 Above photo represents a QuickStart Kit. Kit cabling varies with MForce ordered. |
All-inclusive QuickStart Kits facilitate rapid design verification by bundling MForce 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 Communication Converter and Prototype Development Cable(s). Order QuickStart Kits simply by placing a “K” at the beginning of an MForce part number. Connecting an MForce 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 for details on these connectivity options. |

Communication 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.
To view specific connectivity options for each model MDrive, select from the drop-down listing above.
| Converter Part Number | Mating Connector Type |
| MD-CC303-001 (USB to SPI) | 12-Pin Tyco |
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.
To view specific connectivity options for each model MDrive, select from the drop-down listing above.
| Prototype Development Cable P/N | Mating Connector Type | Signal Type |
| PD12-1434-FL3 | 12-Pin Locking Wire Crimp | I/O, Power and Communications |
| PD04-MF34-FL3 | 4-Pin Locking Wire Crimp | Motor |
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 Kit
Used to build your own cables. Kits contain 5 mating connector shells with pins. Cable not supplied. Manufacturer crimp tooling recommended.

Drive Protection Module
The function of the DPM75 Drive Protection Module is to limit the surge current and voltage to a safe level when DC input power is switched on and off to a motor drive. This provides the added protection necessary for reliable motor drive operation when switching the DC power, instead of the recommended AC power to the DC power supply. The device is designed to protect the motor drive when operating under all load conditions. This device does not protect the motor drive from wiring the power incorrectly.
The unit is capable of being used with 48, 60, and 75 volt rated motor drives. An external jumper selection is available so the user can match the circuit to their particular application. The DPM75 is capable of a steady state operating current of 4 amps.
The DPM75 can be used for any frame size motor drive, when properly configured. It can also be used for more than one unit provided the current and voltage do not exceed the DPM75's ratings. The maximum DPM75 ratings are 75 volts and 4 amps.
