6) Motor generates abnormal heat
7) Motor runs inversely against direction reference
Phase sequence of main circuit wiring (U, V, W) between inverter and motor does not match in
sensorless control.
Or, function data for speed reference are incorrect.
Motor generates
abnormal heat.
Use motor dedicated
to inverter.
NO
NO
Decrease load or
increase inverter or
motor capacity.
YES
Motor fault is
suspected.
Inverter fault is
suspected.
Contact FUJI.
NO
Change data of
function code P02
to match.
Execute motor
parameter tuning
(function code H01).
YES
NO
YES
YES
NO
NO
NO
YES
Do motor parameters
(function code P and A)
match companion motor?
Does motor operate at very
low speed continuously?
Is motor dedicated to
inverter?
Is load too heavy?
Is inverter output voltage
(U, V, W) balanced?
Is motor dedicated to
VG7?
