Example of P/PI conversion by torquecommand
Using PI control at all times without using P/PI conversion during speed control results in
accumulation of the integral term during acceleration/deceleration, which in turn results in
overshoot and longer position determination time. By using appropriate P/PI conversion
mode, you can reduce the determination time. The figure below shows an example of
conversion mode by torque command.
