Digital Galvo Driver

Digital Galvo Driver

The Digital Galvo Driver is a driver board for the full range of Scanner Optics photoelectric and grating galvanometer motors: one board drives two galvanometer motors at the same time. It supports a variety of digital communication protocols with state output and position feedback, and different debugging files can be configured per customer to meet the requirements of different applications. The grating-series board is matched to high-end grating galvanometer motors and reaches 23-bit position resolution, ensuring extremely low drift.

Key Features:

  • Load size 3-50mm aperture mirrors.
  • Support XY2-100 protocol, SPI protocol, ST2-100 protocol, differential digital signal input, and differential digital signal output.
  • Compact size, a variety of performance of driver are optional for different galvo motors and loads.
  • Based on high-speed FPGA control mode, support the information output for position, status and alarm.
  • A variety of debugging modes for different applications, such as Vector Tune, High Speed Tune, etc.
  • Suitable for Scanner Optics STGalvo series, UltraGalvo series and ExtraGalvo series galvanometers.
