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 to adjust the value of the gain, offset, and phase balance controller parameters to get the best performance. For more information, refer to Automation1 Help.
