2.3.1.3. Analog Encoder [-MX1 Option]
NOTE:
Aerotech recommends that you use twisted pair wiring for all differential signals.
The interpolation factor is determined by the EncoderMultiplicationFactor parameter and is software
selectable.
Use the Feedback Tuning tab of Digital Scope to automatically adjust the value of the gain, offset, and
phase balance controller parameters to get the best performance. For more information, refer to the Help.
