When driving a 400V class motor by the inverter, the motor
must be an insulation-enhanced motor or measures must
be taken to suppress surge voltage. Surge voltage
attributable to the wiring constants may occur at the motor
terminals, deteriorating the insulation of the motor.

When parameter clear or all parameter clear is performed, the
required parameters must be set again before starting
operations because all parameters return to the initial value.
