Transitioning  to MDrivePlus Microstepping from Legacy MDrive

The MDrivePlus Microstepping (MDM) products represent significant improvements over the legacy MDrives. They feature a broader parameter setup, 20 microstep resolutions, better detectable pulse width as low as 50 nanoseconds, improved current control, programmable filtering and enhanced thermal dissipation. With these many improvements, the MDrivePlus Microstepping are not "drop in replacements" for existing legacy MDMs.

Pictured here, legacy MDM products had a single parameter setup screen using the supplied IMS SPI Motor Interface.

 

MDrivePlus now offers an expanded range of 11 selectable setup parameters with several software screens (shown below) to accommodate the additional parameters. Available paramenters for the MDrivePlus Microstepping (MDM) are compared below with those available for legacy MDrive Microstepping. For more detailed information about various MDrivePlus Microstepping parameter settings, please refer to the applicable manual: MDrive17 & 23 Plus Microstepping, MDrive34Plus Microstepping or MDrive34AC & 42AC Plus Microstepping.
