● Each axis’ movement formular
When the slant axis’ movement amount is Ya ， and the quadrature axis’ movement is Xa, the
system realizes the control by the following expressions.
The slant axis’ calculation formular:
θ cos

Ya
=
the quadrature axis’ calculation formular:
θ tan
× × − =
Yp C Xp Xa
Note: The coefficient C becomes 2 when the quadrature axis is specified with a diameter, and becomes 1
when the quadrature axis is specified with a radius.
Relationship between a slant axis and a quadrature axis is shown in Fig. 2-84:
