MS300: compact, advanced and cost-attractive drive

The MS300 series is perfect for Delta 's integrated factory system with EtherNet/IP communication. Its compact design with up to 40 per cent size reduction, provides open or closed loop control for both IM and PM motors up to 1500Hz. The MS300 series supports control over EtherNet/IP, E-Stop & STO safety and includes a fast deceleration feature with reduced regeneration energy.

Delta's MS300 series is a standard compact vector control drive that inherits Delta's superior drive technology. It supports both IM and PM motor control for application flexibility and provides STO safety (SIL2/PLd). Several essential built-in functions include a PLC for simple programming tasks, a communication slot for various communication cards, and a USB port to enable fast and straightforward data upload and download. With drive size reduced up to 40 per cent, its space saving design helps minimize setup and wiring time, whilst providing a high efficiency and high stability system. Designed for micro variable frequency drive applications up to 22kW, the MS300 delivers high speed up to 1500Hz and operation for either induction motors or permanent magnet motors.

All drives are physically compact - up to 40 per cent smaller than similar models with the same power rating - and deliver high-speed start-up plus fast acceleration and deceleration. All drives are also equipped with brake choppers.

Built to be highly reliable, 100 per cent coated printed circuits boards allow these new drives to withstand dusty and harsh environments for longer periods. New PCB coating for circuit (IEC 60721-3-3 class 3C2) and thermal design applications enable a temperature range from -20 to +50degC. Like its predecessors, the MS300 benefits from Delta's optimised high-range production quality systems enabling this drive to differentiate itself both for reliability and costs.

As well as impressive speed, power and compact size, these drives were specifically designed to be exceptionally user friendly. In addition, all the drive parameters match those of Delta's VFD-C2000 general-purpose drive, making the entire product line easily scalable from a few watts to 22kW. The MS300 offers two control methods - volts per frequency(V/Hz) and sensorless vector control (SVC) .

For communications, the MS300 has a standard modbus and a single option card slot for CANopen, DeviceNet, EtherNet/IP, Modbus TCP, and Profibus-DP. The high-performance MH300 series has two option card slots for increased versatility and features built-in Modbus and CANopen with the same communication option cards as MS300 plus EtherCAT.

The MS300 can control up to four motors simultaneously, it also features a built-in PLC (2K/5ksteps) and Safe-Torque-Off. Other standard features include energy saving modes with network expansion covering EtherNet/IP, Profibus, DeviceNet and Modbus TCP.

Main applications are machine tools, textile machines, woodworking machines, packaging machines, electronics manufacturing, fans, pumps, air compressors and more. Go to www.deltaww.com to learn more about the new MS300 series compact vector drive range.
