Troubleshooting
ALARM 54, AMA motor too small
The motor is too small for the AMA to operate.
ALARM 55, AMA parameter out of range
The parameter values of the motor are outside of the
acceptable range. The AMA does not run.
ALARM 56, AMA interrupted by user
The AMA is manually interrupted.
ALARM 57, AMA internal fault
Try to restart the AMA again. Repeated restarts can
overheat the motor.
ALARM 58, Internal fault
Contact a Danfoss supplier.
WARNING 59, Current limit
The current is higher than the value in
parameter 4-18 Current Limit.
Troubleshooting
•
Ensure that motor data in parameters 1-20 to 1-25
is set correctly.
•
Possibly increase the current limit.
•
Be sure that the system can operate safely at a
higher limit.
ALARM 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.
Troubleshooting
•
Clear the external fault condition.
•
To resume normal operation, apply 24 V DC to
the terminal programmed for external interlock.
•
Reset the frequency converter.
WARNING/ALARM 61, Feedback error
An error between calculated speed and speed
measurement from feedback device.
Troubleshooting
•
Check the settings for warning/alarm/disabling in
parameter 4-30 Motor Feedback Loss Function.
•
Set the tolerable error in parameter 4-31 Motor
Feedback Speed Error.
•
Set the tolerable feedback loss time in
parameter 4-32 Motor Feedback Loss Timeout.
ALARM 63, Mechanical brake low
The actual motor current has not exceeded the release
brake current within the start delay time window.

WARNING/ALARM 65, Control card over temperature
The cutout temperature of the control card has exceeded
the upper limit.

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 68, Safe stop activated
Safe Torque Off (STO) is activated. If STO is in manual
restart mode (default), to resume normal operation, apply
24 V DC to terminals 37 and 38 and initiate a reset signal
(via fieldbus, digital I/O, or [Reset]/[Off Reset] key). If STO is
in automatic restart mode, applying 24 V DC to terminals
37 and 38 automatically resumes the frequency converter
to normal operation.
ALARM 69, Power card temperaturePower card
temperature
The cutout temperature of the power card has exceeded
the upper limit.

ALARM 80, Drive initialised to default value
Parameter settings are initialized to default settings after a
manual reset.

WARNING 87, Auto DC-Braking
Occurs in IT mains when the frequency converter coasts,
and the DC voltage is higher than 830 V for 400 V units
and 425 V for 200 V units. The motor consumes energy on
the DC link. This function can be enabled/disabled in
parameter 0-07 Auto DC Braking.
ALARM 88, Option detection
A new option configuration has been detected. Set
parameter 14-89 Option Detection to [1] Enable Option
Change, and power cycle the frequency converter to
accept the new configuration.
ALARM 95, Broken belt
Torque is below the torque level set for no load, indicating
a broken belt. Parameter 22-60 Broken Belt Function is set
for alarm.
