- On some models, such as SGMAH and SGMPH, the absolute encoder has better resolution than incremental (16-bit vs. 13-bit), which can lead to better performance and tuning.
- If an incremental encoder motor is unavailable, then an absolute encoder motor could be substituted without operational change.
- Absolute encoder needs a battery when operating, but when it's used as incremental, the battery is not needed.
To set the SGDH servopack to read an absolute encoder as incremental encoder, set Pn002.2=1
