Kit cabling varies with MDrivePlus ordered.

 

All-inclusive QuickStart Kits facilitate rapid design verification by bundling MDrive products with everything needed to connect quickly and conveniently, enabling engineers to confirm with confidence that their application’s design goals are met.

QuickStart Kits include: a single sheet instruction guide, software/manuals CD, and connection cabling including Communications Converter and Prototype Development Cable(s).

Order QuickStart Kits simply by placing a “K” at the beginning of an MDrive part number.

Connecting an MDrive has never been easier with readily available Communications Converters and Prototype Development Cables, in addition to Mating Connector Kits for use in building your own cables. Select the “Connectivity solutions” tab above for details on these connectivity options.

 

Encoder

The internal encoder option is a differential magnetic encoder: The internal magnetic encoder offers several key advantages:

  1. Smaller footprint to the MDrive than an externally mounted encoder.
  2. Available line counts: 100, 200, 250, 256, 400, 500, 512, 800, 1000.
  3. Encoder in a closed environment, limited susceptibilty to dust contamination.
  4. Robust output sink current of 20 mA.
  5. May be connected as single-end or differential.
  6. Encoder interfaces via connector P4, a 10-pin locking wire crimp. Avaialble connectivity accessories

Communications Converters

Encoder

The internal encoder option is a 512-line (2048 count) differential magnetic encoder: The internal magnetic encoder offers two key advantages:

  1. Reduced connections externally, thus reduced system cabling, as encoder feedback is all internal to the MDrivePlus.
  2. Smaller footprint to the MDrivePlus than an externally mounted encoder.
