1-5-3. Replacing the Y-Axis Limit Sensor and the Y-Axis Home Proximity Sensor
䠄KE-1070C/2070C䠅
If only the sensor is replaced, it is not necessary to adjust the position.
If the sensor is replaced together with the bracket, it is necessary to adjust the position.
(1) Loosen the screw fixing the Y-limit sensor bracket and make the adjustment so that the
distance from the end face of the linear way is that shown in the figure below. After the
adjustment has been completed, tighten the screw firmly.
(2) For adjustment in the vertical direction, make the adjustment so that the clearance
between the Y-MSW bracket mounted on the X-frame end L and sensor surface is 0.8 to
1.5 mm (target: 1.0 mm), and then tighten the screw.
Front (Y-negative limit sensor) Distance between the front end of the linear way and the
center of the sensor: 102.5 mm
Front 2 (Y home proximity sensor) Distance between the front end of the linear way and the
center of the sensor: 117.5 mm
Center (Y-positive limit sensor) Distance between the rear end of the linear way and the
center of the sensor:
334 mm (E-size 334 mm)
Clearance between the limit sensor and the dog 0.8 to 1.5 mm (target: 1.0 mm)
