GetPW
Purpose: Get the parameters of the internal excitation source.
Synopsis : Par = es_call( 'GetPW' )
Description: The function returns the vector containing the parameters of the
internal signal generator currently active in the RTK. The vector contains
20 elements. The set of parameters is common for all shapes of signal
waves, but only some values are used by the currently active excitation
source. The internal excitation source may be used as:
•
a source of control value for the DC motor in the open-loop mode,
•
a source of reference angle in the closed-loop mode.
See
: SetPW
Example : Set and read the parameters of the internal excitation source.
Par = zeros( 1, 20 );
Par( 1 : 5 ) = [ 1 -1.2 4.66 0 7 ];
es_call( 'SetPW', Par);
Par = es_call( 'GetPW' )
