Micro-Speed® MX-Ultra™ (Traverse Models)
The Ultra™ VFD for travel motion (and other controlled, ramp-to-stop) applications. Ideal for advanced applications with motors 1-600 HP. Models available in all 3-phase voltages (208 – 600V).
Do you have a 1-20 HP traverse application and do not require any of the Ultra™ features? Press this button to view our CXR series.
Available Models by Voltage (Open to View)
All traverse models are pre-programmed for use in a horizontal motion application (ramp-to-stop, controlled deceleration).
