Single-axis PWM drive for brushless/brush dc, voice coil, and stepper motors

April 4, 2019 By Miles Budimir Leave a Comment

The new XC4e PWM digital drive from Aerotech is a high-performance single-axis motor drive to control brushless dc, brush dc, voice coil, or stepper motors at up to 340 Vdc operating voltage and 30 A peak current capability. All versions are compatible with the Automation 3200 motion platform utilizing the HyperWire motion bus.drive

The digitally closed current loop and servo loop ensure the highest level of positioning accuracy and rate stability. This allows loop closure rates up to 20 kHz 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 16 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 XC4e accepts square-wave encoder feedback at rates of up to 40 million counts-per-second. Sine-wave encoders can be multiplied by up to 65,536 with the optional encoder multiplier feature. Dual-multiplied encoder feedback is also supported.

Each single-axis XC4e PWM digital drive can be ordered with the MX2 high-performance single encoder multiplier or the MX3 high-performance dual-loop encoder multiplier, enabling higher levels of position and velocity control. Also available are a wide variety of extensions to the base PSO functionality. Track up to three encoders in real time with three-axis PSO or extend PSO’s functionality to kinematic arrangements through the use of Aerotech’s Part-Speed PSO feature.

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