Description
The RK parameter can be used to correct any amplitude difference that may exist between the sine and cosine signals from the resolver. The relationships are as follows:
- RK = 16384 no alteration of the amplitude of the sine signal
- RK < 16384 sine signal amplitude is reduced
- RK > 16384 sine signal amplitude is increased
An incorrect setting of this correction factor will result in velocity/velocity variations (ripple) which are strongly dependent on the position.
The CALCRK command enables an automatic determination of the correction factor RK.
This value will not be changed by a parameter download, since it only depends on the equipment.
