ㆍ
In case of driving 400V class motor with the drive, use the motor with reinforced
insulation or conduct suppress measure against micro-surge voltage. (Motor may
be sometimes destroyed upon deteriorated its insulation performance due to
micro-surge voltage.)
ㆍ
In case of initialization of parameters, set up required parameters again before
operation. Parameter initialization changes the parameter values to factory settings.
