Microchip Technology dsPICDEM™ MCSM Development Board (DM330022-1)
Microchip Technology dsPICDEM™ MCSM Development Board (DM330022-1) is targeted to control both unipolar and bipolar stepper motors in open-loop or closed-loop (current control) mode. The dsPICDEM MCSM Board is designed so 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 (Graphic User Interface) is included to control step commands, motor parameter input, and operation modes.
The dsPICDEM MCSM Development 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 onboard 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 a 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.
