Table 9-1 Fault Descriptions and Corrective Actions
Fault Code
Description
Corrective Action
Factory Default
parameters have been
loaded
Press STOP key, drive is ready to configure for particular
application.
Instantaneous over
current on drive
output.
Excess load on the
motor.
Over temperature on
the drive heatsink
If the fault occurs immediately when enabling the drive,
disconnect the motor cable from the output terminals of the
drive and restart the drive. If the fault re-occurs with no motor
connected, contact your Baldor District Office. If the drive
runs correctly without motor connected, check the motor,
motor cable and any connections or junction boxes for phase
– phase and phase – earth short circuits. Wherever possible,
motors and connection cables should be checked with a high
voltage insulation tester prior to connection to the drive.
Ensure that no switching devices, such as contactors or local
isolators are switching during operation of the drive.
Check the motor cable length does not exceed the specified
maximum.
Ensure the motor nameplate parameters are correctly entered,
P1-01, P1-02, P1-03. If operating in Vector mode (P4-01 – 0
or 1), also check the motor power factor in P4-05.
Ensure an autotune has been successfully completed for the
connected motor.
Check the load mechanically for a jam or stalled condition, or
shock loads.
Increase the ramp up time in P1-10.
If operating in Vector mode (P4-01 – 0 or 1), reduce the speed
loop gain in P4-03.
.
Drive has tripped
on overload after
delivering >100% of
value in P1-02 for a
period of time.
Check to see when the decimal points are flashing (drive in
overload) and either increase acceleration rate or reduce the
load. Check motor cable length is within spec. Ensure the
motor nameplate parameters are correctly entered, P1-01,
P1-02, and P1-03. If operating in Vector mode (P4-01 – 0 or
1), also check the motor power factor in P4-05. Ensure an
autotune has been successfully completed for the connected
motor. Check the load mechanically to ensure it is free, and no
jams, blockages or other mechanical faults exist.
Brake circuit over
current
Check the cabling to the brake resistor. Check the brake
resistor value. Ensure minimum resistance values from the
rating tables are observed.
Brake resistor
overload
Increase deceleration time, reduce load inertia or add further
brake resistors in parallel, observing the minimum resistance
value for the drive in use.
Fast over current trip
Check wiring to motor, look for Phase to Phase or Phase to
Earth short circuit. Check drive temperature, additional space
or cooling needed?
Check drive is not forced into overload.
.
Over voltage on DC
bus
Supply problem, or increase decel ramp time P1-11.
