DM330022-1

DM330022-1 is a DSPICDEM™ MCSM development board 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 H/W changes are necessary for 8, 6 or 4-wire stepper motors in either bipolar or unipolar configurations. S/W 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 DSCs. This board offers a mounting option to connect either 28-pin SOIC or generic 100-pin PIM. A dsPIC33CK64MP105 external op-amp MC PIM (MA330050-1) is included that features 4-ch, high-speed PWM with complementary mode O/P, programmable ADC trigger on PWM reload cycle, digital dead time control, internal shoot-through protection and hardware fault shutdown.

• Motor control interfaces: 2 full-bridge inverters, 2 phase current sense resistors, OCP
• Built-in power supplies: 15/3.3V power supply, max power available 11/2W
• Power supply connectors: 24V power input connector (J6) for the controller and power stage
• Auxiliary Power Tab Fast-On connectors (BP1 and BP2) for the power stage
• User interfaces: one push button (S1), Reset push button (RESET), 10K Ohm potentiometer (POT)
• LED indicators for PWM outputs arranged in a full-bridge format and LED indicator for over current
• Communication ports: UART communication via USB (J4)
• Programming connectors: ICSP™ connector for programming a dsPIC DSC device (J2)
• RJ11 connector for programming a dsPIC DSC device (J1)
• ICSP connector for programming the PIC18LF2450 USB-to-UART Bridge (J3)
