The MDrivePlus products represent significant improvements over the legacy MDrives. Along with these improvements, there may be situations where the MDrivePlus are not "drop in replacements" for existing legacy MDrives:  

— MDrivePlus Microstepping Transition from Legacy
— MDrivePlus Motion Control Transition from Legacy
— MDrivePlus Speed Control Transition from Legacy
        •    Plus [MDrive17 & 23]
        •    Plus2 [MDrive34]

Through customer feedback, IMS determined that potential ground loops could be introduced in MD-CC400-000 and MD-CC300-000 cables used with MDrivePlus and MForce products, and has released electrically isolated Communication Converters to improve field reliability.

MDrive Motion Control (MDI) units, when used in the Party Mode (RS422/485 Multidrop,) may have unwanted circulating currents in the common wire of the communication port. These unwanted currents may cause hardware failures or communication errors.    [read more]

Pneumatic cylinders are frequently used for simple stroke limited or cut-to-length applications because of low cost and simplicity. Air cylinders may sometimes be an acceptable solution, but they are not always the best.    [read more]

At times a Motion Control MDrive will fail to respond to serial communications because it has been set to work in party mode, checksum mode or both. A simple solution is to issue a string to the drive that will result in resetting it to factory defaults. To do this, the string "FD" is sent in various formats to satisfy party mode and checksum filtering.    [read more]
