Motor Control Solutions for Industrial and Material Handling Equipment
Includes Ultra® Features! For use in hoisting applications to control hoisting/lifting motions without a mechanical load brake (requires an encoder for closed-loop control) up to 300 HP at 575V (285 A max). (Replaces MMV30057H models).
NOTE: Add one of the resistors and an encoder option listed above to your quote request (BOTH ARE REQUIRED) unless these items are already installed in your application.
The Micro-Speed® MV-Ultra® models are closed-loop vector drives generally used in hoisting/lifting applications without a mechanical load brake, and for travel motions** requiring precise speed control of up to 6000:1. They use encoder feedback for vector motor control, hoist safety routines, and precise speed control. Models are available in sizes ranging from 1-600 HP (up to 1200 HP with Power Pairing™) and with all 3-phase voltages.
Designed and manufactured in the United States for the crane, lifting, hoisting industries, and many other industrial applications. The Ultra® series is the latest brand of proven variable frequency drives from Power Electronics® International, Inc.® The line combines our highly reliable power sections and instant Gang-Set® programming of the Micro-Speed® line with the latest in easy-to-use web-based programming and communications.
Certification
If you have a traverse application that requires ultra-precise positioning (and are NOT using servo-type motors), this unit can be purchased as a travel model.
A traverse version of this unit removes the “H” suffix from the model number, and travel parameters will be pre-programmed into the unit. Also, a travel-sized resistor should be used instead of a hoist model as shown on this page.
To request a travel version of this drive, simply let us know that the unit will be used in a traverse application when requesting your quote.
Would you like this product installed in an electrical enclosure or control panel?
All Ultra® models have unlockable Advanced Crane Control Options (PE® SAM™ Swing-Amplitude Manager and PE360™ Anti-Twist for under-hook rotation applications)
Would your application benefit from remote (including wireless) programming and/or data logging capabilities? Or will your project have several Ultra® VFDs that you would like to control with just one interface?
If you are interested in any (or all!) of these features, let us know when you request your quote and we can provide you with options!
Does your hoist have a separate mechanical load brake (or a self-locking worm gear)? Use the comparable MX-Ultra® (Open-Loop) model instead.
Do you have a conical rotor-style hoist motor? View our conical rotor MMV-CRH™ models.
Add heavy-duty conformal coating to provide extra environmental protection for this unit:
