(8) Adjusting the Z phase and A phase difference

[1] Stop the motor, and make sure that the detection gears are not rotating. The sensor could be

damaged if adjustments are carried out while the gears are rotating.

[2] Using a clearance gauge, adjust so that the gap between the sensor direction surface and the

detection gears’ circumference is 0.15±0.01mm, and loosen the sensor fixing screw.

[3] The phase difference of the Z phase to the A phase can be adjusted by rotating the sensor as

shown on the right. At this time, rotate the sensor a little bit while using the marking lines on

the sensor and installation seat as a guide.

[4] Tighten the sensor fixing screw so that the sensor

does not move, and confirm that the gap between the

sensor detection surface and detection gears'

circumference is 0.15 ± 0.01mm. Then, rotate the

gears and confirm the phase difference as explained

above.

[5] When the phase difference is within the tolerable

range, apply a locking agent on the sensor fixing

screw, and then fix the sensor. Check the gap again

after fixing the sensor.

4-1 D/A output specifications for spindle drive unit

The spindle drive unit has a function to D/A output each control data. The spindle adjustment data

required to set the spindle parameters matching the machine can be D/A output. The data can be

measured with a hi-corder or oscilloscope, etc.
