Note:
The analog monitor output is from the D/A converter of the controller.
Since the output range of the D/A converter is from –3 to +3 V, output is looped by magnification
setting if it exceeds this range.
The relationship between encoder pulse and angle depends on the galvano motor.

360° = 83328 pulses × 2048 divisions = 170655744 pulses
0.01° = 170655744 pulses / 360° 0.01 = 4740 pulses
At the monitor output position (0.091 V/pulse), the analog monitor output changes:
0.01° = 4740 × 0.091 = 431 mV
