2.5.1. Analog Encoder Inputs
The GL4 has two analog encoder input channels for each galvo connector. The GL4 uses these input
channels for position feedback.
Use Encoder Tuning [A3200: Feedback Tuning] to adjust the value of the gain, offset, and phase balance
controller parameters to get the best performance. For more information, refer to the Help file.
