Auto−profile With auto−profile positioning, setpoint value curves for path,
speed and acceleration are generated by the CMAX. These
should enable reproducible, fast and overswing−free moveĆ
ment towards the setpoint position.
Unassigned profile When positioning with unassigned profile, the setpoint value
curves are calculated on the basis of the setpoint values proĆ
grammed by the user for position, speed and acceleration.
The setpoint positioning time is the sum of the individual
times of the following phases (see Fig. B/1):
ć Acceleration phase
ć Braking phase
ć Phase of consistent movement
Note that the programmed speed and acceleration values are
automatically limited to implementable values depending on
the positioning stroke. The implementable maximum values
are ascertained by the CMAX individually for each axis during
the identification travel.
