*ENR
Encoder
output pulses Set the encoder output pulses from the servo amplifier by using the number of
output pulses per revolution, dividing ratio, or electronic gear ratio. (after
multiplication by 4)
To set a numerator of the electronic gear, select "A-phase/B-phase pulse electronic
gear setting (_ _ 3 _)" of "Encoder output pulse setting selection" in [Pr. PC19].
The maximum output frequency is 4.6 Mpulses/s. Set the parameter within this
range.
