Chapter 3 Installation & Initial Set Up
Servo Driver Board Heatsink
The servo driver board is supplied complete with a large heatsink, suitable for all applications,
even those involving more vigorous usage and rapidly changing drive waveforms.
1) Secure the heatsink bracket to the heat sink using two M3 x 8 screws and two
plain M3 washers (arrowed in the photo below).

Motor/Mirror Mount Heat Sink
For most applications, the mounting bracket will provide adequate heat sinking,
however for more vigorous applications, it may be necessary to fit some heatsinking
in addition to the galvo motor mount. Thorlabs supply a combined post adapter and
heatsink (GHS003) suitable for both single and dual axis applications.
If using a third party heatsink, please see Appendix B for details on how to calculate
the power dissipation in the motor.
1)
Secure the heatsink to the motor/mirror mount using the two M3 x 5 screws supplied
.

Caution
Due to the large torque to weight ratio, thermal managment is crucial to the
successful operation of galvo motors. Consequently the galvo motors must be
kept cool (<50 °C).
