VF (Inverter) Control

50% Energy Savings

VF (inverter) control is the result of the latest power electronics technology, Power consumption and the capacity of power supply facilities can be cut in half (compared to previous Hitachi models)thanks to this remark able new method (see figure below).

Ultra-smooth Riding Comfort

The inverter control system makes elevator movement smoother than ever before and provides high landing accuracy(see figure below).



Double Safety

Two microcomputers allocate and manage elevator operating functions and, by diagnosing each other, ensure optimum functionability.


Operational programming of the microcomputers can be changed at the site with relative ease using this EEPROM(Electrically Erasable Programmable Read-Only Memory). This easy programmability allows you to change elevator operating schedules for non-stop floors, homing floors, etc., according to the elevator use patterns of the building occupants.

Digital Floor Controller

The microcomputers detect the elevator car position by counting the pulses generated from the speed generator(rotary encoder)which is coupled with the traction motor.

Multiplex Transmission

Microcomputers connected by SCL (Serial Communication Link) are located in the car, on each floor and in the machine room, This enables the system to be flexibly expanded.
