The user has interrupted the AMA.
Restart the AMA some times, until the AMA is complete.
NOTICE
Repeated runs can heat the motor to a level where the
resistance R and R are increased. Usually, however, this
s r
increased resistance is not critical.
Contact the local Danfoss supplier.
The current is higher than the value in parameter 4-18 Current Limit.
External interlock is 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 heat sink temperature is measured as 0 °C. This result could
indicate that the temperature sensor is defect. The defect causes the
fan speed to increase to its maximum to cool down the power part or
control card.
–
The temperature sensor on the power card is either too hot or too
cold.
Power size configuration fault on the power card.
All parameter settings are initialized 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 frequency converter detected a locked rotor situation. See
parameter 30–22 Locked Rotor Protection and parameter 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 is activated.
Fire mode has suppressed 1 or more warranty voiding alarms.
