11.1 D/A Output Specifications

Drive unit has a function to D/A output the various control data. The servo and spindle adjustment data required for
setting the servo and spindle parameters to match the machine can be D/A output. Measure using a high-speed
waveform recorder, oscilloscope, etc.
Note that the output pins differ between MDS-EJ/EJH-V1, MDS-EJ-SP and MDS-EJ-V2/SP2.

The D/A output for the 2-axis or 3-axis unit is also 2ch. When using the 2-axis or 3-axis unit,
always set -1 for the output data (SV061, SV062 / SP125,SP126) of the axis that is not to
be measured.
