3-3 Absolute reset procedures

WARNING

Serious injury might occur from physical contact with the robot during opera- tion.

Never enter within the robot movement range during absolute reset.

The operation procedure using the MPB is described next. (Press the ESC key on the MPB if you want to return to the preceding step.)

See the "YAMAHA robot controller owner'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 touch- ing 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 R-axis for absolute reset. (R-axis: M4)

To perform absolute reset on all axes, select "ALL" with the F11 (LOWER+F1) key.

!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.

6)Confirm that the R-axis, to perform absolute reset, is at a position on the plus side of the origin (See Fig. 4-1, Fig. 4-4 ).

If it is not at the plus side, then press the jog key to move the target axis to the plus side.

When performing absolute reset for the other axes at the same time, confirm that the other axes are also at an appropriate position. (Refer to procedures for absolute reset of other axes)
