0: exact positioning "off", Look Ahead "on".

Y Activation of exact positioning with tolerance margin monitoring. The
programmed value does not have any meaning.
The G60 function is used to effect the behavior of the path control at the end
of a block of a traversing block. The basic setting is "Genauhalt ohne
Schleppabstandsüberwachung" (Exact positioning without tolerance
margin monitoring).
Exact positioning without tolerance margin monitoring:
The target position of the block is approached via a deceleration ramp. The
size of the ramp is defined in machine constants. The path speed at the end
of the block is "0".
Exact positioning with waiting time:
The target position is approached analog to exact positioning. At this
position, the time programmed under X has to elapse before the block is
ended.
Exact positioning with tolerance margin monitoring:
After the target position has been reached, the control waits until the
tolerance margin of the involved axes is within the configured exact
positioning window (MK_SCHLEPPGENAUHALT). The maximum waiting
time can be programmed for X, 10 seconds are preset.
Exact positioning "off":
The target position of the block is approached with the programmed speed
if another traversing block follows. If the speed of the following block is
lower, the speed is decelerated to this speed at the end of this block. The
speed at the end of the block is effected by the profile course, i.e. the
transition angle of the two blocks ("Look Ahead").
The deceleration takes place via a ramp. If no other traversing block follows,
the target position is approached analog to "Genauhalt ohne
Schleppabstandsüberwachung" (Exact positioning without tolerance
margin monitoring).
G60 X0 Exact positioning (with "Look Ahead") should now be switched off with
immediate effect.
