6.19.1 Functions under Position mode
Electronic gear function
If command frequency from controller is not enough which cause the motor to not
reach target rotational velocity, frequency can be increased using this function.

Pulses per revolution can be set using object dictionary 608F, 6091, 6092. However, Pr0.08 has
higher priority.

If 6092h-01(Feed constant) is not equal to 608Fh(Position encoder resolution), then:
Electronic gear ratio = Encoder resolution / 6092h-01
If 6092h-01(Feed constant) is equal to 608Fh(Position encoder resolution), then:
Electronic gear ratio = 6091-01 / 6092h-01
