MS300 is an efficient and stable frequency inverter that supports both IM and PM motors

The MS300 series supports both IM and PM motor control for application flexibility and provides Safe Torque Off (STO) safety mechanism. With a drive size reduced up to 40% the MS300 series save space. It reduces time for setup and wiring, while providing high efficiency and stability.

Various essential functions and features are built-in, including:

  • Safe Torque Off function (STO)
  • PLC capacity for simple programming needs
  • A communication slot for various communication cards
  • Removable Keypad which supports remote operation away from drive
  • Built-in USB port for easy and fast programming setting, update and real-time monitoring and tuning
  • Removable fan - easy to replace and maintain for a longer lifetime
  • Removable RFI Jumper applicable for different application needs
  • Supports side-by-side installation, with operating temperatures of -20˚C ~ 40˚C, which enables highly flexible and efficient installation.
