37 FFACC (708)
Set the base velocity whenever you have limited
the bandwidth. Thus you will prevent the control
from not accelerating at all due to the limit set.
FFACC indicates the value with which the accele-
ration feed-forward is completed.
For a normal PID algorithm this value is equal to 0.

38 REGWMAX
The parameters REGWMAX and REGWMIN (39) are
used to turn the position control within defined areas
(control windows) on and off: REGWMAX indicates
the size of the window outside of which the control
should begin again.

REGWMIN indicates the size of the window inside
of which the control is to be deactivated until the
REGWMAX (38) control window is reached again.

4 0 HOM ET YPE
Determines behavior during movement to home:
0 = Moves to reference switch with HOME velocity
and direction, then reverses and slowly leaves
the switch, subsequently moves to the next
index impulse.
1 = like 0, but does not search for index impulse
2 = like 0 but without reversing, rather continues
movement in the same direction out of the
switch
3 = like 1 but without reversing
