<p>The present invention relates to a method of supervising a rotation position of a motor, comprising the steps of: receiving (20) analogue resolver signals from a resolver (3) of said motor; A/D-converting (21) the received analogue resolver signals, providing digitized resolver signals; comparing (22) the received analogue resolver signals in a comparator (4) to provide quadrature values of said resolver; determining (26) a primary rotation position of said motor based on said digitized resolver signals; and supervising (27) the primary rotation position by determining (27) a secondary rotation position of said motor based on said quadrature values and comparing said secondary rotation position with the primary rotation position.</p> |
