Newport PM500 – Precision Motion Controller

The Newport PM500 is a precision motion controller engineered for nanometer-class positioning in research and industrial environments requiring high-accuracy multi-axis control. It executes complex motion sequences with real-time command capability through a distributed processor architecture—a central CPU paired with dedicated motion processors on individual axis cards. The modular chassis accepts up to 6 or 8 axis cards depending on configuration, enabling synchronized and non-synchronized point-to-point motion control across multiple axes.

– Technical Specifications

• Control Algorithm: Proprietary DSP algorithm stored in PROM
• Motion Profile: Proprietary design optimized for smallest incremental motions
• Motion Types: Synchronized and non-synchronized point-to-point positioning
• Axis Capacity: Up to 6 or 8 axes (configuration-dependent)
• Positioning Accuracy: Nanometer-class performance (factory-tuned, pre-matched sets); linear glass scales achieve better than 1 µm accuracy over full travel
• Resolution: Down to 0.050 µm (50 nm) with compatible actuators
• Metrology: Direct-output metrology with integrated linear glass scales eliminating drivetrain errors
• Encoder Input: High-performance analog inputs (1 Vpp Heidenhain standard) with signal interpolation for ultra-high resolution feedback
• Reliability: Greater than 20,000 hours MTBF

– Key Features

• Modular axis card architecture enabling scalable multi-axis configurations
• Real-time command execution via computer interfaces (RS-232, GPIB/IEEE-488)
• Multiple digital and analog I/O channels with trigger and supplemental encoder inputs
• Analog and digital servo control in PM500-C6 chassis configuration
• 500 W power supply for drive modules (typical)

– Compatibility & Integration

The PM500 controller drives Newport actuators, linear stages, and rotary stages. The PM500-C6 chassis is specifically designed and tuned for Newport PM500 Series ultra-precision motion devices. The PM500-K6 Remote Control Console provides manual motion operation and continuous position display for up to three selected axes within a six-axis maximum system.
