•
Parameter 6-10 Terminal 53 Low Voltage.
•
Parameter 6-12 Terminal 53 Low Current.
–
•
Parameter 6-20 Terminal 54 Low Voltage.
•
Parameter 6-22 Terminal 54 Low Current.

supply voltage. See parameter 14-12 Function at Mains Imbalance.
– DC-link voltage exceeds limit.
– DC-link voltage is lower than voltage warning low-limit.
– More than 100% load for too long.
Motor is overheated due to more than 100% load for too long. See
–
parameter 1-90 Motor Thermal Protection.
Thermistor or thermistor connection is disconnected. See
–
parameter 1-90 Motor Thermal Protection.
X Inverter peak current limit is exceeded.
X Discharge from output phases to ground.
X Short circuit in motor or on motor terminals.
No communication to frequency converter. See parameter group 8-0*

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.
