11 Appx. 2: D/A Output Specifications for Drive Unit
474
IB-1501229-F
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.
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.
