5.2.3 Default Tags used in Drive Application Software
5.3 DiamCalc JSR Instruction
5.3.1 Input Parameters
5.3.1.1 CalcEnbl – In 1
Enter an application tag for the Diameter Calculator Enable input parameter
(DiamCalc - In1). (See section 4 for guidelines on programming this tag.) If the
Measured Diameter Input is always used, enter '0' for the Diameter Calculator
Enable input parameter.
5.3.1.2 CalcEnblThresh_FPM – In 2, CalcUpdate_Rev – In 3
Enter an application tag for the Diameter Calculator Enable Threshold and the
Diameter Calculator Update Interval input parameters (DiamCalc – In2, In3). If
the Measured Diameter Input is always used, enter ‘0.0 for both the Diameter
Calculator Threshold and the Diameter Calculator Update Interval. The Diameter
Calculator Threshold and the Diameter Calculator Update Interval are typically
configured with tags that can be tuned on-line.
5.3.1.3 LineSpeed _FPM – In 4
Enter an application tag for the Line Speed input parameter (DiamCalc - In4). If
the application tag values are not in units of FPM and RPM, add a rung to the
Main routine that will scale the tag values to FPM and RPM. (See section 4 for
guidelines on programming these tags.)
