Table 6.2 Warnings and Alarms Code List
1) These faults may be caused by mains distortions. Installing a Danfoss line filter may rectify this problem.
2) For enclosure size J7, the warning can also be caused by high UDC voltage.

Cause
24 V DC may be overloaded.
–
Wrong setting for motor voltage and/or motor current.
Motor current is too low. Check the settings.
The power size of the motor is too large for the AMA to
operate.
The power size of the motor is too small for the AMA to
operate.
The parameter values of the motor are outside of the
acceptable range. AMA does not run.
The AMA is interrupted.
–
Contact Danfoss.
Frequency converter overload.
–
–
Actual motor current has not exceeded release brake
current within start delay time window.
The cutout temperature of the control card is 80 °C
(176 °F).
–
–
All parameter settings are initialized to default settings.
Occurs in IT mains when the frequency converter coasts
and the DC voltage are higher than 830 V. Energy on DC-
link is consumed by the motor. This function can be
enabled/disabled in parameter 0-07 Auto DC Braking.
A feedback fault is detected by option B.

–
Try to start PM motor which is rotating in an abnormal
high speed.
