Trip Cause of problem
locked
X The motor current is too low. Check the settings.
X The motor is too big to perform AMA.
X The motor is too small to perform AMA.
The parameter values found from the motor are outside
X
acceptable range
X The AMA has been interrupted by the user
Try to start the AMA again a number of times, until the AMA
is carried out.
NOTICE
Repeated runs may heat the motor to a level where
X
the resistance Rs and Rr are increased. In most cases,
however, this is not critical
X X Contact the local Danfoss supplier.
X The current is higher than the value in 4-18 Current Limit
External interlock has been activated. To resume normal
operation, apply 24 V DC to the terminal programmed for
X external interlock and reset the frequency converter (via
serial communication, digital I/O, or by pressing reset button
on keypad).
This warning is based on the temperature sensor in the IGBT
X
module (Only on 400 V 30-90 kW units).
The temperature sensor on the power card is either too hot
X X X
or too cold.
X X
Internal fault. Contact the local Danfoss supplier.
X All parameter settings are initialized to default settings.
X The drive is auto DC braking
Torque is below the torque level set for no load, indicating a
X X
broken belt. See parameter group 22-6* Broken Belt Detection.
X High back-emf voltage. Stop the rotor of the PM motor.
X Fire mode has been activated
Fire Mode has suppressed one or more warranty voiding
X
alarms
The power or switch mode power supply has been
X X exchanged. (Only on 400 V 30-90 kW units). Contact the local
Danfoss supplier
The frequency converter has a new type code (Only on 400 V
X X
30-90 kW units). Contact the local Danfoss supplier.
