WEG introduces decentralised low-power variable-speed drivesWEG is launching new MW500 series variable-speed drives (VSDs) for decentralised installation with low-power induction motors rated from 370-550W.

The robust and durable MW500 supports both voltage vector control (VVW) and V/f characteristic curve control. It can handle an overload of 150 per cent for 60s every 10min and can be deployed at ambient temperatures of up to 40degC when wall-mounted or 50degC if installed directly on a motor.

A sturdy housing design with protection to IP66 or NEMA 4X allows the VSDs to be mounted directly on the motor terminal box or on the wall using an adapter plate. This eliminates the need for a motor feed cable and switch cabinet, enabling users to install the MW500 close to the controlled motor to improve deployment flexibility.

Built-in control

The standard version of the MW500 comes with a PID process controller and an integrated PLC with numerous programming functions. The device includes an EMC filter compliant with EN 61800-3. An analogue speed control potentiometer is also included in the drive to enable the induction motor speed to be set without the need for a control panel.

To ensure flexibility, digital I/O and communication protocols such as CANopen, DeviceNet and Profibus DP are available for the MW500 as optional extension modules. The Windows-based SuperdriveG2 application software for programming, controlling and monitoring the MW500 is available to customers on the WEG website as a free download.

Johannes Schwenger, head of product management low- and medium-voltage drive systems Europe at WEG, explains: "The compactness and flexibility of the decentralised MW500 VSDs allow users to install them exactly where they are needed. The new frame size extends our successful drive product line with a flexible and durable solution for low power levels."
