Replacing The Limit Sensor And Origin Near Sensor; Replacing The X-Axis Limit Sensor And The X-Axis Home Proximity Sensor - JUKI KE-3010 Maintenance Manual

1-3. Replacing the Limit Sensor and Origin Near Sensor

1) When replacing only the sensor, it is not necessary to adjust the position.
2) When replacing the sensor together with the bracket, it is necessary to adjust the position.
∗ The home position of the X-axis is the Z-phase of the magnescale. Therefore, there is no
home position sensor for the X-axis.

1-3-1. Replacing the X-Axis Limit Sensor and the X-Axis Home Proximity Sensor

1) Loosen the screw fixing the X-limit sensor bracket and make the adjustment so that the
distances from the X-frame L and R are those shown in the figure below. After the
adjustment has been completed, tighten the screw firmly. (See Figure 1-3-1-1 (M and L
board specifications) and Figure 1-3-1-2 (XL board specifications).)
