Which products are affected?
9300 vector 55…90 kW SW V7.1
Eliminated function restriction?
During operation in the vector control mode with speed feedback the oscillation damping function for eliminating possible oscillations is not required due to the specific control structure. However, in this mode of operation a current oscillation may be caused due to positive feedback effects in the case of drive powers larger than approx. 55 kW. Therefore, the oscillation damping function will automatically be activated (C0234 = 0 %) within the entire power range (0.37…400 kW) if the vector control mode (C0006 = 1) with feedback (C0025 > 1) is set. Adapting the oscillation damping later on is still possible by means of the codes C0234, C0235 and C0236.
