4 If the tension of the RT axis belt is out of the
standard, adjust the tension.
1. Loosen the mounting bolts (4-CP4 x
18) for the RT axis motor bracket from
the back of the unit.
2. Turn the tension adjustment screw for
the RT axis belt to adjust the belt
tension.
The belt is tensioned by turning the tension
adjustment screw clockwise, and the belt is
loosened by turning it counterclockwise.
3. 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.
4. After adjusting the tension, fasten the RT axis motor mounting bolt with a torque of 300
cN･m.

Adjustment of RNF/RNR Axis Belt Tension
[Necessary jigs]
• Tension meter
• RN Axis belt tension Jig
[Preparation before work]
1 Put white marking on 4 locations on the RN
axis belt in the same interval from the front
of the unit.
2 Set the tension meter.
WEIGHT : 2.5 gf/m
WIDTH : 9 mm
SPAN : 96.0 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 attached to
the tension meter.
3 Measure the tension on the white marked 4
locations on the RN 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
displayed on the tension meter.
3. Measure the tension on the 4 measuring points on the RN axis belt.
