D/A output specifications for servo drive unit

The MDS-C1-V1/V2 servo drive unit has a function to D/A output the various control data.
The servo adjustment data required for setting the servo parameters to match the machine can be D/A
output. Measure using a hi-coder, oscilloscope, etc.

With the MDS-C1-V1/V2 Series, there is a 2.5V offset voltage (2.5V when data is 0), so the zero level
position must be adjusted on the hi-corder side.
4. Servo Adjustment
"Chapter 4 Servo adjustment" explains the methods when controlling with the
high-gain specifications.

The D/A output for the 2-axis unit
(MDS-C1-V2) is also 2ch. When using
the 2-axis unit, set -1 for the output data
(SV061, 62) of the axis that is not to be
measured.
