ALARM 58, AMA Internal fault
Contact the Honeywell supplier.
WARNING 59, Current limit
The current is higher than the value in 4-18 Current Limit. Ensure that motor data
in parameters 1–20 to 1–25 are set correctly. Possibly increase the current limit. Be
sure that 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 adjustable fre-
quency drive. An external interlock has commanded the adjustable frequency drive
to trip. Clear the external fault condition. To resume normal operation, apply 24 V
DC to the terminal programmed for external interlock. Reset the adjustable fre-
quency drive.
WARNING 62, Output frequency at maximum limit
The output frequency has reached the value set in 4-19 Max Output Frequency.
Check the application to determine the cause. Possibly increase the output fre-
quency limit. Be sure the system can operate safely at a higher output frequency.
The warning clears when the output drops below the maximum limit.
WARNING/ALARM 65, Control card overtemperature
The cut-out temperature of the control card is 176 °F [80 °C].
Troubleshooting
WARNING 66, Heatsink temperature low
The adjustable frequency drive is too cold to operate. This warning is based on the
temperature sensor in the IGBT module.
Increase the ambient temperature of the unit. Also, a trickle amount of current can
be supplied to the adjustable frequency drive whenever the motor is stopped by
setting 2-00 DC Hold/Preheat Current at 5% and 1-80 Function at Stop.
ALARM 67, Option module configuration has changed
One or more options have either been added or removed since the last power-
down. Check that the configuration change is intentional and reset the unit.
ALARM 69, Power card temperature
The temperature sensor on the power card is either too hot or too cold.

• Check that the ambient operating temperature is within limits.
• Check for clogged filters.
• Check fan operation.
• Check the control card.
