The Resolute™ true-absolute encoder is a high-speed fine-resolution position measurement system. Position is acquired immediately on start-up, without requiring any motion, offering smooth velocity control and dependable positional stability.
Combining advanced optics with innovative position determination algorithms, the Resolute encoder measures absolute position with fine resolutions down to 1 nm and high speeds up to 100 m/s. This delivers exceptional metrology performance such as low Sub-Divisional Error (SDE) of ±40 nm and ultra-low noise (jitter) of less than 10 nm RMS, suitable for the most demanding motion control challenges.
Resolute encoders are available with linear and rotary scales with a variety of serial interfaces. Application-specific variants including Resolute UHV (Ultra-High Vacuum), Resolute ETR (Extended Temperature Range) and Resolute FS (Functional Safety) are compatible with the optional Advanced Diagnostic Tool ADTa-100 and ADT View software, which acquire comprehensive real-time encoder data allowing optimisation and in-field fault finding.
True-absolute position measurement
The Resolute encoder series provides absolute position measurement from single-track linear and rotary scales. Position is acquired immediately on start-up without requiring any motion.
High speed and fine resolution
Resolute encoders combine advanced optics with innovative position determination algorithms to measure absolute position with fine resolutions down to 1 nm and high speeds up to 100 m/s (36 000 rpm).
Excellent metrology performance
Resolute encoder systems provide absolute position measurement with low Sub-Divisional Error (SDE) of ±40 nm and ultra-low noise (jitter) of less than 10 nm RMS, resulting in smooth velocity control performance and dependable positional stability.
Optional Advanced Diagnostic Tool ADTa-100
Resolute encoder readheads (marked with the ADT symbol) are compatible with the Advanced Diagnostic Tool ADTa-100 and ADT View software. They provide comprehensive real-time encoder data feedback to aid more challenging installations and diagnostics. The intuitive software interface can be used for:
- Remote calibration
- Signal optimisation over the entire axis length
- Digital readout of encoder position (relative to the scale)
- Exporting and saving data
- Setting zero
