Torque/Speed Curve

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 differential magnetic encoder. The internal magnetic encoder offers several 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.

An optional encoder cable is available (order separately):
     Internal Encoder Cable (10.0'/3.0m) … p/n: PD10-3400-FL3

A mating connector kit with shells and pins is available to build your own encoder cable:
     10-pin Wire Crimp … p/n: CK-02

External encoder
Gives the user the option of using an optical encoder. Available in single-end and differential configurations with the following line counts: 100, 200, 250, 256, 400, 500, 512, 1000, 1024.

Optional external encoder cables are available (order separately):

Single-end Cable (12.0"/30.5cm)	p/n: ES-CABLE-2
Differential Locking Cable (6.0'/1.8m)	p/n: ED-CABLE-6

 

Combining leading all-in-one integrated step motor+driver technology with linear motion to deliver long life, high accuracy and unsurpassed repeatability, all in a package that is extremely compact and affordable.

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.

Converter Part Number	Mating Connector Type
MD-CC305-001 (USB to SPI)	12-Pin JST

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

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.

Prototype Development Cable P/N	Mating Connector Type	Signal Type
PD12B-1434-FL3	12-Pin Locking Wire Crimp	I/O, Power and Communications

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) or solder station (19-Pin M23)
• Shielded twisted pair cabling

 

Mating Connector Kits

Mating Connector Kits are used to build your own cables. Kits contain 5 mating connector shells with pins. Cable not supplied. Manufacturer crimp tooling recommended.
