No./ Setting
symbol/name digit
PC19 _ _ _ x Encoder output pulse phase selection
*ENRS Select an encoder pulse direction.
Encoder 0: Increasing A-phase 90° in CCW or positive direction
output pulse
1: Increasing A-phase 90° in CW or negative direction
selection
_ _ x _ Encoder output pulse setting selection
0: Output pulse setting
1: Division ratio setting
2: The same output pulse setting as command pulse
3: A-phase/B-phase pulse electronic gear setting
4: A/B-phase pulse through output setting
When you select "1", the settings of [Pr. PA16 Encoder output pulses 2] will be
disabled.
When you select "2", the settings of [Pr. PA15 Encoder output pulses] and [Pr. PA16
Encoder output pulses 2] will be disabled. Additionally, it will be the servo motor side
pulse unit for the indexer method. When you select the setting, do not change the
settings in [Pr. PA06] and [Pr. PA07] after the power-on.
Setting "4" will be enabled only when A/B/Z-phase differential output linear encoder is
used. And "Encoder output pulse phase selection (_ _ _ x)" will be disabled. When
another encoder is connected, [AL. 37 Parameter error] will occur. Setting "Standard
control mode (_ _ 0 _)" in [Pr. PA01] will trigger [AL. 37 Parameter error].
_ x _ _ Selection of the encoders for encoder output pulse
Select an encoder used the encoder output pulses which the servo amplifier outputs.
0: Servo motor encoder
1: Load-side encoder
This is only for the fully closed loop system.
If "1" is set other than in the fully closed loop system, [AL. 37 Parameter error] will
occur.
x _ _ _ For manufacturer setting
PC20 Specify a station No. of the servo amplifier for RS-422 and USB communication.
*SNO Always set one station to one axis of the servo amplifier. Setting one station number to
two or more stations will disable a normal communication.
