Matching of X Axis Z-Phase

This section describes a procedure to adjust the Z-phase

position in such a way that the motor stops at the posi-

tion (Z-phase set-up position) where the ORG sensor

detects the dog and then moves by 5 ±1 mm toward the

X-CCW sensor side (left) when origin position return is

performed.

[Procedure]

1 Press the ORG button on the operation panel.

Origin position return is performed.

2 Measure the present Z-phase position.

1. Measure the distance from the frame

end face to the LM guide face on the

left side of the unit with a scale.

Suppose that the measured value is A.

(Example : 122.5 mm)

3 Press the emergency stop switch.

Servo is turned off.

4 Stop the X axis at the boundary position

where the ORG sensor LED in extinguished

condition lights up.

1. Manually move the X axis in right di-

rection to the position where the dog

leaves the ORG sensor.

2. Manually move the X axis in left di-

rection little by little and stop at the

boundary position where the ORG

sensor LED in extinguished condition

lights up.

5 Measure the dog detection position of the

ORG sensor.

1. Measure the distance from the frame

end face to the LM guide face on the

left side of the unit with a scale.

Suppose that the measured value is B.

(Example : 130.5 mm)

By 2 times of measurements, the amount of movements from the dog detection position of an

ORG sensor to the present Z-phase position can be found.

Suppose that the present amount of movement is C.

Example : A (122.5 mm) - B (130.5 mm) = C (-8 mm)

6 The difference between the present mount of movement and the amount of Z-phase set-up

movement “5 mm” is searched for. Suppose that this difference is D.

Example : Present amount of movement (-8 mm) + Amount of Z-phase movement (5 mm)=D (-3 mm)

Since the present amount of movements is too as large as -8 mm, the adjustment made small 3 mm is required of this example.

7 Adjust the Z-phase set-up position.

Adjust the Z-phase set-up position by adjusting the positional relation between the motor and

ball screw.

1. Move the head to the center of X axis

to secure working space to loosen the

coupling screws.

2. Loosen the screw M5 on the ball screw

side of the coupling.

3. Measure the distance from the frame

end face to the LM guide face with a

scale. (Example : 235 mm)

Suppose that this measured value is E.

E (235 mm) - D (-3 mm) = Target dimension (238 mm)

4. Move the X axis by dimension of the difference (D) with set-up movement found in the

procedure 6.

Example : Adjust the X axis so that the distance between the frame end face and the LM guide face is 238 mm.

When the X axis is moved, the coupling should not be moved.

If the difference between the present amount of movements and the amount of Z-phase set-up

movement is positive, move the X axis to the CCW sensor side (left direction), and if the dif-

ference is negative, move it to the CW sensor (right direction).

5. Fasten the screw M5 on the ball screw side of the coupling with a torque driver.

8 Turn the emergency stop switch in the arrow direction to release the emergency stop state.

9 Press the ORG button on the operation panel to perform origin position return.

10 Check the Z-phase set-up position.

1. Measure the distance from the frame end face to the LM guide face with a scale. Suppose

that this measured value is A.

2. Measure the dog detection position of the ORG sensor with a scale.

Suppose that the measured value is B.

Check that a relation is obtained as A (Z-phase set-up position) =B - 5 mm (Z-phase set-up movement amount)

Tolerance level : ±1 mm
