1.3 Backup U/D and Timing Belt
Measure the arrow-marked position with
a digital tensometer and confirm that the
tension becomes "59 to 69 N (6.0 to 7.0
kgf)".
• When the measured tension value
differs from the specified one, adjust
the tension with Motor Bracket 4.
(Rotate the pulley and measure
several spots. Connect the jig and
release the brake.)
Set Value for Tensometer:
Width = 12 mm
Unit Weight = 0.25 gf/cm

Span = 250 mm
1.4 Leveling of Ball Spline
While keeping the motor braked and Phase C detected, use the slot (Timing Pulley S20) to
adjust the dimension (the distance up to the upper surface of Spline Shaft S16) for
"232.0±0.2 mm" and the parallelism of Points A, B, C, and D on the shaft for "0.01 mm or
less".
1.5 Setting Confirmation of Lower Limit Mechanical Stopper
Attach Lower Limit Mechanical Stopper
S29 to Base 1.
At this time, the dimension between the
stopper mounting face of the base and the
stopper rubber end must be "36.0 mm (35.5
to 36.0 mm).

1.6 Flatness Confirmation of Backup Base
(1) Fix the backup base with the bolts (M6L16), SW, and FW so that the positioning pin
can be located outside.
(2) Apply a dial gauge to in Bases a and b and confirm that the total flatness of a and
b is "0.1 mm or less".
