7-6 Extended Parameters
• Encoder pulses are divided based on the following formula if Encoder Dividing Denominator is not 0.
Therefore, if the host system generated a pulse count in the quadruple process, the resolution of
pulse output per rotation can be calculated using the following formula.
Resolution of pulse output per rotation = x Encoder resolution
• The resolution of pulse output per rotation is not more than the encoder resolution. (With the above
settings, the resolution of pulse output per rotation is equal to the encoder resolution.)
• For the phase-Z signal, one pulse will be output per motor rotation.
• The phase-Z signal will be output in sync with the phase-A signal when the resolution of pulse output
per rotation calculated using the above formula is a multiple of 4. In other cases, however, the phase-
Z signal will not be synchronized with the phase-A signal because it is output at the encoder
resolution and its width is narrower than the phase-A signal.
