XPS-D Controller Start-Up Manual
2.0 System Overview
2.1 Specifications
Number of Axes
• 1 to 8 axes of stepper, DC brush, DC brushless or linear motors using internal drives:
XPS-D2: 2-axis; XPS-D4: 4-axis; XPS-D6: 6-axis; XPS-D8: 8-axis.
NOTE: Lower versions are upgradable up to 8-axis. Contact Newport for additional
information.
• Other motion devices using external third-party drives
Communication Interfaces
• Internet protocol TCP/IP
• EtherCAT Communication (Slave), as an option
• One Ethernet 10/100/1000 Base-
T (RJ45 connector) with fixed IP address and DHCP
server for local communication
• One Ethernet 10/100/1000 Base-
T (RJ45 connector) for networking, dynamic addressing
with DHCP and DNS
• Typically 0.3 ms from sending a tell position command to receiving the answer
Firmware Features
• Powerful and intuitive, object-oriented command language
• Native user-defined units (no need to program in encoder counts)
• Real-time execution of custom tasks using TCL scripts
• Multi-user capability
• Concept of sockets for parallel processes
•
Distance spaced trigger output pulses, max. 1.6 MHz rate (5 MHz for less than 4096
pulses), programmable filter
• Array-
based compensated position trigger output pulses, max 1.6 MHz (5 MHz for less than
4096 pulses)
• Time spaced trigger output pulses, 0.05 Hz to 20 MHz, 5 ns accuracy
• Trigger output on trajectories (depending on servo rate)
• Data gathering at servo rate, up to 1,000,000 data entries (depending on servo rate)
• User-defined “actions at events” monitored by the controller autonomously at the servo rate
• User-
definable system referencing with hardware position latch of reference signal
transition and “set current position to value” capability
• Axis position or speed controlled by analog GPIO input
• Axis position, speed or acceleration copied to analog GPIO output
• Trajectory precheck function replying with travel requirement and max. possible speed
• Auto-configuration, auto-tuning and auto-scaling
Motion
• Jogging mode including on-the-fly changes of speed and acceleration
• Synchronized point-to-point
• Spindle motion (continuous motion with periodic position reset)
• Line-arc mode (linear and circular interpolation incl. continuous path contouring)
• Splines (Catmull-Rom type)
• PVT (complex trajectory based on position, velocity and time coordinates)
• Analog tracking (using analog input as position or velocity command)
• Master-slave including single master-multiple slaves and custom gear ratio
Compensation
• Linear error, Backlash, positioner error mapping
• XY and XYZ error mapping
• All corrections are taken into account on the servo loop
• Adjustable up to 20 kHz
