Matching of Y 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

Y-CCW sensor side (front) 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 LM

guide rail end to the LM guide face

with a scale.

Suppose that the measured value is A.

(Example : 116 mm)

3 Press the emergency stop switch.

Servo is turned off.

4 Stop the Y axis at the boundary position

where the ORG sensor LED in extinguished

condition lights up.

1. Manually move the Y axis backward to

the position where the dog leaves the

ORG sensor.

2. Manually move the Y axis forward lit-

tle 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 LM

guide rail end to the LM guide face

with a scale.

Suppose that the measured value is B.

(Example : 135.5 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 (116 mm) - B (135.5 mm) = C (

19.5 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 (-19.5 mm) + Amount of Z-phase movement (5 mm) = D (-14.5 mm)

Since the present amount of movements is too as large as -19.5 mm against the set amount of movement “5 mm”, the ad-

justment made small 14.5 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 Y axis

to secure working space to loosen the

coupling screws.

2. Loosen the screw M4 on the ball screw

side of the coupling.

3. Measure the distance from the LM

guide rail end to the LM guide face

with a scale. (Example : 134 mm)

Suppose that this measured value is E.

E (134 mm) - D (-14.5 mm) = target dimension (148.5 mm)

4. Move the Y axis by dimension of the difference (D) with set-up movement found in the procedure 6.

Example : Adjust the Y axis so that the distance between the LM guide rail end and the LM guide face is 148.5 mm.

When the Y 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 Y axis to the CCW sensor side (front direction), and if the dif-

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

5. Fasten the screw M4 on the ball screw side of the coupling with a torque driver.

Tightening torque : 3.4N•m

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 LM guide rail end 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
