[How to check and adjust the position of encoder phase Z]
Follow the procedures below to check if encoder phase Z is at an appropriate position. This is
required only for RP3NA, RP3N (slip screw) actuators with a lead of 1 mm.
[Procedure 1] Checking the position of encoder phase Z
[1] Turn the shaft clockwise from the rear until the rod contacts the rear end.
Recommended screwdriver size:
Nominal size 5.5 to 6.0 (width at tip)
[2] In rear view, confirm that the cutout
groove in the shaft is located within
r 45 degrees of the line extending from
the marking in the 180-degree opposite
direction.
If the cutout groove is within the
allowable angle, the position of
encoder phase Z is appropriate.
If the cutout groove is outside the
allowable angle, the position of
encoder phase Z must be readjusted.
Correct the position as specified on the
next page [procedure 2].
