When there is oscillation, rollback, or other control problems, adjust the parameters as specified by the control method.
V/f Control and Closed Loop V/f Control shows only the frequently adjusted parameters.
Note:
Torque and speed response for high-resistance and high-slip motors are slow. Adjust the torque and speed response to increase them. Low impedance (low-slip) motors will hunt and oscillate. Adjust the torque and speed response to increase them.
