[Example of calculation of electronic gear ratio]

To connect the ball screw (lead 10 mm) directly to the output shaft of the servomotor and set the

unit amount at 1/100, the number of encoder pulses (20 bits) is 1048576 rev.

Therefore numerator 0 and denominator of the electronic gear are 131072 and 125, respectively.

If the traveling amount of the mechanical system per

0.01 mm per pulse

servomotor revolution includes , you can approximate

to 355/113.

The number of output pulses is irrelevant to command

pulse correction.

A / B phase pulse in B-phase advance are output

according to the reference value of PA1_08 (number

10 mm per 1000 pulses

(one full motor revolution)

of output pulses per revolution) during forward rotation of the motor shaft.
