Table 7.1 - List of Alarm Codes (continued)
Code Alarm Description Alarm Cause Corrective Action
LIL Low AC input Line AC input line is low.
For SVC, indicates DC bus
is being regulated. No
corrective action is required.
1. Adjust line voltage parameter (H.021 or U.018)
to match actual AC line voltage.
S_Ac Vector Self-Tuning active
Vector Self-Tuning is enabled
and in progress.
1. Allow Vector Self-Tuning procedure to finish.
2. Press keypad STOP/RESET to cancel Self-Tuning
procedure if desired.
S_En Vector Self-Tuning enable
U.008 = ON; Vector Self-
Tuning has been enabled but
not started. 1. Proceed with Vector Self-Tuning procedure, start
drive and allow procedure to begin. Display will
change to S_Ac when drive is started.
2. Change U.008 to OFF to cancel Self-Tuning
procedure and clear S_En if desired.
Identifying Fault Codes and Recovering
ATTENTION: DC bus capacitors retain hazardous voltages after input power has been
disconnected. After disconnecting input power, wait five (5) minutes for the DC bus
capacitors to discharge and then check the voltage with a voltmeter to ensure the DC
bus capacitors are discharged before touching any internal components. Failure to
observe this precaution could result in severe bodily injury or loss of life.
GV3000/SE drive fault codes are shown in Table 7.2. 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.
Table 7.2 – List of Fault Codes
Code Type of Fault Possible Cause Action
Ain Analog input signal loss P.011=4 or 5 and 4 to 20mA
analog input is below 2 mA. Verify that P.011 is set correctly.
Check that analog input source supply
≥
4 mA.
bYC Incorrect precharge status. Precharge initiated and
incorrect status returned Check operation of precharge.
CHS Default parameter restore
(checksum error) Regulator board failure Replace regulator (indicate error message at report)
EC Ground Current Trip Unintentional grounding of the
output. Check isolation between ground and output terminals.
Possible leakage, current sensor defects; replace
sensor.
EEr NVRAM write failure Failure on write to non-volatile
memory, bad NVRAM. Connect CS3000 software to upload parameters.
Then replace Regulator board.
Parameter values will be lost when power is cycled.
Drive is not detecting feedback
from the encoder. Check the connection between the encoder and the
drive. Check the encoder/motor coupling. EL Encoder loss
For SVC operation, conditions
exist for more than 5 seconds
that may result in an inability to
complete a ramp-to-rest stop. For SVC operation, check motor data parameters.
Check U.006. Incorrect magnetizing current may be
generated by performing self-tuning with a load
connected to the motor.
FL Function Loss Function Loss input on control
terminal is opened Check external interlocks at terminals 16-20.
