DANGER

To prevent any trouble caused by accidental machine start, always

shut-down the power before starting the maintenance and

adjustment work.

The XY-axis uses a very strong magnet.

• Do not put any metallic object close to the magnet surface. Once the

magnet attracts a metallic object, this object cannot be removed due to

strong magnetic force.

• Before starting the maintenance work, take off precision portable devices,

such as a wrist watch from your body.

• Do not allow personnel who uses a precision medical device, such as an

artificial cardiac pacemaker, etc to carry out the maintenance work.

1-1. Replacing the Magnescale

(1) Detach the magnescale head from the bracket.

(2) Peel off the old magnescale.

(3) Degrease the magnescale mounting surface and magnescale completely.

Note 1: Before replacing the magnescale, put the magnescale near the machine and leave

it for 1 hr. or longer to make the temperature of the magnescale similar to that of the

machine.

Note 2: “Mecha fine mate” is recommended for the degreasing agent.

Note 3: Deviation amount when compared to the specified value of the magnescale in the

X-direction:

0.1 mm or less.

Note 4: Do not put any magnet, such as magnetized screwdriver or support pin close to the

magnescale. Doing so may cause the magnescale to malfunction.

Note 5: The magnescale has a correct orientation. Affix it in the direction shown in the figure

below.

1-1-1. X-Axis Magnescale Affixing Position

(1) Affix the magnescale while guiding it using the X_MSC install jig.

The affixing starting line for the LF/RF is indicated by the mark-off line on the left side when

viewed from the front and that for the LR/RR is indicated by the mark-off line on the left when

viewed from the rear.

Adjust the position of the Z-phase marking on the magnescale side to the mark-off line, and

then affix the magnescale.

Specification value: Magnescale affixing position (Displacement in the direction parallel with the
