - ON
Z = 7: Check to see if states are as expected
