Users Manual 1.00

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.

KP-1SM30

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
