Troubleshooting the Drive Using Error Codes

5.2

Identifying Fault Codes and Recovering

GV3000/SE drive fault codes are shown in table 5.2. To clear a single fault that has
occurred so that the drive can be started again, correct any problems indicated by
the fault code and press the STOP/RESET key on the keypad, or assert the fault
reset from the selected control source (P.000). Because multiple faults can occur
and only the first will be displayed, you must access the error log in order to view all
of the faults that have occurred. See section 5.3 for instructions on how to view the
error log.

Fault Cause

P.011 = 4 or 5 and 4 to 20 mA analog
input is below 2 mA.

Charging bypass contactor did not
close or contact closure was not
sensed by the system.

During drive operation:
Regulator board failure.

After Regulator board replacement:

Unintentional grounding.

Failure on write to non-volatile
memory.

Drive is not detecting feedback from
the encoder.

Function loss input on control terminal
is opened.

Identification process for V/Hz has
been aborted.

Input voltage more than 15% above
nominal. (Note that this is not tested
for in 1-20 HP Power Modules
configured for vector control.)

DC bus voltage too high (capacitor
protection).

Deceleration time too short.

Voltage ripple on DC bus due to
missing input phase or an imbalance
between phases.

Corrective Action

Verify that P.011 is set correctly.

Check that analog input source supply

4 mA.

Check operation of the bypass contactor.
Verify the contactor is closing when the
proper bus voltage is applied.

Replace contactor.

Contact Reliance or replace Regulator
board.

Contact Reliance.

Check isolation between ground and
output terminals. Possible leakage,
current sensor defects; replace sensor.

Connect CS3000 software to upload
parameters or record by hand. Then
replace Regulator board. Parameter
values will be lost when power is cycled.

Check the connection between the
encoder and the drive. Check the
encoder/motor coupling.

Check external interlocks at terminals
16, 20.

See H.019 for identification result.

Check actual line voltage against U.018
or H.021.

Check input line voltage; if necessary,
add transformer.

Increase deceleration time
P.002/P.018/P.023 versus Maximum
Speed/Hz (P.004). Install DB option with
resistors.

Verify that proper voltage is being
applied to the drive. Check all phases.
