General Information
The main velocity controller parameters are the proportional gain Kp (S-0-0100) and the integral action time Tn (S-0-0101).
On selection of the motor default values are set, which enable the motor to be operated safely without load. During commissioning the two parameters should be adjusted in order to find a good compromise between drive responsiveness (controller bandwidth) and noise generation. The method described below initially determines the stability limit of the control loop. The value determined for the gain is then multiplied with a field-proven factor, based on the rules of Ziegler and Nichols, in order to obtain a stable control loop. | |
If the bandwidth of the control loop turns out to be inadequate for the application, other methods should be used. A description of these methods would be beyond the scope of this documentation. | |
