Troubleshooting
Troubleshooting
•
Check for proper grounding and loose
connections.
•
Check for proper wire size.
•
Check the motor cables for short circuits or
leakage currents.
WARNING 42, Overload of digital output on X30/6 or
overload of digital output on X30/7
For terminal X30/6, check the load connected to terminal
X30/6 or remove the short circuit connection. Also check
parameter E-56 Term X30/6 Digi Out (OPCGPIO) (General
Purpose I/O OPCGPIO General Purpose I/O).
For terminal X30/7, check the load connected to terminal
X30/7 or remove the short circuit connection. Check
parameter E-57 Term X30/7 Digi Out (OPCGPIO) (General
Purpose I/O OPCGPIO General Purpose I/O).
ALARM 46, Power card supply
The supply on the power card is out of range.
There are 3 supplies generated by the switch mode supply
(SMPS) on the power card:
•
24 V.
•
5 V.
±18 V.
•
When powered with 3-phase mains voltage, all 3 supplies
are monitored.
Troubleshooting
•
Check for a defective power card.
•
Check for a defective control card.
•
Check for a defective option card.
•
If a 24 V DC supply is used, verify proper supply
power.
WARNING 47, 24 V supply low
The supply on the power card is out of range.
There are 3 supplies generated by the switch mode supply
(SMPS) on the power card:
•
24 V.
•
5 V.
±18 V.
•
Troubleshooting
•
Check for a defective power card.
WARNING 48, 1.8 V supply low
The 1.8 V DC supply used on the control card is outside of
the allowable limits. The supply is measured on the control
card.
Troubleshooting
•
Check for a defective control card.
•
If an option card is present, check for
overvoltage.

WARNING 49, Speed limit
The warning is shown when the speed is outside of the
specified range in F-18 and F-17. When the speed is below
the specified limit in parameter H-36 Trip Speed Low [RPM]
(except when starting or stopping), the frequency
converter trips.
ALARM 50, Auto tune calibration failed
Contact the GE supplier or GE service department.
ALARM 51, Auto tune check U
The settings for motor voltage, motor current, and motor
power are wrong.
Troubleshooting
•
ALARM 52, Auto tune low I
The motor current is too low.
Troubleshooting
•
ALARM 53, Auto tune motor too big
The motor is too large for the Auto tune to operate.
ALARM 54, Auto tune motor too small
The motor is too small for the Auto tune to operate.
ALARM 55, Auto tune parameter out of range
Auto tune cannot run because the parameter values of the
motor are outside of the acceptable range.
ALARM 56, Auto tune interrupted by user
The AMA is manually interrupted.
ALARM 57, Auto tune internal fault
Try to restart Auto tune. Repeated restarts can overheat
the motor.
ALARM 58, Internal fault
Contact the GE supplier.
WARNING 59, Current limit
The current is higher than the value in
parameter F-43 Current Limit. Ensure that motor data in
parameters P-02, P-03, P-06, P-07, F-04, and F-05 is set
correctly. Increase the current limit if necessary. Ensure that
the system can operate safely at a higher limit.
WARNING 60, External interlock
A digital input signal indicates a fault condition external to
the frequency converter. An external interlock has
commanded the frequency converter to trip. Clear the
external fault condition. To resume normal operation, apply
24 V DC to the terminal programmed for external interlock,
and reset the frequency converter.
WARNING 62, Output frequency at maximum limit
The output frequency has reached the value set in
parameter F-03 Max Output Frequency 1. Check the
application for possible causes. Possibly increase the
output frequency limit. Be sure that the system can
