9-1 Servo adjustment data output function (D/A output)

The MDS-R-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 high-speed waveform recorder, synchroscope, etc.
