NEW BENCHMARK STANDARD FOR MICRODRIVES
August 2004

Silverteam has set a new benchmark standard for microdrives with the launch of the Hitachi SJ200 series. Highly compact and extremely powerful, without compromising on ease of use, the SJ200 is the first product to feature Hitachi’s new iSLV (intelligent sensorless vector control) technology for dramatically improved performance.

With iSLV, the usual long and complicated auto-tuning process is no longer required to achieve optimal performance. Straight out of the box, the SJ200 will provide high starting of 200% or greater at 1Hz without motor tuning. The drive also provides an advanced over-current trip avoidance function for acceleration, and over-voltage trip avoidance for deceleration. Eliminating these typical nuisance trips means improved system reliability, and ultimately increased machine availability.

Further advanced features include improved PID control, while embedded PLC functionality enables output terminals to be assigned logic functions, and ON and OFF delay times to be set for each output terminal. In addition, the SJ200 provides analogue setpoint maths functions, all providing a more flexible system design.

Other useful features include an in-built EMC filter, side-by-side mounting capability, and a digital keypad that can be removed and remotely mounted. The SJ200 also features a removable terminal connector for reduced wiring effort and simplified field maintenance.

The SJ200 is approved to a wide range of global standards, including CE, UL, c-UL and c-Tick, allowing it to be used anywhere in the world.
