Complies with European regulation that limt the use of specific hazardous substances (RoHS)
These inverters are gentle on the environment.
Use of 6 hazardous substances is limited. (Products manufactured beginning in the autumn of 2005 will comply with European regulations (except for interior soldering in the power module.))
Lead, Mercury, Cadmium, Hexavalent Chromium, Polybrominated biphenyl (PBB), Polybrominated diphenyl ether (PBDE)
The Directive 2002/95/EC, promulgated by the European Parliament and European Council, limits the use of specific hazardous substances included in electrical and electronic devices.
The design life of each internal component with limited life has been extended to 10 years.
This helps to extend the maintenance cycle for your equipment
Noise is reduced by the built-in EMC filter
Use of a built-in EMC filter that reduces noise generated by the inverter makes it possible to reduce the effect on peripheral equipment.
Through "slip compensation control" + "voltage tuning," speed control accuracy at low speeds is improved. This minimizes variations in speed control accuracy at times when the load varies, and since the time at creep speeds is shortened, single cycle tact times can be shortened.
Previous energy saving operation functions worked only to control the motor's loss to keep it at a minimum in accordance with the load condition. In the newly developed FRENIC-Multi Series, the focus has been switched away from the motor alone to both the motor and the inverter as electrical products. As a result, we incorporated a new control system (optimum and minimum power control) that minimizes the power consumed by the inverter itself (inverter loss) and the loss of the motor.
