5-1 D/A output specifications for spindle drive unit
The drive unit has a function to D/A output each control data. The spindle adjustment data required to set the
spindle parameters matching the machine can be D/A output. The data can be measured with a high-speed
waveform recorder or oscilloscope, etc.
5-1-1 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.
