A USB-CAN-Based Distributed Dual-Axis Motion Controller
During
the development of automation equipment, the rapid prototyping
of multiaxis designs is often required. You can use centralized
controls with PC motion control cards, external amplifiers,
and a tangle of wires, or utilize an existing high-cost distributed
motion control system with RS-485, Ethernet, or one of the field
buses (DeviceNet, CANopen, Profibus, etc.). With a highly integrated
microcontroller—the PIC18F258—and power devices like the Allegro
A3977/A3959, a small and inexpensive distributed motion control
system was developed.
