Trip lock Cause of problem
The terminal 27 is overloaded or short circuited to earth.
The terminal 29 is overloaded or short circuited to earth.
Discharge from output phases to ground, using the value of 15–31
X
Alarm Log Value if possible.
The supply on the power card is out of range. Contact the local
X
Danfoss supplier.
X 24 V DC is possibly overloaded.
The setting of motor voltage, motor current, and motor power is
presumably wrong. Check the settings.
The motor current is too low. Check the settings.
The motor is too large to perform AMA.
The motor is too small to perform AMA.
The parameter values found from the motor are outside acceptable
range
The user has interrrupted the AMA.
Try to start the AMA again a number of times, until the AMA is
complete.
NOTICE
Repeated runs can heat the motor to a level where the
resistance Rs and Rr are increased. In most cases, however,
this is not critical
Contact the local Danfoss supplier.
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 external interlock and
reset the frequency converter. Reset via serial communication, digital
I/O, or [Reset] on the LCP).
The minimum required current for opening the mechanical brake has
not been reached.
The temperature sensor on the power card is either too hot or too
X
cold.
All parameter settings are initialised to default settings.
The frequency converter is auto DC braking
Torque is below the torque level set for no load, indicating a broken
belt. See parameter group 22-6* Broken Belt Detection.
The drive detected a locked rotor situation. See 30-22 Locked Rotor
Protection and 30-23 Locked Rotor Detection Time [s].
Flow/pressure information is missing
High back-emf voltage. Stop the rotor of the PM motor.
Fire mode has been activated
Fire Mode has suppressed one or more warranty voiding alarms
