Description and solution
Occurs when the motor speed exceeds 1,650 rpm (on an 1,800
rpm motor) during stator inductance tuning, or when the inverter
fails to detect the stator inductance for a long time. Check the
motor pole number and the wiring condition between the
inverter and the motor.
Occurs if the motor time constant is set too long at PAR_52
during a rotor time constant tuning. Decrease the value at
PAR_53 by 30% and try again.
Occurs if the motor time constant is set too short at PAR_53
during a rotor time constant tuning. Increase the value at
PAR_53 by 30% and try again.
Occurs when the detected synchronous motor stator resistance
is out of the normal range of 0.002 –
10Ω. Check the wiring
between the inverter and the motor, or check if the motor has
not been burnt.
This error may occur when the motor capacity is too small for
the inverter.
