Positioning control
3.4.9 Travel profile generator and setpoints
3−62
l
EDSVS9332P−EXT DE 2.0
3.4.9.3 Override
Purpose
l Dynamic change of the profile parameters (speed and acceleration).
Example: Setting the traversing speed depending on the master speed.
Function
l Dynamic adaptation of traversing and final speed (POS−V−OVERRID).
l Dynamic adaptation of acceleration and deceleration (POS−A−OVERRID).
l The override inputs are considered before each positioning process. With the input
POS−PARAM−RD this is also possible during the process (see chapter 3.4.9.4)
The parameter values are reduced according to the % values at the override inputs.
l In manual operation the override inputs are always effective.
Note: Only positive override values are effective, negative values will be evaluated as zero.
3.4.9.4 New traversing profile parameters during positioning (POS−PARAM−RD)
Purpose
l Change of the target position, speed or acceleration during positioning.
Function
l LOW−HIGH edge at POS−PARAM−RD immediately accepts − also while positioning is running −
new profile parameters from the VT variable tables.
Profile : Target position, traversing speed, acceleration, deceleration, final speed, V override, A
override, POS−S−RAMPS (limited).
With a constant HIGH level: new profile parameters are accepted every 10 ms.
Tip!
Firmware version < 2.5: Not effective in stand−by operation.
Firmware version ³ 2.5: Also effective in stand−by operation.
3.4.9.5 Influence of precontrol values (POS−NOUT−GAIN, POS−MOUT−GAIN)
Purpose
l Reduction of the influence of precontrol on speed and torque controller.
Function
l Adaptation of the speed precontrol (POS−NOUT) to the speed controller (MCTRL−N−SET)
(POS−NOUT−GAIN, default setting: 100%)
l Adaptation of the torque precontrol (POS−MOUT) to the torque controller
(POS−MOUT−GAIN, default setting: switched off)
l The precontrol values are reduced according to the % values at the inputs.
Tip!
With dynamic positioning processes, a reduction of the speed precontrol (e.g. to 95%) can be
advantageous for the travelling performance towards the target position.
