Working Principle
The motion processor receives position commands from the host or routine engine, reads encoder/feedback inputs, computes servo correction, and outputs analog or pulse commands to amplifiers. Sensor inputs are sampled, conditioned, and forwarded for process control and diagnostic logging.
Installation Requirements
- Verify PMAC firmware, axis count, and backplane type before insertion
- Confirm 48 V or 24 V supply according to the installed variant
- Align encoder, analog, and communication connectors using OEM pin maps
- Perform ESD handling and functional motion test before full wafer operation
Usage Notes
- Do not exchange PMAC firmware revisions without system compatibility check
- Validate axis homing, encoder polarity, and servo gains after replacement
- Inspect optical communication ports for contamination
- Keep spare configuration files and axis parameter backups
