As long as the permanent enable = 1 (U475=0 in the standard configuration),
procedure is as per following differentiation of cases:
U611
slave
< U601 ==> The engaging/disengaging action is carried out again
each time the couple position is reached.
U611
slave
= U601 ==> The engaging/disengaging action is only carried out
once the first time the couple position is reached.
After this the drive is engaged or disengaged.

Configuration of engaging/disengaging U475 (from version 1.6)
Standard configuration U475 = 0 or U601 = 0:
The position at which the constant travel phase of engaging is finished
results from the engage position and the engaging/disengaging length.
The disengaging position is not taken into account.
Special configuration U475 = 1 and U601 > 0:
The position at which the constant travel phase of
engaging is finished is determined exclusively by the disengaging
position. The engaging/disengaging length is not taken into account
but it must be set greater than the desired total length of the
acceleration/deceleration ramp.
.01 (822)
Src disengaging position
From version 1.6 the following applies with regard to the
engaging/disengaging special configuration (U475=1):
Only one of the two constant enables can be given. If the
constant enable signal is given, engaging/disengaging action is
performed every time the engaging position is reached again.
If the constant enable signal is given continuously, engaging/
disengaging is only performed once when it first reaches the
engaging position.
After this, the drive remains engaged or disengaged
respectively.
