LookDown()

This method translates a slave value to a matching master value. If the value lies between two defined points in the table, the selected operation mode is used for interpolation.

Syntax:

METHOD LookDown : HRESULT
VAR_INPUT
    Slave:              LREAL; 
    SlaveVelo:          LREAL;
    fGuidingValue:      REFERENCE TO LREAL; 
    fGuidingVelo:       REFERENCE TO LREAL;
    TorqueLimiting:     REFERENCE TO LREAL;
END_VAR

Inputs

Name	Type	Description
Slave	LREAL	Primary slave value
SlaveVelo	LREAL	Tertiary slave value Notice Only available in second-order equidistant operation mode
fGuidingValue	REFERENCE TO LREAL	Resulting master value for the requested slave value
fGuidingVelo	REFERENCE TO LREAL	Master value for the requested tertiary slave value. This is determined taking into account the first derivative of the primary slave value Notice Only available in second-order equidistant operation mode
