Hitachi Introduces New Advanced AC Micro Drives
Hitachi America, Ltd., Industrial Components & Equipment Division, today announced the new WJ200 series of inverters. This new model advances the benchmark for performance and functionality in micro-size AC drives. The WJ200 is a sensorless vector (SLV) drive capable of 200% or greater torque across the speed range. Speed regulation at low speed is dramatically improved – fluctuation is half that of previous models. Improved trip avoidance measures have been incorporated for unsurpassed system reliability and availability. The WJ200 offers PLC-like functionality by means of the integrated Easy Sequence (EzSQ) programming function. Programs up to 1024 lines can be created on a PC using this structured language tool, and can then be transferred to the WJ200. In this way, very sophisticated control schemes can be created without the use of external controllers. Simple position control applications are also possible with the WJ200 utilizing the integrate
