Hitachi America, Ltd. has announced two new 100V Class models in their WJ200 series, rated at ½ hp and 1 hp, 100-120 VAC, single-phase input, and 200-240 VAC, 3-phase output.

The WJ200 is a sensorless vector (SLV) drive that is capable of 200% or greater torque across the speed range and has improved speed regulation (the company reports dramatic improvements – fluctuation half that of previous models.)

The WJ200 is feature rich:

Integrated PLC-like functionality: With its powerful Easy Sequence (EzSQ) logic controller function, programs up to 1024 lines can be created on a PC using a structured language editing tool. These programs can then be transferred to the WJ200 to control its operation and allow sophisticated control schemes to be created without the use of external controllers.

One drive for two motor realms: The capability to drive both induction motors and permanent magnet (PM) motors.

EzCOM peer-to-peer communications: One drive is designated as the “administrator,” and controls the network. Other drives on the network can be master or slave, with masters able to write data to any designated slave(s). Master/slave roles are rotated under the control of the administrator automatically. Up to 8 masters can reside on the network, and up to 32 drives (up to 247 drives, if external signal repeaters are used). The administrator can be master or slave also.

The WJ200 also is RoHS compliant. Option boards will be released in the near future to allow communication via Ethernet/IP, DeviceNet, CompoNet, ProfiBus, CANopen, and others.
