Galil Motion Control (Rocklin, CA) offers the DMC-300xx Pocket Motion Controller Series, a single-axis Ethernet motion controller that combines a motion controller and an 800W sine drive in a 3.9 × 5.0 × 1.5" package. It is also available as a controller-only model that can be connected to a stepper or servo motor amplifier of any power range. The controller uses a 32-bit RISC processor and features a 15-MHz encoder frequency, 125- microsecond servo loop update time, and 3-MHz stepper pulse output. The controller drives brushless servomotors at 20-80 VDC, up to 10 Amps continuous, and 15 Amps peak. The digital transductance amplifier is a sinusoidally commutated brushless motor amplifier that minimizes torque ripple. Modes of motion include point-to-point positioning, position tracking, jogging, contouring, electronic gearing, ECAM, and PVT. It provides optically isolated inputs and outputs.
