3-4 Troubleshooting and Error Codes
DSP Reset Fault
22
Power-up has been attempted with
an Open Stop contact or Closed
Start contact.
Check/verify wiring and contact opera-
tion.
DSP Timeout Fault
28
Refer to the “Description” and “Action” statements for C167 Watchdog (F17)
on page 3.3.
EE Init Read
53
1. Gate Drive Bd. replacement (re-
quires re-initialization).
2. Trouble reading EEPROM dur-
ing initialization.
1. Reset to factory defaults & cycle in-
put power.
2. Check all connections to Power/
Driver Board. Replace board or com-
plete drive as needed.
EE Init Value
54
Stored parameter value out of
range on initialization.
1. Reset to factory defaults & cycle in-
put power.
2. Check all connections to the Power/
Driver Bd. Replace the board or
complete drive as needed.
EEprom Checksum
66
The checksum read from the
EEPROM does not match the
checksum calculated from the
EEPROM data.
1. Reset to factory defaults & cycle in-
put power.
2. Check all wire and cable connec-
tions to the Power Driver Board.
Replace Power Driver Board or com-
plete drive as required.
EEprom Fault
32
EEPROM is being programmed
and will not write a new value.
Check all wire and cable connections
to the Main Control Board. Replace
Main Control Board or complete drive
as required.
Encoder Loss
60
The drive has detected an error in
the encoder signals at TB3, termi-
nals 31-36. The error could be due
to a:
1. Loss of 1 or more channels.
2. Loss of quadrature.
3. Loss of differential signal (A & A
NOT or B & B NOT were high at
the same time).
Check encoder and wiring.
Fgnd 10ms Over
52
Microprocessor loop fault. Occurs if
a 10ms interrupt is pending before
the current interrupt is complete.
Replace Main Control Board or com-
plete drive as required.
Ground Fault
13
A current path to earth ground in
excess of 100A has been detected
at one or more of the drive output
terminals. NOTE: If ground current
exceeds 220% of drive rated cur-
rent, “Overcurrent Flt” may occur
instead of Ground Fault.
Check the motor and external wiring to
the drive output terminals for a
grounded condition.
Ground Warning
57
A current path to earth ground in
excess of 2A has been detected at
one or more of the drive output ter-
minals. See [Ground Warning].
Check the motor and external wiring to
the drive output terminals for a
grounded condition.
Hardware Trap
18
Refer to the “Description” and “Action” statements for C167 Watchdog (F17)
on page 3.3.
