 Above photo represents a QuickStart Kit.
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. |
Internal encoder
The internal encoder option is a 512-line (2048 count) differential magnetic encoder. The internal magnetic encoder offers two key advantages:
- Reduced connections externally, thus reduced system cabling, as encoder feedback is all internal to the MDrivePlus.
- Smaller footprint to the MDrivePlus than an externally mounted encoder.
Remote encoder interface
The remote encoder option, while adding additional wiring to the MDrivePlus, offers two key advantages:
- The user can choose the type of encoder and line count.
- The encoder may be placed directly on the load rather than at the encoder shaft.
Note: The remote encoder interface reduces the number of available I/O points from 8 to 4. General purpose I/O 9-12 and Step and Direction I/O are replaced by differential encoder inputs.
Planetary gearbox
Efficient, low maintenance Planetary Gearbox come fully assembled with the MDrive34Plus and are offered in a large number of reduction ratios in 1-, 2- and 3-stage configurations.

NOTE: To view specific connectivity options for a particular MDrive model, see Connector options by P/N tab above.
Communications Converters
Electrically Isolated, in-line converters pre-wired with mating connectors to conveniently set parameters and program a single MDrivePlus via a PC USB port.

| MD-CC500-000 (CANopen) | Interface cable required - view details |
If building your own cabling, you will need:
- RS-422/485 inline converter or PC card
- Cabling with appropriate mating connectors for the MDrive model selected
- For information on Party Mode (Multidrop) communications view the product manual
Prototype Development Cables
Prototype development cables are designed to speed test/development with pre-wired mating connectors that have flying leads other end.
| Prototype Development Cable P/N | Mating Connector Type | Signal Type |
| MD-CS100-000 | 19-Pin Circular (Straight) | I/O |
| MD-CS101-000 | 19-Pin Circular (Right-Angle) | I/O |
| MD-CS-200-000 | 3-Pin Euro-AC (Straight) | Power |
| MD-CS-201-000 | 3-Pin Euro-AC (Right-Angle) | Power |
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)
- Field Solderable circular connector
- Shielded twisted pair cabling
