Wiring
CAUTION:
E
● Do not install assemblies or components (e. g. power factor correction capacitors) on the
inverter output side, which are not approved from Mitsubishi. These devices on the inverter
output side may be overheated or burn out.
● The direction of rotation of the motor corresponds to the direction of rotation commands
(STF/STR) only if the phase sequence (U, V, W) is maintained.
● PM motor terminals (U, V, W) hold high-voltage while the PM motor is running even after the
power is turned OFF. Before wiring, the PM motor must be confirmed to be stopped. Other-
wise you may get an electric shock.
● Never connect an PM motor to the commercial power supply.
Applying the commercial power supply to input terminals (U,V, W) of a PM motor will burn
the PM motor. The PM motor must be connected with the output terminals (U, V, W) of the
inverter.
Test operation and adjustment
CAUTION:
E
● Before starting operation, confirm and adjust the parameters. A failure to do so may cause
some machines to make unexpected motions.
