The WJ200 inverter can be used to drive both induction motors (IM) and permanent magnetic motors (PM).
PM motors are energy efficient and make effective use of available space.
WJ200 can be used for both heavy and normal duty. One- frame-size smaller WJ200 can be applicable to certain applications.
The WJ200 inverter has a password function to prevent changing parameters or to hide some or all parameters.
Design lifetime 10 Years or more* for DC bus capacitors and cooling fan.Cooling fan ON/OFF control function for longer fan life.
WJ200 diagnoses lifetime of DC bus capacitors and cooling fan(s).
Hitachi original PWM control method limits motor terminal voltage to less than twice inverter DC bus voltage.
( During regeneration, the motor terminal voltage may exceed the motor maximum insulation voltage.)
