3) Motor stalls during acceleration
4) Motor generates abnormal heat
Motor stalls during
acceleration.
Increase
acceleration time.
YES
Reduce moment of
inertia of load.
Or, increase inverter
capacity.
Inverter fault or
malfunction due to
noise is suspected.
Contact FUJI.
Contact FUJI.
Use thicker wiring
between inverter
and motor.
Or, shorten wiring length.
Decrease load torque.
Or, increase inverter
capacity.
YES
YES
YES
Increase torque boost.
NO
NO
NO
NO
YES
YES
NO
NO
Is acceleration time
(function code F07,
C46, C56 or C66)
short?
Is moment of inertia
of motor or load
large?
Does motor terminal
voltage drop?
Is load torque large?
Is correct torque
boost (function code
A46) specified?
Do you use special-
purpose motor?
Motor generates
abnormal heat.
Decrease torque
boost value.
NO
Use motor dedicated
to inverter.
Decrease load or
increase motor
capacity.
Motor is defective.
Inverter fault or
malfunction due to
noise is suspected.
Contact FUJI.
YES
YES

NO
NO
YES
Is torque boost too
large?
Does motor operate
at very low speed
continuously?
Is load too heavy?
Is inverter output
voltage (U, V, W)
balanced?
