The XC2 PWM digital drive is a small form-factor, high-performance single-axis motor drive designed for motion control applications. All versions are compatible with the Automation 3200 motion platform utilizing the HyperWire® motion bus.

The XC2 can control brushless DC, brush DC, voice coil, or stepper motor types at up to 100 VDC operating voltage and 10 A peak current capability.

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

Standard features for the XC2 include 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 standard 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, producing
high-resolution position feedback, with the optional encoder multiplier feature.

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

  1. For stepper motors only, one-half of bus voltage is applied across the motor (e.g., 100 VDC supply results in 50 VDC across stepper motor)
  2. Output voltage dependent upon input voltage.
  3. Peak value of the sine wave; rms current for AC motors is 0.707 * Apk.
  4. Multiplied encoder cannot be echoed out.
  5. Dependent on total output power: efficiency increases with increasing output power.
