When having synchronous motors Rho electric complies with the pole posi-
tion actual value or actual value of the commutation angle and the notch po-
sition complies with the pole position offset or commutation angle offset.
n The following applies to the asynchronous motors (Z107.38–, bits 2,1 = 01):

m During the encoderless operation of the synchronous motor the parameter Rho electric
>47.47< is generated from a motor model with current actual values, voltage set val-
ues and motor parameters.
m The encoderless asynchronous motor ASM (Z107.38– bits 2,1 = 01; Z19.52– = 2) be-
ing oriented towards the stator flux, the parameter >47.47< Rho electric has no mean-
ing.
