b5-01: PID Function Setting
Enables or disables the PID operation and selects the PID operation mode.
No.

Default
b5-01
PID Function Setting
0 to 4
0
Setting 0: PID disabled
Setting 1: Output Frequency = PID Output 1
The PID controller is enabled and the PID output builds the frequency reference. The PID input is D controlled.
Setting 2: Output Frequency = PID Output 2
The PID controller is enabled and the PID output builds the frequency reference. The PID feedback is D controlled.
Setting 3: Output Frequency = Frequency Ref PID Output 1
The PID controller is enabled and the PID output is added to the frequency reference. The PID input is D controlled.
Setting 4: Output Frequency = Frequency Ref PID Output 2
The PID controller is enabled and the PID output is added to the frequency reference. The PID feedback is D controlled.
n
b5-02: Proportional Gain Setting (P)
Sets the P gain that is applied to the PID input. A large value will tend to reduce the error, but may cause instability
(oscillations) if too high. A small value may allow too much offset between the setpoint and feedback.

n
b5-03: Integral Time Setting (I)
Sets the time constant that is used to calculate the integral of the PID input. The smaller the integral time set to b5-03, the
faster the offset will be eliminated. If set too short, it can cause overshoot or oscillations. To turn off the integral time, set
b5-03 = 0.00.

b5-04: Integral Limit Setting
Sets the maximum output possible from the integral block. Set as a percentage of the maximum frequency (E1-04).

b5-04
Integral Limit Setting
0.0 to 100.0
100.0
Note:
On some applications, especially those with rapidly varying loads, the output of the PID function may show a fair amount of oscillation.
To suppress this oscillation, a limit can be applied to the integral output by programming b5-04.
n
b5-05: Derivative Time (D)
Sets the time the drive predicts the PID input/PID feedback signal based on the derivative of the PID input/PID feedback.
Longer time settings will improve the response but can cause vibrations. Shorter settings will reduce the overshoot but
also reduce the controller responsiveness. D control is disabled by setting b5-05 to zero seconds.
