Simulation of an inverter axis

This simulation corresponds to an inverter axis and can be used to replace a real inverter drive. For this purpose, compatible mapping elements are provided and a behavior very similar to that of a real axis is emulated.

Implementation of a simulated inverter axis

A simulation requires an implementation that can run in one of two places:

in the same context as the control implementation
in a separate runtime or even on a separate CPU

Implementation in both contexts is recommended as described below:

Name	Type	Description
`{attribute 'TcContextName':='FastTask'}`		Instructs `FB_SimCoE402_Inverter` to be updated in a specific task. In this case it must be the calling task that executes the `Cyclic()` method of the simulation block.
`fbInvAxisSim`	FB_SimCoE402_Inverter_Xyz	Creates an instance of the simulation FB.
`bInvAxisSimGoError`	BOOL	Creates a signal for the simulation to report an error state and request a reset procedure.

Range of supported inverters

The term FB_SimCoE402_Inverter_Xyz above must be replaced by one of the following options:

FB_SimCoE402_Inverter_VM

FB_SimCoE402_Inverter_CSVM

Initialization of a simulated inverter axis

In the startup phase, it is necessary to implement an initialization sequence as described below.

IF NOT bInitialised AND bSimulation THEN
    fbInverterSimDS402.CycleTime := 0.002;
    fbInverterSimDS402.MaxTurnRate := 1380.0;
    fbInverterSimDS402.MinTurnrate := 45.0;
    fbInverterSimDS402.RampTime := 2.0;
    fbInverterSimDS402.OutputFactor := 1.0;
    fbInverterSimDS402.ReferenceLoad := 100.0;
END_IF

	The parameters must correspond to the behavior of the simulated device, not to the intended use.
