 Program the new Wind Up Coefficient in the spindle interface and Apply.
 Run a new tightening and look at the trace again. Now, the curve should look something like the
example shown below. As you can see now is there a lash in the socket of about 0.8 deg and then
the torque increases to 45 Nm without moving the bolt and this is the goal.
Note! When external equipment is connected on the spindle WindUp is likely to be calculated - but the
values should be entered using the External Equipment parameters, see Application External
Equipment on the Spindle Set Up form.
