2.1.2 Setting the Volts/Degree Scaling Factor
The servo driver cards have a jumper which is used to set the Volts per Degree
scaling factor. The cards are shipped with the scaling set to 0.5 V/°, where the max
mechanical scan angle is nominally ±20° for the full ±10 V input.
To set the scaling factor to 0.8 V/° or 1.0 V/°, proceed as follows:
1) Identify JP7 as shown in Fig. 3.13.
2) Set the jumper position for the corresponding scaling factor as shown below.
