3-3 Absolute reset procedures
3-3-1 Sensor method (X-axis, Y-axis, and R-axis)
The operation procedure using the PB is described next. (Press the ESC key on
the PB if you want to return to the preceding step.)
See the "OMRON Robot Controller User's Manual" for information on operat-
ing the robot controller.
1) Check that no one is inside the safeguard enclosure and then turn on the
controller.
2) Place a sign indicating the robot is being adjusted, to keep others from
touching the controller switch or operation panel.
3) Set the controller to MANUAL mode, if not in MANUAL mode.
4) Press the F13 (LOWER+F3) key to select "RST. ABS".
5) Select the axis for absolute reset. (X-axis: M1, Y-axis: M2, Z-axis: M3, R-
axis: M4)
To perform absolute reset on all axes, select "ALL" with the F11
(LOWER+F1) key.
6) Check that the absolute reset axis must be positioned at the plus side of the
origin. (See Fig. 4-2.)
If it is not at the plus side, then press the jog key to move the target axis to
the plus side.
7) Since the message "Reset ABS encoder OK?" is displayed, check that there
are not any obstacles in the robot movement range, and press the F4 key
(YES).
WARNING
SERIOUS INJURY MIGHT OCCUR FROM PHYSICAL CONTACT WITH
THE ROBOT DURING OPERATION.
NEVER ENTER WITHIN THE ROBOT MOVEMENT RANGE DURING
ABSOLUTE RESET.
CAUTION
THE Z-AXIS OF THE STROKE END METHOD FIRST RISES DURING THE
ABSOLUTE RESET OF ALL AXES (DEFAULT SETTING). BE CAREFUL
THAT YOUR FINGERS DO NOT GET PINCHED OR CRUSHED BY ANY
SUDDEN MOVEMENT.
