Troubleshooting
ALARM 57, AMA timeout
Try to start the AMA again a number of times, until the
AMA is carried out. Note that repeated runs may heat the
motor to a level where the resistance R
increased. In most cases, however, this is not critical.
ALARM 58, AMA internal fault
Contact your Danfoss supplier.
WARNING 59, Current limit
The current is higher than the value in
parameter 4-18 Current Limit.
WARNING 60, External interlock
External interlock has been activated. To resume normal
operation, apply 24 V DC to the terminal programmed for
external interlock and reset the frequency converter (via
serial communication, digital I/O, or by pressing [Reset]).
WARNING/ALARM 61, Feedback Error
7 7
An error between calculated speed and speed
measurement from feedback device. The function Warning/
Alarm/Disabling setting is in parameter 4-30 Motor Feedback
Loss Function. Accepted error setting in
parameter 4-31 Motor Feedback Speed Error and the allowed
time the error occur setting in parameter 4-32 Motor
Feedback Loss Timeout. During a commissioning procedure
the function may be effective.
WARNING 62, Output Frequency at Maximum Limit
The output frequency is higher than the value set in
parameter 4-19 Max Output Frequency. This is a warning in
+
VVC mode and an alarm (trip) in Flux mode.
ALARM 63, Mechanical Brake Low
The actual motor current has not exceeded the "release
brake" current within the "Start delay" time window.
WARNING 64, Voltage Limit
The load and speed combination demands a motor
voltage higher than the actual DC link voltage.
WARNING/ALARM/TRIP 65, Control Card Over
Temperature
Control card over temperature: The cut-out temperature of
the control card is 80 °C.
WARNING 66, Heatsink Temperature Low
The heat sink temperature is measured as 0 °C. This could
indicate that the temperature sensor is defect. Thus the fan
speed is increased to the maximum in case the power part
or control card is very hot.
ALARM 67, Option Configuration has Changed
One or more options has either been added or removed
since the last power down.
ALARM 68, Safe Stop
Safe Stop has been activated. To resume normal operation,
apply 24 V DC to T-37. Press [Reset].
WARNING 68, Safe Stop
Safe Stop has been activated. Normal operation is resumed
when Safe Stop is disabled.

AUTOMATIC RESTART
Automatic restart is possible after disabling Safe Stop.
and R are
s r
This can cause the motor to be started, possibly resulting
in death or serious injury.
Make sure, that the motor working area is kept clear.
ALARM 69, Power card temperature
The temperature sensor on the power card is either too
hot or too cold.
ALARM 70, Illegal FC Configuration
Actual combination of control board and power board is
illegal.
WARNING 73, Safe stop auto restart
Safe stopped. Note that with automatic restart enabled,
the motor can start when the fault is cleared.
WARNING 76, Power Unit Setup
The required number of power units does not match the
detected number of active power units.
WARNING 77, Reduced power mode
This warning indicates that the drive is operating in
reduced power mode (that is, less than the allowed
number of inverter sections). This warning generates on
power cycle when the frequency converter is set to run
with fewer inverters and remains on.
ALARM 78, Tracking Error
The difference between set point value and actual value
has exceeded the value in parameter 4-35 Tracking Error.
Disable the function by parameter 4-34 Tracking Error
Function or select an alarm/warning also in
parameter 4-34 Tracking Error Function. Investigate the
mechanics around the load and motor, Check feedback
connections from motor – encoder – to frequency
converter. Select motor feedback function in
parameter 4-30 Motor Feedback Loss Function. Adjust
tracking error band in parameter 4-35 Tracking Error and
parameter 4-37 Tracking Error Ramping.
ALARM 79, Illegal power section configuration
The scaling card is the incorrect part number or not
installed. Also MK102 connector on the power card could
not be installed.
ALARM 80, Drive Initialised to Default Value
Parameter settings are initialised to default setting after a
manual (three-finger) reset.
ALARM 81, CSIV corrupt
CSIV file has syntax errors.
ALARM 82, CSIV parameter error
CSIV failed to initialise a parameter.
ALARM 85, Dang fail PB
Profibus/Profisafe Error.
ALARM 86, Dang fail DI
Sensor Error.
