5-1 D/A output specifications for spindle drive unit
The MDS-C1-SP/SPH/SPX/SPHX/SPM spindle 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 hi-corder or oscilloscope, etc.
