locked Cause of problem
Signal on terminal 53 or 54 is less than 50% of value set in
6-10 Terminal 53 Low Voltage, 6-12 Terminal 53 Low Current,
6-20 Terminal 54 Low Voltage or 6-22 Terminal 54 Low Current. See
X also parameter group 6-0*
Missing phase on supply side or too high voltage imbalance.
X X Check supply voltage. See 14-12 Function at Mains Imbalance
X Internediate circuit voltage exceeds limit.
Intermediate circuit voltage drops below "voltage warning low"
X limit.
X More than 100% load for too long.
Motor is too hot due to more than 100% load for too long. See
X 1-90 Motor Thermal Protection
Thermistor or thermistor connection is disconnected. See
X 1-90 Motor Thermal Protection
X X Inverter peak current limit is exceeded.
X X Discharge from output phases to ground.
X X Short-circuit in motor or on motor terminals.
No communication to frequency converter. See parameter group
X 8-0*
X The fan is not working (Only on 400 V 30-90 kW units).
Motor phase U is missing. Check the phase. See 4-58 Missing Motor
X X Phase Function.
Motor phase V is missing. Check the phase. See 4-58 Missing Motor
X X Phase Function.
Motor phase W is missing. Check the phase. See 4-58 Missing
X X Motor Phase Function.
X X Contact your local Danfoss supplier.
Overload on Terminal 27, Digital Output
Overload on Terminal 29, Digital Output
X X Discharge from output phases to ground.
X X 24 V DC may be overloaded.
X X Control voltage low. Please contact your local Danfoss supplier
X Contact your local Danfoss supplier.
The setting of motor voltage, motor current and motor power is
X presumably wrong. Check the settings.
X The motor current is too low. Check the settings.
X The motor is too big for the AMA to be carried out
X The motor is too small for the AMA to be carried out
