C2000™ Systems Applications Collateral
v2.0
2
The software available with the kit is pre-optimized for the included motors. The software is open source, and
can be modified to tune and run a different motor. The following motors are available with the kit:
Bi-polar Stepper Motor
(4.2A/phase (parallel) , 8-wire, 1.8°/step)
Brushed DC Motor
(6-24V, 0.92A)
Hardware Overview
Below is a list of all the major functional blocks present on the board and a short description of its function, Fig
2, shows the location of these blocks on the motor control board and a few key connector locations.
ISO controlCARD socket: controlCARD slot; controlCARD has built-in isolated XDS100 emulator.
+12V Control Power Entry: Connectors to optionally provide an external 12V supply for logic and gate drive
power. The 12V supply can also be regulated on board from the DC bus depending on the setting of JP1.
DC Bus Power Entry: Connect the +24V AC/DC supply provided with the kit.
DRV8412: DRV8412 Dual Full Bridge PWM Motor Driver as well as external passive components.
Current Sense: Low-side shunt current sensing on each half-bridge.
Reset Switch: Individual reset for each H-bridge, forced manually or through a GPIO from the MCU.
Mode Jumpers: Enable/disable c-by-c current limit, latched over-current and parallel or dual full-bridge mode.
Quadrature Encoder: Connections for an optional shaft encoder to interface to the MCU’s QEP peripheral.
