Installation and Configuration

2.6.1. Analog Encoder Inputs (J201 and J202)

The Nmark GCL is equipped with two analog encoder input channels per Galvo connector that are used for
position feedback.
Each channel's gain, offset, and phase balance of the analog Sine and Cosine encoder input signals can be
adjusted by controller parameters. Encoder signals for each channel should be adjusted using the Feedback
Tuning tab of the Digital Scope utility, which will automatically adjust the encoder parameters for optimum
performance (refer to the A3200 Help file for more information).

1. Any single-ended encoder signal measured with respect to ground.

2.6.2. Galvo Motor Connection (J201 and J202)

The Nmark GCL is designed to control the AGV Galvo motors which operate as DC Brush motors over a
limited travel. The GCL must be factory-configured for the motor and cannot be used with any other motor
types.
