ADAPT GAIN-[%]**
Adaptive Gain%**
This value represents the amount of gain, as a product with the
Control Gain, that is used to set control loop response.
If Adaptive Tuning is <On>, the value is calculated according the
scale disturbance in ppm/Update, the entered setpoint and the scale
range. This value is a multiplier for the CTRL GAIN.
When the adaptive tuning is <On>, this value is automatically set.
E.g. 100% = good control, 10% = poor control.
Input range: 1 to 100%
Default: 100%
SAMPLE TIME- [msec]**)
Weight Sample Time**
Setting of the SFTs' measuring cycle in milliseconds. The weight loss
is measured using this time interval during feeding. When the
<ADAPTIVE TUNE> is <On>, this value is automatically set. This
value can only be manually set when <ADAPTIVE TUNE> is <Off>.
Input range: 80 to 8,000 msec. Default: 160 msec.
CUTOFF FRQ-[Hz]**
SFT CutOff Frequency**
Cutoff frequency for the SFT internal digital filter. A lower value
represents a more stable weight display albeit slower control
response. When the Adaptive Tuning is <On>, this value is
automatically set. User can change this entry when Adaptive Tuning
is <Off>.
Input range: 0.033 Hz to 9.999 Hz Default: 0.4 Hz
PERT VALUE
Pert Value
Pert Value shows the signal/noise ratio of scale disturbance in
percentage to the setpoint. It is a measure of scale disturbance
relative to setpoint. A low reading is best. If Setpoint is <0>, then the
reading is in grams. See appendix for details of using this value to
determine feeder performance.
Input range: Read only
SPEED MODULAT
Modulation or Speed
Modulation
Note:
Not for vibratory feeders
If <Gear Reduction> input > 0.00, the screw modulation can be
activated. Used only for single screw feeder types. Operating screw
speed needs to be below 60 rpm for modulation to work.
Attention:
An incorrect input of <Gear Reduction> leads to the oscillation in
massflow output.
Input range: On or Off
Default: Off
Note:
This parameter is displayed at the KSU-II/KCM only if the proper
motor drive is installed and the proper gear reduction is entered. This
parameter is not used for vibratory drives.
