Adjustment of RT Axis Belt Tension
[Necessary jig]
• Tension meter
[Preparation before work]
1 Put white marking on 4 locations on the RT
axis belt in the same interval from the front
of the unit.
2 Set the tension meter.
WEIGHT : 2.5 gf/m
WIDTH : 15 mm
SPAN : 92.7 mm
MIC GAIN : Turn up the volume to a position just
before the lamp lights up.
For the detailed operating method of the
tension meter, refer to the manual at-
tached to the tension meter.
3 Measure the tension on the white marked 4
locations on the RT axis.
1. Place the measuring terminal of the
tension meter on the center between
the both pulleys.
2. Knock the RN axis belt with finger,
then tension value on the belt is dis-
played on the tension meter.
3. Measure the tension on the 4 measuring points on the RT axis belt, and check the maxi-
mum value and average value of the tension.
<Standard>
Maximum value: 7.8 kgf (76.4 N)
Average value: 7.14 to 9.18 kgf (80 ±8 N)

4 If the tension of the RT axis belt is out of the
standard, adjust the tension.
1. Loosen the mounting bolts (4-C4 x 20)
for the RT axis motor bracket from the
back of the unit.
2. Remove the nozzle omission detection
sensor amplifier located on the side of
the head part.
Tension adjustment screw for the RT axis belt is
seen.
3. Turn the tension adjustment screw for
the RT axis belt to adjust the belt ten-
sion.
The belt is tensioned by turning the tension ad-
justment screw clockwise, and the belt is loos-
ened by turning it counterclockwise.
4. Measure the tension on the 4 locations on the RT axis belt by using tension meter to check
that the maximum value and average value of the tension are within the standard.
5. After adjusting the tension, fasten the RT axis motor mounting bolt with a torque of 300
cN•m.
6. Return the nozzle omission detection sensor amplifier to the previous position.
