_ _ x _ Encoder output pulse setting selection
For linear servo motors, selecting "0" will output as division ratio setting because the output pulse setting is
not available.
0: Output pulse setting
1: Division ratio setting
The setting of [Pr. PA16 Encoder output pulses 2] will be disabled.
3: A-phase/B-phase pulse electronic gear setting
4: A/B-phase pulse through output setting
The setting value is available with servo amplifiers with software version A1 or later.
 Page 635 Encoder output pulse setting method
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].
0h
_ x _ _ Selection of the encoders for encoder output pulse
Select an encoder used for the encoder output pulses which the servo amplifier outputs.
This is only for the fully closed loop system.
If "1" is set in other systems than the fully closed loop system, [AL. 37 Parameter error] will occur.
The setting of this digit is used by servo amplifier with software version A1 or later.
0: Servo motor encoder
1: Load-side encoder
When "_ 1 0 _" is set to this parameter, [AL. 37 Parameter error] will occur. 0h

x _ _ _ Encoder cable communication method selection
Select an encoder cable communication method.
0: Two-wire type
1: Four-wire type
When using an encoder of A/B/Z-phase differential output method, set "0".
If the setting is incorrect, [AL. 16 Encoder initial communication error 1] or [AL. 20 Encoder normal
communication error 1] occurs. 0h
PC05
**COP2
Function selection
C-2 _ _ _ x Motor-less operation selection
Set the motor-less operation. The motor-less operation cannot be used in the fully closed loop control mode,
linear servo motor control mode, or DD motor control mode.
