Mount the disk (component 7a or 7b) to the hexagon screws
(component 8) of the coupling (see illustration 19) and tighten
it evenly to the tightening torques specified in table 9.
Screw the hexagon nuts (component 11) onto the setscrews
(component 9 or 10).
Screw the setscrews (component 9 or 10) into the disk
(component 7) or hub part 5AB.
Identify the axial backlash of the entire coupling. It should be
half as big as the axial backlash of the motor. Please make
sure that the permissible axial displacement of the coupling is
not exceeded (see table 11).

Illustration 20
!
The axial limitation of the coupling must in
every case be smaller than the axial backlash of
the motor and big enough to make sure that the
coupling is able to compensate for angular
displacements.
Set the axial backlash of the coupling (see illustration 20).
Dimension x is each half of the axial backlash identified of the
entire coupling. Please make sure that the motor shaft is
located in the magnetic center.
Example:
Axial backlash of the motor
= 4 mm
Axial backlash of the entire coupling
= 2 mm
Dimension x (axial backlash per coupling hub) =
1 mm
Fix the position of setscrews (component 9 or 10) by
countering with hexagon nuts (component 11). Tighten them
evenly to the torques specified in table 10. Protect the
setscrew from turning.
