DESCRIPTION
A phase-to-ground fault has been detected
between the drive and motor in this phase.
Excessive current has been detected
between these two output terminals.
The drive was commanded to write default
values to EPROM.
Programmed Current Lmt Val (148) has
been exceeded.
Enabled/disable with Fault Config 1 (238).
Drive rating of 110% for 1 minute or 150%
for 3 seconds has been exceeded.
Inverter section of power structure
hardware detected an unexpected fault
during power stage diagnostics.
The network card connected to DPI port
stopped communicating.
The fault code indicates the offending port
number (71 = port 1, 72 = port 2, etc.).
The drive autotuning default is Calculate,
and the value calculated for IR Drop Volts
is not in the range of acceptable values.
The value for flux amps determined by the
autotune procedure exceeds the pro-
grammed Motor NP FLA (42).
Motor did not come up to speed in the allot-
ted time.
The autotune procedure was canceled by
the user.
DPI port stopped communicating.
An attached peripheral with control capa-
bilities via Logic Source Sel (89) (or OIM
control) was removed.
The fault code indicates the offending port
number (81 = port 1, etc.).
Ixo voltage calculated from motor name-
plate data is too high.
not match the checksum calculated.
The checksum read from the user set does
not match the checksum calculated.
The checksum read from the EPROM does
not match the checksum calculated from
the EPROM data.
The checksum read from the board does
not match the checksum calculated.
ACTION
a. Check the wiring between the drive and
motor.
b. Check motor for grounded phase.
c. Replace drive.
a. Check the motor and drive output terminal
wiring for a shorted condition.
b. Replace drive.
a. Clear the fault or cycle power to the drive.
b. Program the drive parameters as needed.
Check load requirements and Current Lmt Val
(148) setting.
Reduce load or extend Accel Time (140).
a. Cycle power.
b. Call Carrier service.
a. Check communication board for proper
connection to external network.
b. Check external wiring to module on port.
Re-enter motor nameplate data.
a. Reprogram Motor NP FLA (42) with the cor-
rect motor nameplate value.
b. Repeat Autotune (61).
a. Uncouple load from motor.
b. Repeat Autotune (61).
Restart procedure.
a. If module was not intentionally discon-
nected, check wiring to the port. Replace
wiring, port expander, modules, Main Con-
trol board or complete drive as required.
b. Check OIM connection.
Re-enter motor nameplate data.
a. Press reset.
b. Reload user set if used.
Press reset.
Clear the fault or cycle power to the drive.
a. Cycle power to the drive.
b. If problem persists, replace drive.
