Frequency Inverter, ACU 8

Bonfiglioli Riduttori S.p.A., a global designer and manufacturer of gearmotors, drive systems and planetary gearboxes, has announced a new Frequency Inverter series, the ACU8 Cabinet Solution, which expands its drive portfolio. Specially designed to meet the customer requirements with a wide range of options, such as PLC functions and feedback sensors, ACU 8 Cabinet solution can be flexibly integrated into any automation process by using either standard control mode or bus communication protocols. The liquid cooled version does not require a large cooling fan, which makes the ACU 8 suitable for heavy industries with harsh environments in industries like mining, metals and paper. This 6 phase/12 pulse compact drive brings benefits such as cost effectiveness and energy saving by reducing harmonics distortion. With a high degree of protection (IP54), these compact devices can be installed almost anywhere in the plant. The ACU 8 parallel connection (modular system above 400 kW) is well optimised by synchronising AC output current with a view to not using any output filters. ACU 8 series also offers the ‘Must’ by controlling either Induction or PM (permanent magnet) motors in sensorless or closed loop control.
