dsPICDEM MCSM Development Board

Part Number: DM330022-1

Summary:

The Microchip dsPICDEM™ MCSM Development Board is targeted to control both unipolar and bipolar stepper motors in open-loop or closed-loop (current control) mode. The hardware is designed in such a way that no hardware changes are necessary for 8-, 6- or 4-wire stepper motors in either bipolar or unipolar configurations. Software to run motors in open-loop or closed-loop with full or

Summary

The Microchip dsPICDEM™ MCSM Development Board is targeted to control both unipolar and bipolar stepper motors in open-loop or closed-loop (current control) mode. The hardware is designed in such a way that no hardware changes are necessary for 8-, 6- or 4-wire stepper motors in either bipolar or unipolar configurations. Software to run motors in open-loop or closed-loop with full or variable micro-stepping is provided. A GUI for controlling step commands, motor parameter input, and operation modes is included. This flexible and cost-effective board can be configured in different ways for use with Microchip’s specialized dsPIC33 Motor Control Digital Signal Controllers (DSCs). The dsPICDEM MCSM Development Board offers a mounting option to connect either a 28-pin SOIC device or a generic 100-pin Plug-In Module (PIM). A dsPIC33CK64MP105 External Op Amp MC PIM (MA330050-1) is included.

The dsPICDEM MCSM Development Board supports terminal voltages up to 80V and currents up to 3A. The dsPIC33C device uses the MOSFET driver to drive the two full-bridge inverters that power the motor windings. The board includes various circuits to perform the following functions:

  • Drive two motor windings with the two on-board full-bridge inverters
  • Measure feedback and other analog signals (i.e., current, DC voltage, Potentiometer and Fault signals)
  • Communicate with a host computer or an external device via USB

The dsPIC33CK64MP105 devices feature an 4-channel, high-speed PWM with Complementary mode output, a programmable ADC trigger on the PWM reload cycle, digital dead time control, internal shoot-through protection and hardware fault shutdown. These features make the dsPIC DSC an ideal solution for high-performance stepper motor control applications where control of the full-bridge inverter is required.
