Mounting CALSET Bolts on the 4th Axis

To CALSET the 4th axis, you need to mount a CALSET bolt on the axis. As illustrated below, the CALSET bolt is built in the robot unit, so remove it and set it up into the specified position. After completion of CALSET, put it back into place.

Notes for 4th Axis CALSET

1. Remove the CALSET bolt from the robot and attach it to the 4th axis shaft to use it as a mechanical stopper for the T-axis.
   Appropriate tightening torque for the bolt is between 0.5 and 1.5Nm.
   

   Be sure to remove the CALSET bolt after completion of CALSET.

   Be sure to use the CALSET bolt built in the robot unit when performing CALSET.

2. Rotate the 4th axis shaft to the CALSET position by moving the stopper with hand.
   (Pushing torque: 0.5Nm or less)

Never push with too large torque.

3. In case of the dust- & splash-proof type, perform 4th-axis CALSET after removing the lower bellows.
