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 hi-coder, synchroscope, etc.

Lead out with the SH21 cable from
the CN9 connector and connect.
Input the No. of the data to be output to each D/A output channel.
(Note) When using the 2-axis drive unit (MDS-R-V2), set "0" for the data No. of the
other axis in the same drive unit which is not to be D/A output.
