GE Industrial Solutions AF-600 FP Fan & Pump Drive (230V to 60HP, 460_575V to 125HP) - Manual (Page 58)

WARNING 40, Overload of digital output terminal 27
Check the load connected to terminal 27 or remove short-
circuit connection. Check E-00 Digital I/O Mode and
E-51 Terminal 27 Mode.
WARNING 41, Overload of digital output terminal 29
Check the load connected to terminal 29 or remove short-
circuit connection. Check E-00 Digital I/O Mode and
E-52 Terminal 29 Mode.
WARNING 42, Overload of digital output on X30/6 or
overload of digital output on X30/7
For X30/6, check the load connected to X30/6 or remove
short-circuit connection. Check E-56 Term X30/6 Digi Out
(OPCGPIO).
For X30/7, check the load connected to X30/7 or remove
short-circuit connection. Check E-57 Term X30/7 Digi Out
(OPCGPIO).
ALARM 45, Earth fault 2
Earth (ground) fault on start up.
Troubleshooting
Check for proper earthing (grounding) and loose
connections.
Check for proper wire size.
Check motor cables for short-circuits or leakage
currents.
ALARM 46, Power card supply
The supply on the power card is out of range.
There are three power supplies generated by the switch
mode power supply (SMPS) on the power card: 24V, 5V,
+/- 18V. When powered with three phase mains voltage,
all three supplied are monitored.
Troubleshooting
Check for a defective power card.
Check for a defective control card.
Check for a defective option card.
If a 24V DC power supply is used, verify proper
supply power.
WARNING 47, 24V supply low
The 24 V DC is measured on the control card. The external
24V DC backup power supply may be overloaded,
otherwise contact your GE supplier.
WARNING 48, 1.8V supply low
The 1.8V DC supply used on the control card is outside of
allowable limits. The power supply is measured on the
control card. Check for a defective control card. If an
option card is present, check for an overvoltage condition.
WARNING 49, Speed limit
When the speed is not within the specified range in F-18
and F-17, the drive will show a warning. When the speed is
below the specified limit in H-36 Trip Speed Low [RPM]
(except when starting or stopping) the drive will trip.
ALARM 50, Auto tune calibration failed
Contact your GE supplier or GE Service Department.
ALARM 51, Auto tune check U
nom
and I
nom
The settings for motor voltage, motor current, and motor
power are wrong. Check the settings in parameters P-02,
P-03, P-06, P-07, F-04 and F-05.
ALARM 52, Auto tune low I
nom
The motor current is too low. Check the setting in
F-43 Current Limit.
ALARM 53, Auto tune motor too big
The motor is too big 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
The parameter values of the motor are outside of the
acceptable range. Auto tune will not run.
ALARM 56, Auto tune interrupted by user
The Auto tune has been interrupted by the user.
ALARM 57, Auto tune timeout
Try to restart Auto tune again. Repeated restarts may over
heat the motor.
ALARM 58, Auto tune internal fault
Contact your GE supplier.
WARNING 59, Current limit
The current is higher than the value in F-43 Current Limit.
Ensure that Motor data in parameters P-02, P-03, P-06,
P-07, F-04 and F-05 are set correctly. Possibly increase the
current limit. Be sure the system can operate safely at a
higher limit.
WARNING 60, External interlock
A digital input signal is indicating a fault condition external
to the drive. An external interlock has commanded the
drive to trip. Clear the external fault condition. To resume
normal operation, apply 24V DC to the terminal
programmed for external interlock. Reset the drive.
WARNING 62, Output frequency at maximum limit
The output frequency has reached the value set in
F-03 Max Output Frequency 1. Check the application to
determine the cause. Possibly increase the output
frequency limit. Be sure the system can operate safely at a
higher output frequency. The warning will clear when the
output drops below the maximum limit.
WARNING/ALARM 65, Control card over temperature
The cutout temperature of the control card is 80
° C.
Troubleshooting
• Check that the ambient operating temperature is
within limits.
• Check for clogged filters.
• Check fan operation.
• Check the control card.
