9-1-3 Setting the output magnification
Set as follows to output with a unit other than the standard output unit.
(Example 1) When SV061 = 11 and SV063 = 2560
The position droop is output as a 0.1mm/V unit to D/A output channel 1.
(Example 2) When SV062 = 11 and SV064 = 128
The position droop is output as a 2mm/V unit to D/A output channel 2.

When "0" is set, the data is output with the standard output unit.
Set a value other than 0 to change the output unit.
The scale is set with a 1/256 unit. When 256 is set, the unit is the
same as the standard output unit.
Set a value other than 0 to change the output unit.
The scale is set with a 1/256 unit. When 256 is set, the unit is the
