Featuring high-performance control electronics, the XR3 is Aerotech’s highest performing multi-axis controller. Both the current loop and servo-loop are closed digitally to assure the highest level of positioning accuracy and rate stability. This processing capability allows the XR3 to provide loop closure rates up to 20 kHz and to handle both digital and analog I/O processing, data collection, process control, and encoder multiplication tasks in real time.
See how Automation1 Servo Drives Improve In-Position Stability.
Standard features for the XR3 include per axis brake control logic, auxiliary encoder feedback, and analog I/O expansion. Also standard are 16 opto-isolated inputs, 16 opto-isolated outputs, up to 12 high-speed differential outputs, 3 PSO external sync inputs, 3 TTL or isolated PSO outputs, 1 opto-isolated data-acquisition input, and 2 STO sense inputs.
The XR3 supports open-loop control, standard square-wave encoder feedback, analog input feedback control, and absolute encoder feedback.
Standard options for the XR3 include three different levels of integrated encoder multiplication including options that support dual-loop encoder feedback, drive-rack cooling options, rack or slide-type mounting options, and multi-axis Position Synchronized Output (PSO) I/O for low-latency, position-based process control.
Also available are a wide variety of extensions of 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.
The XR3 uses plug-in amplifiers supporting both linear and PWM topologies to control brushless, DC brush, or stepper motor types at up to 320 VDC operating voltage and 30 A peak current capability. The XR3 contains two configurable power supply sections to support a variety of motors with different operating voltages. When only one motor voltage is required, the power supply sections are joined together for even higher power capability. The XR3 supports up to three axes of Position Synchronized Output (PSO) for precise synchronization of external devices, over-voltage shunt controller, and external fans for high-power operation.

2. AC voltage and bus supply/load may result in significantly lower maximum peak currents.
3. This specification depends on the motor supply voltage, the motor speed, and motor resistance. Contact an Aerotech sales engineer for more information.
4. Peak and continuous output current is load dependent. The controller will limit output current based on velocity and motor resistance. The first number is for a stationary AC or DC motor. The second number is for an AC motor that is in motion. This specification assumes that an AC or DC motor type with a 0 Ω winding resistance is used. The specification will de-rate when the ambient temperature exceeds 25°C. Contact an Aerotech sales engineer for stepper motor operation.
5. Selectable through parameters.
