The XC2 PWM digital drive is a small form-factor, high-performance, single-axis motor drive designed for motion control applications. It is compatible with the Automation 3200 motion platform using the HyperWire motion bus. It can control brushless dc, brush dc, voice coil and stepper motors at up to 100-Vdc operating voltage and 10-A peak current capability. The current loop and servo-loop are digitally closed to ensure the positioning accuracy and rate stability. This allows loop closure rates of up to 20 kHz while also permitting real-time digital and analog I/O processing, data collection, process control and encoder multiplication.
