Six-axis drive rack for brushed, brushless and stepper motors
Aerotech's XR3 six-axis drive rack with field-replaceable, front-mounted, 3U plug-in amplifiers supports both linear and PWM topologies. The XR3 can control any combination of brushless, DC brushed or stepper motors at up to 320V DC operating voltage and 30A peak current capability. Both the current loop and servo loop are digitally closed to ensure positioning accuracy and rate stability. This processing capability allows the XR3 to provide loop closure rates up to 20kHz and to handle both digital and analogue I/O processing, data collection, process control, and encoder multiplication tasks in real time.
Standard features include per-axis brake control logic, auxiliary encoder feedback, analogue I/O expansion, 16 opto-isolated inputs, 16 opto-isolated outputs, up to 12 high-speed differential outputs, three PSO (Position Synchronised Output) external sync inputs, three TTL or isolated PSO outputs, one opto-isolated data-acquisition input, and two STO (Safe Torque Off) sensor inputs. The XR3 supports open-loop control, standard square-wave encoder feedback, analogue input feedback control, and absolute encoder feedback.
Options for the XR3 include three different levels of integrated encoder multiplication including options that support dual-loop encoder feedback, drive-rack cooling, rack or slide-type mounting, and multi-axis PSO I/O for low-latency, position-based process control.
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.
