12.1.13
P018 Speed Adjust
This parameter allows adjustment to the speed constant for both speed sensors (P015-01 or
P015-02)
2)
. Initially, this parameter displays the dynamic speed of the belt. If thedisplayed speed
is not equal to the actual speed, enter the actual belt speed (f = 0.00).
For speed sensor applications, the value of P015 is automatically adjusted.
For constant speed (terminals 17/18 jumpered) the value of P014 is automatically adjusted.
2)
Not available with BW500/L
12.1.14
P019 Manual Span Adjust
Provides a means for adjustment to the span calibration ( f = 0)
The adjustment value is determined by performing material tests and is subsequently entered
either as a calculation of % change into P598, or as the weight of the material test.
Entry:
1 = % change
2 = material test
Refer to Recalibration (Page 67)
.
12.1.15
P022 Minimum Speed Frequency
Sets the minimum frequency that the speed sensor can reliably read. Signals at low frequencies
are erratic, adversely affecting the performance of the weighing system.
Entry:
1 = 1 Hz (at 1 Hz, it takes 1 s before defaulting to 0 speed)
2 = 2 Hz
f (at 2 Hz, it takes 0.5 s before defaulting to 0 speed)
12.1.16
P080 Display Damping
P080-01 Rate
P080-02 Load
P080-03 Speed
Sets the speed of response to which the displayed readings (rate, load, and speed), and outputs
(alarm and mA
1)
) react to change.Refer to Operation (Page 97) .
Note
Effect of damping (P080
-01) on mA output can be overridden by mA output damping (P220).
The higher the damping value, the slower the response.
Enter damping value, range 0.000
f – 999
1)
Damping is not applicable to the mA output if programmed for PID function (P201 = 4).
