Available for operating induction motors with low power in the range of 370 to 550W, the VSDs support both voltage vector control and V/f characteristic curve control and offers a robust and durable solution. The VSD can handle an overload of 150 per cent for 60 seconds every ten minutes and can be deployed at ambient temperatures up to 40°C wall mounting or 50°C for motor mounting.
A sturdy housing design rated 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, allowing users to install the MW500 close to the controlled motor, increasing deployment flexibility. 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 setting the speed of an induction motor without the need for a control panel if desired. Digital I/O and communication protocols such as CANopen, DeviceNet and Profibus DP are available for the MW500 as optional extension modules. A free Windows-based application software, SuperdriveG2, enables programming, control and monitoring of the VSDs.
