Lenze 9300 - Influence of Precontrol Values (POS-NOUT-GAIN, POS-MOUT-GAIN); New Travel Profile Parameters During Positioning; Override

Function library
7-63
L
EDSVS9332P-D21 EN 3.0
7.5.9.3 Override
Purpose
• Dynamic change of the profile parameters (speed and acceleration).
Example: Setting the traversing speed depending on the master speed.
Function
• Dynamic adaptation of traversing and final speed (POS-V-OVERRID).
• Dynamic adaptation of acceleration and deceleration (POS-A-OVERRID).
• The override inputs are considered before each positioning process. With the input
POS-PARAM-RD this is also possible during the process (see chapter 7.5.9.4)
– The parameter values are reduced according to the % values at the override inputs.
• In manual operation the override inputs are always effective.
– Note: Only positive override values are effective, negative values will be evaluated as zero.
7.5.9.4 New travel profile parameters during positioning
Purpose
• Change of the target position, speed or acceleration during positioning.
Function
• LOW-HIGH edge at POS-PARAM-RD immediately accepts - also while positioning is running -
new profile parameters from the variable tables VT.
Profile : Target position, traversing speed, acceleration, deceleration, final speed, V override,
A override, POS-S-RAMPS (limited).
– With constant HIGH level: new profile parameters are accepted every 10 ms.
Tip!
Firmware version < 2.5: Not effective in stand-by operation.
Firmware version
≥ 2.5: Also effective in stand-by operation.
7.5.9.5 Influence of precontrol values (POS-NOUT-GAIN, POS-MOUT-GAIN)
Purpose
• Reduction of the influence of precontrol on speed and torque controller.
Function
• Adaptation of the speed precontrol (POS-NOUT) to the speed controller (MCTRL-N-SET)
(POS-NOUT-GAIN, default setting: 100 %)
• Adaptation of the torque precontrol (POS-MOUT) to the torque controller
(POS-MOUT-GAIN, default setting: switched off)
• 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.
