The SJ100 has extended drive performance to new levels by providing starting torque of 200% or more. The drive also has advanced features such as auto tuning to set motor constants; second motor setting; PID control as standard, 16-stage multi-speed operation; and inrush current protection built in. Other useful benefits from the unit include an intelligent terminal system that allows users to select only the functions needed from a comprehensive set of enhanced functions; and the ability to select fan on or off to give longer cooling fan life.

Equipped with regenerative braking as standard, the SJ100 is ideal for constant torque loads where high torque is needed at low speeds - such as for conveyors, extruders, mixers, lifts and others.

Operation is simple, the only controls being run and stop keys, plus a speed control knob on the main panel, and function, scroll up and down, and store buttons inside the front case. Functions are grouped within the menu systems to enable rapid setting. The intelligent, assignable terminals also allow for remote programming and for downloading programs from a PC or one of Hitachi's remote hand-held programming units.

At the heart of the drive is Hitachi's own ISPM (inverter systems power module) that contains all of the power, logic and protection electronics in a compact monobloc component. This construction provides incredible reliability and has been the major contributor to the miniaturisation of such a powerful range of drives. Additionally, the advanced high volume manufacturing employed in the production of the ISPM brings price benefits to the customer.

The Hitachi SJ100 has been designed as a truly global product and carries all world standards including CE, UL, C-UL and C-Tick. The unit is certificated to comply with both the CE low voltage and EMC directives. Stocks of all sizes from 0.2kW to 2.2kW single phase and 0.4kW to 4.0kW three phase are immediately available.
