1-5. Replacing the Limit Sensor and the X-Axis Home Position Sensor
If the sensor is replaced together with the bracket, it is necessary to adjust the position.
If only the sensor is replaced, it is not necessary to adjust the position.
1-5-1. eplacing the X-Axis Limit Sensor and the X-Axis Home Position Sensor R
If the sensor bracket is removed, carry out the following adjustment.
If only the sensor is replaced, the adjustment is not needed.
c 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 above. After the adjustment
has been completed, tighten the screw firmly.
d For adjustment in the to-and-fro direction, make the adjustment so that the clearance
between the X-MSC bracket mounted on the rear of the head plate and sensor surface is 0.8
to 1.5 mm (target: 1.0 mm), and then tighten the screw.
