MITSUBISHI CNC
3-6 Diagnosis function
3-6-1 Monitor output function
<Servo drive unit>
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, oscilloscope, etc.
(1) D/A output specifications
When the output data is 0, the offset voltage is 2.5V. If there is an offset voltage, adjust the zero level
position in the measuring instrument side.
