CAUTION
IF THE SELECTED AXIS DOES NOT SHOW A FIGURE BETWEEN 26 AND
74, THEN AN ERROR MESSAGE, "ABS.RESET POSITION ERROR"
APPEARS DURING THE NEXT STEP AND ABSOLUTE RESET IS
DISABLED.
9) A message "Reset ABS encoder OK?" appears, so press the F4 (YES) key
if okay to reset at that position.
CAUTION
IF "ALL" WAS SELECTED IN 6) THEN THE X-AXIS, Y-AXIS OR R-AXIS
CAN BE RESET IN SERVO-OFF. HOWEVER THE SERVO MUST BE ON
WHEN PERFORMING ABSOLUTE RESET OF THE Z-AXIS. SEE "3-3-2-3
ABSOLUTE RESET WITH SERVO ON (NEW RESET)" FOR INFORMATION
ON PERFORMING Z-AXIS ABSOLUTE RESET.
10) After absolute reset is complete, set the robot to servo-on and move all
robot axes to their "0" pulse positions. To move axes to their "0" pulse
positions, see Chapter 4, "Point trace function" in the "OMRON Robot
Controller User's Manual".
CAUTION
BEFORE AFFIXING THE ORIGIN POSITION STICKERS, BE SURE TO
MOVE ALL ROBOT AXES BACK TO THEIR "0" PULSE POSITIONS.
OMITTING THIS STEP MAY MEAN THAT THE NEXT ABSOLUTE RESET
MIGHT BE INCORRECT.
11) After moving all the axes back to their "0" pulse positions, press the emer-
gency stop button and affix the supplied origin position stickers to the up-
per and lower areas of the X-axis, Y-axis, and R-axis. Use these marked
positions to perform an absolute reset if it is needed in the future. (See Fig.
4-5 to Fig. 4-8.)
Use alcohol, etc. to remove any grease or oil from the surface where you
will affix the stickers. After the surface dries attach the stickers securely.
CAUTION
THE DEVIATION BETWEEN THE ORIGIN POSITION MARKS MUST BE
WITHIN A SPECIFIED RANGE (REPEATABILITY TOLERANCE) WHEN
PERFORMING THE ABSOLUTE RESET AT THE SAME POSITION AS THE
PREVIOUS ABSOLUTE RESET. (SEE FIG. 4-4)
WHEN AFFIXING AN ORIGIN POSITION STICKER, ALIGN IT PRECISELY
WITH THE UPPER AND LOWER STICKERS OF THE JOINT AREA SO
THAT THE ABSOLUTE RESET POSITION CAN BE EASILY CHECKED THE
NEXT TIME AN ABSOLUTE RESET IS PERFORMED.
