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 cut-out temperature of the control card is 80 °C.
A new option is detected or a mounted option is
removed.
All parameter settings are initialised to default settings.
Occurs in IT mains when the frequency converter coasts
and the DC voltage is 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.
The option is removed successfully.
A feedback fault is detected by option B.
Parameter can only be changed when the motor is
stopped.
Occurs when using a wrong password for changing a
password-protected parameter.
