Page 4: Chapter 1 Introduction
Introduction Intended Use This manual covers the installation and use of the Thorlabs Class 1 Servo Amplifier Board that accompanies the QG4 and QG5 Galvanometer Systems. This servo amplifier board is intended to control the paired motor with a wide range of loads under a variety of command input conditions. The servo amplifier comes affixed to a mounting bracket for flexible integration into larger systems. - Page 5 Thorlabs.com. When two single-axis galvo systems are to be used as a pair, it becomes necessary to match-tune these as a set. For additional information on purchasing XY Galvo Pairs, please contact Thorlabs Technical Sales Team. Page 2...

<100 mV ripple, <0.5% DC to 30 MHz noise should be used. Switching-style supplies typically exceed acceptable noise levels and are not recommended. Suitable power supply options can be found on Thorlabs.com. 1) Adjust the power supply output to within the proper range. -
Page 15: Ground Connections
Class 1 Servo Amplifier for QG4/QG5 Galvos Chapter 5: Operation 4.3.4 Ground Connections Proper grounding is required for optimal system performance. Due to the susceptibility of galvo systems to electronic noise, the system should have a dedicated power supply to avoid interference entering through the grounding. -

Section 2.4.3. The mating connector is a Molex 51090-0800 connector with (8) Molex 50212-8000 or 50212-8100 pins. The pins should be used with AWG 24-30 wire. A pre-made cable assembly with this connector and fly leads is available for purchase from Thorlabs. Position Output The position output signal (J12, Pin 1) provides a scaled instantaneous position output from the galvanometer that is buffered through an amplifier. -

Class 1 Servo Amplifier for QG4/QG5 Galvos Chapter 6: Troubleshooting and Repair Current Monitor The current signal (J12, Pin 7) is the current that is being sent to the galvanometer coil. This signal is represented as 1V/Amp of current in the coil. High frequencies and large steps result in greater current draw, which results in increased temperature in the system and may require additional thermal management. -
