4.3.4 Preset1Val_in
The value of Preset1 entered in inches of roll diameter. This value will be sent to the
diameter calculator when Preset1Cmmd is set high.
Usage – Set this vale for the smallest roll diameter used when presetting the
diameter calculator in Winder applications. For Unwind applications, set to the
largest diameter used when presetting the diameter calculator.
4.3.5 Preset2Val_in
The value of Preset2 entered in inches of roll diameter. This value will be sent to the
diameter calculator when Preset2Cmmd is set high.
Usage – Set this value to the diameter in inches to be used for Preset2Cmmd.
4.3.6 Preset3Val_in
The value of Preset3 entered in inches of roll diameter. This value will be sent to the
diameter calculator when Preset3Cmmd is set high.
Usage – Set this value to the diameter in inches to be used for Preset3Cmmd.
4.3.7 PresetIncCmmd
The diameter preset increase input is used to increase the calculated diameter. The
function of this input is inhibited when the EnablePresets input is low. The rate of
change for this increase in diameter is set by the DiamIncDecRate_inSec input.
Usage – This input should be connected to a dynamic command that can be set high
when the operator wishes to increase the diameter calculator, using an increase
pushbutton.
4.3.8 PresetDecCmmd
The diameter preset decrease input is used to decrease the calculated diameter.
The function of this input is inhibited when the EnablePresets input is low. The rate
of change for this decrease in diameter is set by the DiamIncDecRate_inSec input.
Usage – This input should be connected to a dynamic command that can be set high
when the operator wishes to decrease the diameter calculator, using a decrease
pushbutton.
4.3.9 PresetIncDecRate_inSec
The diameter increase/decrease rate input is set in inches of diameter change per
second. This parameter sets the rate of change for the DiamInc and DiamDec
inputs. To aid in manual adjustment of the calculated diameter, the rate of change
will be increased by 3x when the DiamInc or DiamDec inputs are high for more than 3
seconds. If the inputs are set low and then high again, the 3 second delay will
repeat. This configuration allows for precise adjustment of the diameter preset value
and quick changes if the amount of change to be made is significant.
Usage – Adjust this input for a value that allows the operator to accurately adjust the
diameter preset as desired. Recommend initial setting of 0.5 to 1 in/Sec.
4.3.10 DiamPresetCmmd
This return parameter is used to activate the preset function of the DiamCalc routine.
This output will be set high when the EnablePresets is high and one of the preset
inputs are high. This output will command the DiamCalc routine to read the value in
DiamPresetVal_in as the actual diameter.
Usage – The tag entered in the DiamPreset JSR instruction for this return parameter
should be entered as an input parameter to the DiamCalc JSR instruction.
