CSDP Plus Servo Drive User Manual

In the case of moving a belt 100 µm per one pulse, whose speed
reduction ratio is 5 and the number of pulses of the encoder is 2048,
the numerator of the electronic gear is 10240, and the denominator is
calculated by the following method.
Denominator = Movement distance of the load per revolution/Distance to
move by one pulse
If the diameter of the pulley on the load side is 50 mm and the distance
to move by one pulse of the controller is 100 µm, the denominator is
1570.
50 π mm/100 µm = 1570
In this case, if 1570 pulses are approved by the controller, the pulley at
the end devices makes one revolution and the straight moving
distance of the end load is 100 µm.
In case of rotating a turntable 0.1° per pulse, whose speed reduction
ratio is 3 and the number of pulses of the encoder is 2048, the
numerator of the electronic gear is 6144 and the denominator can be
calculated by the following method.
Denominator = Movement angle of the load per revolution/Angle to move
with one pulse
