Aerotech’s XC4 PWM digital drive is a single-axis motor drive designed for brushless DC, brush DC, voice coil, and stepper motors at up to 340VDC operating voltage and 30A peak current. All versions are compatible with the Automation 3200 motion platform utilizing the HyperWire motion bus.

The digitally closed current loop and servo-loop ensure positioning accuracy and rate stability. This allows loop closure rates up to 20kHz as well as digital and analog I/O processing, data collection, process control, and encoder multiplication tasks in real time.

Standard features include Safe Torque Off (STO), a data array consisting of over 4 million 32-bit elements, digital and analog I/O, one-axis position synchronized output (PSO), dedicated home and end-of-travel limit inputs, and an enhanced current sense device. Encoder support includes square-wave, sine-wave, and absolute encoders.

The standard XC4 accepts square-wave encoder feedback at rates up to 40 million counts-per-second. Sine-wave encoders can be multiplied by up to 16,384, producing high-resolution position feedback with the optional encoder multiplier feature.

Each single-axis XC4 PWM digital drive has an optional I/O expansion board, greatly increasing the number of I/O points. This I/O board includes a dedicated PSO output and a PSO synchronization input, often used to synchronize process control with an external mode-locked frequency input.
