It is compatible with the Automation 3200 motion platform utilizing the HyperWire® motion bus.

The current loop and servo-loop are digitally-closed to ensure the highest level of 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.

The XC2 includes safe torque off (STO), a data array consisting of over 4 million 32-bit elements, 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 XC2 accepts square-wave encoder feedback at rates of up to 40 million counts-per-second. Sine-wave encoders can be multiplied by up to 16,384 for high-resolution position feedback.

Each single-axis XC2 PWM digital drive has an optional I/O expansion board, greatly increasing the number of I/O points. This I/O board also includes a dedicated PSO output.
