Galvo Motor Connectors

The GL4 is configured for AGV galvo motors at the factory. You cannot use the GL4 with other types of motors. AGV galvo motors operate as DC Brush motors over a limited travel.

Each galvo motor connector is a 25-pin, D-style connector that has two analog encoder inputs, 5 V encoder power, and galvo motor connections.
