Functional description
A resolver error is primarily caused by differences in the inductance values for the resolver's sine and cosine tracks and/or by the failure of these tracks to magnetise orthogonally to one another. A new command C0002 = 59 enables you to measure both resolver tracks automatically at speeds of 500[rpm] or above. Once resolver identification is complete, two amplification factors are entered in codes C2862/1 and C2862/2 for the sine and cosine tracks, and any applicable angle correction value is also entered in C2863.
As well as establishing the amplification factors and angle errors, calculations are also carried out to determine whether the quality of the resolver signal will permit an increased dynamic response as regards the resolver evaluation. In a related step, a dynamic expansion value is entered in the newly created code C0417, if applicable.
The calculated resolver correction values can be disabled via the other new code C0418 = 0.
Applications
Applications with a resolver as a feedback signal, where the quality of the feedback signal needs to be improved (synchronous operations, applications with excellent speed follower behaviour)
