Measurement Of Adjustment Data; D/A Output Specifications; Setting The Output Data - Mitsubishi Electric MELDAS MDS-B-SVJ2 Series Specifications And Instruction Manual

5-1 Measurement of adjustment data

The MDS-B-SVJ2 servo amplifier has a function to D/A output the various control data. To adjust the
servo and set the servo parameters that match the machine, it is necessary to use the D/A output and
measure the internal status of the servo. Measure using a hi-coder, synchroscope, etc.
