5) 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 motor-unit affixing bolts.
Recommended tightening torque for adjustment bolts: (M5) 763 N-cm (78 kgf-cm)
Caution: After tightening the bolts to the above torque, tighten them slightly further by making
sure that both pulleys do not move.
6) Install the pulley cover.
Tighten the three hexagon socket head bolts (M3x22) using an Allen wrench of 2.5 mm across flats.
7) 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, adjust parameter No. 22, “Home offset” if you are using an SCON controller. If you are
using an SSEL or X-SEL controller, adjust axis-specific parameter No. 12, “Home preset.” If your controller is
of absolute encoder specification, perform homing after changing the parameter, and then perform an absolute
reset.
