FM – Diameter Calculation
Drive Application Software – page 21 of 30
5.3.1.4 SpeedMotor_RPM – In 5, GearRatio – In 6
Enter application tags for the Motor Speed and Gear Ratio input parameters
(DiamCalc – In5, In6). The Gear Ratio is typically configured with a tag that can
be tuned on-line. Since diameter rate is a function of Motor Speed and Gear
Ratio, Motor Speed and Gear Ratio should always be configured.
5.3.1.5 DiamMinEC_in – In 7, DiamFR_in – In 8
Enter application tags for the Minimum Empty Core Diameter and Full Roll
Diameter input parameters (DiamCalc – In7, In8). The Minimum Empty Core
Diameter and Full Roll Diameter are typically configured with tags that can be
tuned on-line. The Minimum Empty Core Diameter and Full Roll Diameter limit
the magnitude of the Diameter Calculator return parameters. Build-Up Ratio is a
function of Minimum Empty Core Diameter.
5.3.1.6 DiamMeasEnbl – In 9, DiamMeasInput – In 10, DiamMeasMin_DC –
In 11, DiamMeasMax_DC – In 12, DiamMeasMin_in – In 13,
DiamMeasMax_in – In 14
Enter application tags for Measured Diameter Enable, Measured Diameter Input
[Data Counts], Minimum Measured Diameter [Data Counts], Maximum Measured
Diameter [Data Counts], Minimum Measured Diameter [Inches], Maximum
Measured Diameter [Inches] input parameters (DiamCalc – In9, In10, In11, In12,
In13, In14). If a Measured Diameter signal is not used, enter ‘0’ for Measured
Diameter Enable, ‘0.0’ for Measured Diameter Input, ‘1.0’ for both Minimum
Measured Diameters, and ‘2.0’ for both Maximum Measured Diameters. When a
Measured Diameter signal is used, Minimum and Maximum Diameter tags are
typically configured with tags that can be tuned on-line.
5.3.1.7 DiamPresetCmmd In 15, DiamPreset Val_in – In 16
Enter application tags for Diameter Preset Command and Diameter Preset Value
input parameters (DiamCalc – In15, In16). If the DiamPreset routine is used,
enter the tags used as return parameters in the DiamPreset JSR instruction. If
the DiamPreset routine is not used, enter the appropriate application tags.
Measured diameter can be used as a preset by configuring the tag used for the
Measured Diameter input parameter (DiamCalc – Ret5).
5.3.1.8 DiamRate_inRev – In 17, DiamIncEnbl – In 18, DiamDecEnbl – In 19
Enter application tags for Diameter Rate Limit, Diameter Calculator Increase
Enable and Diameter Calculator Decrease Enable input parameters. These
parameters are typically configured with tags that can be tuned on-line.
5.3.2 Return Parameters
5.3.2.1 DiamCalc_in – Ret 1, RadiusCalc_ft – Ret 2
Enter application tags, for the Calculated Diameter and Calculated Radius return
parameters.
5.3.2.2 BuildUpRatio – Ret 3, BuildUpRatioRec – Ret 4
Enter application tags, for the Normalized Diameter and Reciprocal of Normalized
Diameter return parameters (DiamCalc – Ret3, Ret4).
5.3.2.3 DiamMeas_in – Ret 5
Enter an application tag, for the Measured Diameter return parameter (DiamCalc
– Ret5). If the Measured Diameter is used to preset the Diameter Calculator and
the Diameter Preset routine is used, enter this tag name for the one of the Preset
Value input parameters. If the Measured Diameter is used to preset the Diameter
Calculator and the Diameter Preset routine is not used, enter this tag name for the
Diameter Preset Value input parameter (DiamCalc – In16).
5.3.2.4 Constant_RPMperFPM – Ret 6
Enter an application tag, for the Calibration Constant return parameter.
