Over Exciting CooperationProgram ⇒ Special Control Parameters ⇒ Special Parameters⇒ Over-
Exciting Cooperation
This parameter determines the method used to control the rate that the
excitation current is allowed to reach saturation. If Effective is selected, the
preset Torq ue Control or Speed Control settings will determ ine the rate that
the motor reaches excitation sa turation.
