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.

SV064  DA2MPY  D/A output channel 2 output 
magnification 
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 the speed loop gain (SV005: VGN1) to approx. 50 to 100, disconnect the 
resonance filter, and measure the waveform while the axis is stopped. 
The phase current is output to the CN9 
pin. Connect a high-speed waveform 
recorder, etc. between the GND (pin 1) 
and the phase current to be measured, 
and observe the state.
