QuickStart Kit
quickstart thumbnail

All-inclusive QuickStart Kits facilitate rapid design verification by bundling any one of over 156,000 MDrivePlus products -- built to your specifications -- 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 connecting cabling including Communications Converter and Prototype Development Cable(s).

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

Above photo represents a QuickStart Kit. Kit cabling varies with MDrivePlus ordered.

TO VIEW complete QuickStart Kit components list by MDrivePlus Part #: Interactive MDrivePlus Part Builder.

CONNECTIVITY NOTE: Communications Converters and Prototype Development Cables, in addition to Mating Connector Kits for use in building your own cables, are available separately. Refer to the following section for more complete details.

  • Comm Converters
  • Prototype Development Cables
  • Mating Connector Kits

Electrically Isolated, in-line converters pre-wired with mating connectors to conveniently set parameters and program a single MDrivePlus via a PC USB port.

To view connectivity options for each model MDrive, select from the drop-down listing above.

Converter Part Number Mating Connector Type
MD-CC301-001 (USB to SPI) 19-Pin M23 Male

 

If building your own cabling, you will need:

  • SPI inline converter or PC parallel port
  • Cabling with appropriate mating connectors for the MDrive model selected

Prototype development cables are designed to speed test/development with pre-wired mating connectors that have flying leads other end. No prototype development cables are available for the MDrivePlus using the 12' Flying Leads or Pluggable Clamp Terminal Strip.

To view connectivity options for each model MDrive, select from the drop-down listing above.

Prototype Development Cable P/N Mating Connector Type Signal Type
MD-CS100-000 19-Pin Circular (Straight) I/O and Communications
MD-CS101-000 19-Pin Circular (Right-Angle) I/Oand Communications
MD-CS-200-000 3-Pin Euro-AC (Straight) Power
MD-CS-201-000 3-Pin Euro-AC (Right-Angle) Power

These Prototype Development Cables will ONLY be used if you are using your own SPI communications converter.

 

If building your own cabling, you will need:

  • Appropriate mating connector and crimp pins if required (Mating connector kits are available for Locking Wire Crimp style connectors)
  • Crimp tooling (Locking Wire Crimp)
  • Shielded twisted pair cabling

There are no mating connector kits available for this product.

Options

Linear Slide

Linear Actuator

Encoders

  • Internal Magnetic Encoder
  • External Optical 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: 512.
  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.
Not available for this product.
