The total length of the acceleration/deceleration ramp U610 must not
be more than the engaging/disengaging length U611. The
engaging/disengaging length U611 must be at least as long as the total
length of the acceleration/deceleration ramp U610.
From MASTERDRIVES version 1.6 as an alternative to the
engaging/disengaging length, a disengaging position (special
configuration U475=1) can also be specified, at which the constant
travel phase of the engaging action is completed (see also function
diagram 834a, column 1, note <3>).
From MASTERDRIVES version 2.1, in addition to the disengaging
position the acceleration and the deceleration ramp can also be
specified differently (special configuration U475 = 11, see also function
diagram 834b, column 1, note <4>).
If the disengaging position (DISENG) lies before the total of
acceleration starting point (ENG) and deceleration ramp end (ACC-RA),
the point ((ACC-RA') or (DEC-RA')) is determined as a result thereof
(from MASTERDRIVES version 2.2 with special configuration
U475=111, see also function diagram 834c, column 1, note <4>).
