When using an encoder of A/B/Z-phase differential output method,
set "0".
Incorrect setting will result in [AL. 16 Encoder initial communication
error 1]. Or [AL. 20 Encoder initial communication error 1] will
occur. Setting "1" will trigger [AL. 37] while "Fully closed loop
control mode (_ _ 1 _)" is selected in [Pr. PA01] (except MR-J4-
_B_-RJ).

PC05 **COP2 Function selection C-2
Set the motor-less operation and [AL. 9B Error excessive warning]. The motor-less operation
is not available in the linear servo motor control mode, fully closed loop control, and DD motor
control mode.
Refer to the

PC08 OSL Overspeed alarm detection level
This is used to set an overspeed alarm detection level.
When you set a value more than "servo motor maximum speed × 120%" or "linear servo motor
maximum speed × 120%", the set value will be clamped.
When you set "0", the value of "(linear) servo motor maximum speed × 120%" will be set.
