In the setting-up mode, using parameters (velocity, acceleration and deceleration) "endless"
closed-loop position control behavior can be carried-out.
It is possible to make a flying changeover between the two modes.
If continuous acceptance (p2649 = 1) is activated, changes to the MDI parameters are
accepted immediately. Otherwise the values are only accepted when there is a positive edge
at binector input p2650 (setpoint acceptance edge).
Note
Continuous acceptance p2649 = 1 can only be set with free telegram configuration
p0922 = 999. No relative positioning is allowed with continuous acceptance.
The direction of positioning can be specified using p2651 (positive direction specification)
and p2652 (negative direction specification). If both inputs have the same status, the
shortest distance is traveled during absolute positioning (p2648 = "1") of modulo axes
(p2577 = "1").
To use the positioning function, the drive must be in operating mode (r0002 = 0). The
following options are available for starting positioning:
● p2649 is "1" and positive edge on p2647
● p2649 is "0" and p2647 is "1"
– positive edge on p2650 or
– positive edge on p2649
