Encoder output pulses
Set the encoder output from the servo amplifier by using the number of output pulses
per revolution, dividing ratio, or electronic gear ratio. (after multiplication by 4)
The setting value varies depending on [Pr. PC03.1 Encoder output pulse setting
selection].
Initial value: 4000 [pulse/rev]
PA16
*ENR2
Encoder output pulses 2
Set a denominator for the electronic gear when selecting "3" (A-phase/B-phase pulse
electronic gear setting) in [Pr. PC03.1 Encoder output pulse setting selection]. This is
not used for other settings.
Initial value: 1
PC03.0
*ENRS
Encoder output pulse - Phase
selection
Set the phase for the A-pulse and the B-pulse.
0: Increasing A-phase 90° in CCW or positive direction (initial value)
1: Increasing A-phase 90° in CW or negative direction
PC03.1
*ENRS
Encoder output pulse setting
selection
Select the method for setting the number of output pulses.
0: Output pulse setting (initial value)
1: Dividing ratio setting
3: A-phase/B-phase pulse electronic gear setting
4: A/B-phase pulse through output setting
*ENRS
Encoder selection for encoder
output pulse
Select a servo motor encoder or load-side encoder for the encoder to output pulses.
0: Servo motor-side encoder (initial value)
1: Load-side encoder
