x _ _ _ Encoder cable communication method selection
Select the 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. Setting "1" will trigger [AL. 37] while
"Fully closed loop control mode (_ _ 1 _)" is selected in [Pr. PA01] (except MR-J4-
_A_-RJ).
For MR-J4-03A6 servo amplifiers, this digit cannot be used when a setting value
other than the initial value is set. Also, it does not comply with encoders of A/B/Z-
phase differential output method.

*COP2
Function
selection C-2 _ _ _ x Servo-lock selection at speed control stop
Select the servo-lock selection at speed control stop.
In the speed control mode, the servo motor shaft can be locked to prevent the shaft
from being moved by an external force.
0: Enabled (servo-lock)
The operation to maintain the stop position is performed.
1: Disabled (no servo-lock)
The stop position is not maintained.
The control to make the speed 0 r/min or 0 mm/s is performed.
0h
_ _ x _ For manufacturer setting 0h
_ x _ _ VC/VLA voltage averaging selection
Select the VC/VLA voltage average.
Set the filtering time when VC (Analog speed command) or VLA (Analog speed limit)
is imported.
Set 0 to vary the speed to voltage fluctuation in real time. Increase the set value to
vary the speed slower to voltage fluctuation.
