This parameter determines the limit of the PID Command frequency. If this parameter
is set to 120%, then the maximum output frequency while in the PID operation will be
(120% x Pr.01-00) 72%.

PI Control: controlled by the P action only, and thus, the deviation cannot be eliminated
entirely. To eliminate residual deviations, the P + I control will generally be utilized.
And when the PI control is utilized, it could eliminate the deviation incurred by the
targeted value changes and the constant external interferences. However, if the I
action is excessively powerful, it will delay the responding toward the swift variation.
The P action could be used solely on the loading system that possesses the integral
components.
