Chapter 3 Installation & Initial Set Up
6) Note the serial numbers then connect the galvo motors to their associated driver
boards
Fig. 3.10 Galvo Assembly Motor Connector Pin Identification
7) Connect a command input (e.g. function generator) to J7 of each driver board as
shown in Fig. 3.11. J7 accepts Molex pins Pt No 56134-9100.
Note
The scanner accepts a differential analog command input. If the scaling is 0.8 Volt
per degree mechanical movement (see Section 3.3.5.), -10 V to +10 V gives -12.5
to +12.5 degrees mechanical movement. The driver will attempt to set the mirror
position to the command input value.
Pin 3 (DRV_OK) is an open collector output that is low when the board is operating
normally and floating if a fault occurs. To use Pin 3 as a fault indicator, connect a
pull-up resistor to give a high signal when the fault occurs. DRV_OK limits are 30 mA
30 V.
Do not connect a relay to this output.
