Description
Presetting 0 Switches to the positioning quality class (1...6) set in the applica
tion data.
Fast stop
1)
1 Fast stop without damping time
Output MC_A/MC_B or RC_A/RC_B always supplies a 1−signal
when the axis first enters the range of the positioning tolerance
(see Fig.7/11).
2 Fast stop with damping time
As 1, but there is still a damping time
2)
after the axis enters the
range of the positioning tolerance, before the relevant output
supplies a 1−signal (see Fig.7/12).
Exact stop 3 Exact stop without damping time
Output MC_A/MC_B or RC_A/RC_B always supplies a 1−signal
when the specified axis is in the positioning tolerance for the com
plete duration of the monitoring time
3)
(see also Fig.7/13). If the
axis leaves the tolerance range before the monitoring time ex
pires, the monitoring time will be reset.
4 Exact stop with damping time
As 3, but there is still a damping time
2)
after the monitoring
time
3)
expires, before the relevant output supplies a 1−signal
(seealso Fig.7/14).
5 Exact stop with end speed control
As 3, but for the duration of the monitoring time
3)
the drive must
also stand almost still in the range of the positioning tolerance
(end speed control)
4)
.
6 Exact stop with damping time and end speed control
As 5, but after the monitoring time
3)
expires, there is still a
damping time
2)
before the relevant output supplies a 1−signal.
1)
In positioning quality classes 1 and 2 the adaption has no effect, see appendix B.
2)
The damping time lasts 200 ms. If the tolerance range is left before the damping time expires, the
damping time will not be reset.
3)
The length of the monitoring time can be calculated (see under G60). If the tolerance range is left
before the monitoring time expires, the monitoring time will be reset.
4)
During the end speed control the speed tolerance is 8.0 mm/s (linear drive) or 8.0°/s (rotary
module).
