2-28
Malfunctions with Indications
CP-41
CAM Full (Soft) Internal processor error detected. A coast stop will
be initiated.
1. A loss of one of the 3 phase lines has occurred.
This may not be detected as a phase loss due to
other machines or equipment operating on the
same lines, but will be detected as an imbalance.
Verify that all incoming lines are present and at
the proper level. Execute a Clear Fault to resume
operation.
Execute a CLEAR FAULT and attempt normal operation. If
the fault reoccurs, replace Main Control Board.
CP-42
FIFO Overflow
(Soft)
Internal processor error detected. A coast stop will
be initiated.
Execute a CLEAR FAULT and attempt normal operation. If
the fault reoccurs, replace Main Control Board.
CP-43
FIFO Empty
(Soft)
Internal processor error detected. A coast stop will
be initiated.
Execute a CLEAR FAULT and attempt normal operation. If
the fault reoccurs, replace Main Control Board.
CP-46
Too Many Pos
Xing (Soft)
This fault indicates that too many positive AC line
zero crossings have been detected. This is usually
a result of noisy AC lines. A coast stop will be
initiated.
Monitor the incoming AC lines for excessive noise and
transients. If the lines are stable and free from noise,
execute a CLEAR FAULT and continue operation. If the fault
reoccurs replace the Main Control Board.
CP-47
Positive Xing
(Soft)
This fault indicates that an incorrect positive AC line
crossing has been detected. This is usually a result
of noisy AC lines. A coast stop will be initiated.
Monitor the incoming AC lines for excessive noise and
transients. If the lines are stable and free from noise,
execute a CLEAR FAULT and continue operation. If the fault
reoccurs replace the Main Control Board.
CP-48
Too Many Neg
Xing (Soft)
This fault indicates that too many negative AC line
zero crossings have been detected. This is usually
a result of noisy AC lines. A coast stop will be
initiated.
Monitor the incoming AC lines for excessive noise and
transients. If the lines are stable and free from noise,
execute a CLEAR FAULT and continue operation. If the fault
reoccurs replace the Main Control Board.
CP-49
Negative Xing
(Soft)
This fault indicates that an incorrect negative AC
line crossing has been detected. This is usually a
result of noisy AC lines. A coast stop will be
initiated.
Monitor the incoming AC lines for excessive noise and
transients. If the lines are stable and free from noise,
execute a CLEAR FAULT and continue operation. If the fault
reoccurs replace the Main Control Board.
CP-50
RX Msg Index
(Warning)
Internal processor error was detected and
corrected. Operation is unaffected.
No action is required.
CP-52
No Msg Ready
(Warning)
Internal processor error was detected and
corrected. Operation is unaffected.
No action is required.
CP-58
Illegal Mode Seq
(Soft)
Internal processor error detected. A coast stop will
be initiated.
Execute a CLEAR FAULT and attempt normal operation. If
the fault reoccurs, replace Main Control Board.
CP-60
Phase Missed
(Soft)
Detection of the AC line zero crossing was missed.
This is usually a result of noisy AC lines. A coast
stop will be initiated.
Verify connections in the power structure. Monitor the
incoming AC lines for excessive noise and transients. If the
lines are stable and relatively free from noise, execute a
CLEAR FAULT and continue operation. Check system
grounding. If the fault reoccurs replace the PSI Board first,
then the Main Control Board.
CP-61
Period Variation
(Soft)
The period of the incoming AC lines varied by more
than 0.40ms during power-up synchronization. This
indicates that the AC line frequency is varying by
more than 2Hz. A coast stop will be initiated.
Check the AC lines for frequency variations and correct the
cause. If the line frequency is stable and free from noise,
execute a CLEAR FAULT and continue operation. If the fault
reoccurs, replace the Main Control Board.
CP-62
Period Limit
(Soft)
The period of the incoming AC lines is out of
tolerance during power-up synchronization. This
indicates that the AC line frequency is outside the
45-65Hz operating range. A coast stop will be
initiated.
Measure the AC line frequency and correct the cause if out
of tolerance. If the line frequency is within the operating
range and is free from noise, execute a CLEAR FAULT and
continue operation. If the fault reoccurs replace the Main
Control Board.
CP-63
Fire Delay (Soft) Internal hardware error detected. A coast stop will
be initiated.
Execute a CLEAR FAULT and attempt normal operation. If
the fault reoccurs, replace Main Control Board.
Current Processor Faults
