b5-02: Proportional Gain (P)
No.
Name
(Hex.)
b5-02 Proportional Gain (P)
(01A6)
RUN
Larger values decrease errors, but can cause oscillations. Smaller values let too much offset between the setpoint
and feedback.
Set b5-02 = 0.00 to disable P control.
■
b5-03: Integral Time (I)
No.
Name
(Hex.)
b5-03 Integral Time (I)
(01A7)
RUN
Set a short integral time in b5-03 to remove the offset more quickly. If the integral time is too short, overshoot or
oscillation can occur.
Set b5-03 = 0.00 to disable I control.
■
b5-04: Integral Limit
No.
Name
(Hex.)
b5-04 Integral Limit
(01A8)
RUN
Applications with loads that quickly change will cause the output of the PID function to oscillate. Set this
parameter to a low value to prevent oscillation, mechanical loss, and motor speed loss.
■
b5-05: Derivative Time (D)
No.
Name
(Hex.)
b5-05 Derivative Time (D)
(01A9)
RUN
When you increase the time setting, it will increase controller responsiveness, but it can also cause vibration.
When you decrease the time setting, it will suppress overshoot and decrease controller responsiveness.
Set b5-05 = 0.00 to disable D control.
■
b5-06: PID Output Limit
No.

b5-06 PID Output Limit

V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the upper limit for integral control (I) as a percentage of the Maximum Output Frequency.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the derivative time (D) for PID control. This parameter adjusts system responsiveness.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the maximum possible output from the PID controller as a percentage of the Maximum
Output Frequency.
