The XR3 is a high-performance, six-axis drive rack with field replaceable front-mounted amplifiers. All versions are 3U in size, rack-mountable, and compatible with the Automation 3200 motion platform.

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.

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.

Aerotech offers both standard and custom integration services to help you get your system fully operational as quickly as possible. The following standard integration options are available for this system. Please consult Aerotech if you are unsure what level of integration is required, or if you desire custom integration support with your system.

-TAS Integration - Test as system
Testing, integration, and documentation of a group of components as a complete system that will be used together (ex: drive, controller, and stage). This includes parameter file generation, system tuning, and documentation of the system configuration.
-TAC Integration - Test as components
Testing and integration of individual items as discrete components that ship together. This is typically used for spare parts, replacement parts, or items that will not be used together. These components may or may not be part of a larger system.
