General-purpose drives reach their third generation

04 December, 2014

At the recent SPS IPC Drives show in Germany, the Welsh drives-maker Invertek unveiled the third generation of its general-purpose Optidrive family of drives. Available in four frame sizes covering ratings from 0.37–22kW, the Optidrive E3 can control IE2, IE3 and IE4 permanent magnet and synchronous reluctance motors.

The sensorless vector drives are said to offer high reliability, easy installation, precise motor control and energy saving, and are compatible with supply voltages around the world. With only 14 basic parameters – and fewer than 60 in total – setting up the drive for a wide range of applications is said to be straightforward.

The drives are available in IP20 and IP66 versions and can be mounted directly onto machines and specified with an isolator / disconnect switch if required. They can switch between industrial mode and fan or pump mode at the touch of a button.

“Optidrive general-purpose drives have established a world-wide reputation for offering precise motor control that’s really simple to install and commission,” says Invertek’s r&d director, David Jones. “E3 takes this ethos one step further and we’re confident that our customers around the world will be impressed with the result.”

The drives can be mounted on a Din-rail or using a simple keyhole. The power supply is connected at the top and the motor supply at the base. Easy-to-use 5mm rising clamp terminals simplify wiring.

EMC filters and brake choppers are built in, while Modbus RTU and CANopen communications are standard. The drives offer dual analogue inputs, internal PI control and Bluetooth connections.
