Part 4: Replacement of MR-J3W-_B with MR-J4W2-_B
No. Name and function
PC02 Electromagnetic brake sequence output
Used to set the delay time (Tb) between electronic brake
interlock (MBR-A/MBR-B) and the base drive circuit is
shut-off.
PC03 Encoder output pulse selection
Use to select the encoder output pulse direction and
encoder output pulse setting.

[AL. 37] while "Fully closed loop control mode (_ _ 1 _)"
is selected in [Pr. PA01].
