5.3 JLossComp JSR Instruction
5.3.1 Input Parameters
5.3.1.1 Line Speed Reference
Enter an application tag for the Line Speed Reference input parameter
(JLossComp – In1). If the application tag value is not in units of FPM, add a rung
to the Main routine that will scale the tag value to FPM.
5.3.1.2 Line Speed Reference Rate
If available, enter an application tag for the Line Speed Reference Rate input
parameter (JLossComp – In2). If the application tag value is not in units of FPM
per second, add a rung to the Main routine that will scale the tag value to FPM per
second.
5.3.1.3 Enable Differentiator
Enter an application tag or immediate value for the Enable Differentiator input
parameter (JLossComp – In3).
5.3.1.4 Number of Differentiator Moving Average Samples
Enter an application tag for the Number of Differentiator Moving Average Samples
input parameter (JLossComp – In4).
5.3.1.5 Normalized Diameter
Enter an application tag for the Normalized Diameter input parameter
(JLossComp – In5). This tag must be normalized such that the value is equal to
1.0 at minimum empty core diameter. If the Diameter Calculator Function Module
is used, enter the tag used as a return parameter in the DiamCalc JSR instruction.
For constant diameter applications, an application tag or an immediate value of
1.0 can be used.
5.3.1.6 Translational-to-Rotational Conversion Constant
Enter an application tag for the Translational-to-Rotational Conversion Constant
input parameter (JLossComp – In6). This conversion constant must be calculated
using the minimum empty core diameter. If the Diameter Calculator Function
Module is used, enter the tag used as a return parameter in the DiamCalc JSR
instruction.
5.3.1.7 Motor Base Speed
Enter an application tag or immediate value for the Motor Base Speed input
parameter (JLossComp – In7).
5.3.1.8 Total Reflected Inertia [seconds]
Enter an application tag, for the Total Reflected Inertia input parameter
(JLossComp – In8). If the JCalc routine is used, enter the tag used as a return
parameter in the JCalc JSR instruction (JCalc – Ret4).
5.3.1.9 Inertia Compensation Gain
Enter application tags, for the Inertia Compensation Gain Quadrant 1 and 2 and
Inertia Compensation Gain Quadrant 3 and 4 input parameters (JLossComp –
In9, In10).
5.3.1.10 Friction Loss
Enter an application tag for the Friction Loss input parameter (JLossComp –
In11).
5.3.1.11 Windage Loss
Enter an application tag for the Windage Loss input parameter (JLossComp –
In12).
5.3.1.12 MtrTrqRated_lbft
Enter an application tag or immediate value for the Motor Rated Torque input
parameter (JLossComp – In2).
