The dividing output phase form is the same as the standard setting(Pn001.0=0) even if inreverse rotation
mode(Pn001.0=1).

If the servomotor is not equipped with an absolute encoder, the servomotor needs two full rotations before using the servo
drive's Phase-C pulse output as the zero point reference.
Dividing: Dividing means that the divider converts data into the pulse density(Pn200) based on the pulse data of the
encoder installed on the servomotor, and outputs it. The setting unit isnumber of pulses/revolution.
