Tension: SS7R: 6.7 kgf
SS8R: 6.9 kgf
4) Adjust the belt tension.
Pass a looped strong string (or long tie-band) around the motor cover and pull it with a tension gauge
to the specified tension. In this condition, uniformly tighten the adjustment bolts.
Recommenced tightening torque for adjustment bolts
SS7R: 2 upper bolts (M4) 377 N-cm (38 kgf-cm)
2 lower bolts (M4) 377 N-cm (38 kgf-cm)
SS8R: 2 upper bolts (M5) 763 N-cm (78 kgf-cm)
2 lower bolts (M4) 377 N-cm (38 kgf-cm)
Caution: Carefully tighten them to the specified torque by making sure the pulleys on both sides do
not move.
5) Install the pulley cover.
With SS7R, tighten the three thin-head screws (M3x6) using an Allen wrench of 1.5 mm across flats.
With SS8R, tighten the three thin-head screws (M4x6) using an Allen wrench of 2 mm across flats.
6) Perform homing using a PC or teaching pendant.
(If the actuator is of absolute encoder specification, an absolute reset must be performed.)
Check for deviation from the initial home position..
If there is a deviation when the SCON controller is being used, use home return offset distance of
parameter No. 22 to make corrections. If the SSEL or the X-SEL controller is being used, use home
preset value of axis-specific parameter No. 12 to make corrections.
For the absolute encoder specification, perform homing
absolute reset after changing the parameter.
