setting
Set a station No. of the servo amplifier for RS-422 and USB communication.
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.

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).

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.

_ 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.
