General Scanning G100PD galvanometers

Pinout and wire colours for the G100PD galvanometers. This is NOT an official General Scanning document - for the latest info, contact General Scanning directly.
The G100PD galvos have not been manufactured for a number of years but are still plentiful in older systems and the surplus market.

G100PD wiring

There are two cables connected to the galvo, one is the galvo coil cable and the other is the position sensor cable.

Position sensor cable

Additional wires may be present on the G100PDT for the heater blanket and Thermistor (see note 3 below).

Drive coil cable

NOTES

1/ To wire drive coils in series, connect Black to Green and drive Red to Yellow. Series wiring is recommended for use in position sensing (closed loop) mode.

2/ To wire drive coils in parallel, connect Red to Green and Black to Yellow. Use parallel wiring only when driving the galvo in open-loop mode.

3/ Heater blankets are mounted only on the G100DT type galvos and are not commonly used in light show applications.
