Transitioning from Legacy MDrive 17 & 23
Speed Control Products
Featuring 1 configurable speed control input
The MDrivePlus Speed Control (MDO) products represent significant improvements over the legacy MDrives. Based on new patented technology, they feature a broader parameter setup, 20 microstep resolutions, higher clock oscillator rate up to 5MHz (from 100 kilohertz), improved current control and enhanced thermal dissipation. With these many improvements, the MDrivePlus Speed Control are not "drop in replacements" for existing legacy MDOs.
Now available as Plus or Plus2 versions:
- Plus2 version
currently available for size 34 products as well as the MForce PowerDrive. See details.- Plus version
currently available for size 17 & 23 products — detailed below on this page, as well as the
MForce MicroDrive.
A single Graphical User Interface (GUI), SPI Motor Interface beginning with version 3.1.37, will set parameters for ALL Speed Control products - MDrive and MForce, Plus and Plus2. The GUI automatically detects the connected product and enables the appropriate features available for that product.
Pictured here, legacy MDO products had a single parameter setup screen using the supplied IMS SPI Motor Interface.
MDrivePlus now offers an expanded range of 17 selectable setup parameters with several software screens (shown below) to accommodate the additional parameters. Available paramenters for the MDrivePlus Speed Control (MDO) are compared below with those available for legacy MDrive Speed Control. For more detailed information about various MDrivePlus Speed Control parameter settings, please see the manual.

Optional Parameter Setup Cable
The optional 12' (3.6m) parameter setup cable part number MD-CC300-000 facilitates communications wiring and is recommended with all first orders. It connects an MDrive's P2 Connector to a PC's USB port. MDrives with 10-pin friction lock wire crimp also require adapter MD-ADP-H.
Older MD-CC300-000 cables may or may not function on some computers with new MDrivePlus Speed Control (MDO) units. Customers having difficulty connecting one of these cables to an MDrivePlus Speed Control unit should return the cable to IMS Schneider Electric Motion USA for a firmware upgrade at no cost except for shipping. Please use the RMA Request Form to provide IMS with information on the item(s) you are returning.
Newer MD-CC300-000 cables have a "V1.3" sticker on them identifying the current firmware, and will not have an issue with compatibility.
For complete optional parameter setup cable details and parts information, see Cables and Cordsets.
