1 Installation
(3) Installing the sensor section
[1] Prepare the notched fitting section at the machine side's installation
position to be of the specified dimensions in advance.
[2] With the sensor installation seat's R section butted against the
notched fitting section, fix the sensor installation seat with a
mounting screw (M4 × 0.8 screws). A locking agent should be
applied on the mounting screw before it is tightened.
[3] Fix the sensor with its R section butted against the notched fitting
section so that the position relation between the detection gear and
sensor is kept constant. This ensures favorable accuracy of the
sensor installation.
[4] Keep the deviation of the sensor center and outer diameter center of
the detection gear to ±0.25mm or less. If the center deviation cannot
be directly measured, set so that the dimension from the sensor
installing surface to the outer diameter edge of the detection gears is
19.0±0.25mm. (Some detection gears have thickness at the inner
diameter section.)
[5] Make sure that force is not constantly applied on the sensor's lead
wires.
[6] Check the gap between the encoder sensor and the gear (0.3±0.05mm).
POINT
To install the sensor section, the notched fitting section on the machine side must have the specified dimensions.
The sensor's installation accuracy is assured by adjusting the outside dimensions of the notched fitting section.
