Current loop:
P12.05 and P12.06 are PI adjustment parameters of the current loop. Increasing current loop KP or decreasing I
can enhance the dynamic features of system torque, but too strong regulation may cause device vibration, large
noise, overcurrent during acceleration and other problems upon shaft lock; decreasing KP or increasing I can enhance
the stability of the system.
Speed loop:
Increasing the proportional gain P can accelerate the dynamic response of the system; but too large P will cause
oscillation.
Decreasing the integral time I can accelerate the dynamic response of the system; but too small I will cause large
system overshoots and oscillation.
If the PI parameter is not well selected, the system may produce overvoltage failure (if there is no external braking
resistor or braking unit) after a fast start to high speed, which is due to the energy feedback produced in the
regenerative braking state of system during drop after the speed overshoot. This can be avoided by adjusting the PI
parameter.
