Src Disengage Position
Only one of the two permanent enables can be given. If the permanent
enable signal is given, engaging/disengaging action is performed every time
the engaging position is reached again.
The engaging/disengaging action must be completed at the latest in the
greatest possible axis cycle of the ACL max master axis in order to already
recognise the next engaging position again in the following ACL.
If the permanent signal is output continuously the engaging/disengaging
action is only performed once when it first reaches the engaging position.
After this, the drive remains engaged or disengaged respectively.
Special configuration U475 = 11 and U601 > 0 (Variable Ramps):
Acceleration ramp and deceleration ramp can be adjusted independently of
each other.
The position at which the constant travel phase of engaging/disengaging 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.
