Phase A
Phase B
Phase Z
When the dividing ratio is multiple of 4
Note: When Pn503 = 0 and the output resolution is set to Pn011, the dividing ratio is always a multiple of 4.
When en encoder with the incremental specifications is used, the first phase Z output after the
power supply is turned ON may not always be within the above pulse width.When you are using
the phase-Z signal, rotate the motor more than once after turning ON the power supply, and
confirm that phase-Z regeneration has been performed once before using the second and
subsequent phase Z outputs.
