WJ200-040HF Hitachi 5.0HP 9.2A Three Phase 380-480V Inverter
The WJ200-040HF is a legacy product and although still available it is not recommended for new designs. The WJ200 series has been superceded by the WJ-C1. Retrofitting is simplified as the WJ-C1 has the same footprint, and settings can be copied from the WJ200 to the WJ-C1.
The WJ200-040HF is a 5.0HP ac drive from the Hitachi WJ200 series, with a rated output of 9.2A for constant torque applications running from a 380-480V Three Phase supply. The WJ200-040HF can also be used with a 7.5HP or 11.1A motor in variable torque application such as centrifugal fans and pumps.
The WJ200-040HF features advanced sensorless vector control with a high starting torque of up to 200% and dramatically improved speed stability. A brake chopper is included as standard in all models as is the integral keypad, although an enhanced keypad or programming via the built in USB interface is also available.
Side by side mounting is possible to save panel space, and further space and cost savings can be achieved removing external equipment by utilizing features such as the safe-stop and Easy Sequence (EzSQ) which allows PLC like functionality.
The WJ200-040HF is capable of driving both standard induction motors and permanent magnet (PMAC) motors.
The WJ200 is designed to be low maintenance, with DC bus capacitors and fans having a design lifetime of 10 years, and screwless spring loaded terminals don't just make installation simple, they also don't need tightening during service.
Modbus communication is built in as standard, however option cards can add a number of different fieldbus protocols, along with EzCom peer to peer communications between drives being possible, with 1 drive acting as administrator and the others as master or slave.
