■
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
Increase the time setting to increase controller responsiveness and possibly cause vibrations. Decrease the time
setting to decrease overshoot and decrease controller responsiveness.
Set b5-05 = 0.00 to disable D control.

V/f CL-V/f OLV CLV AOLV
Sets the proportional gain (P) that is applied to PID input.
V/f CL-V/f OLV CLV AOLV
Sets the integral time (I) that is applied to PID input.
Figure 11.40 Integral Time and Deviation
V/f CL-V/f OLV CLV AOLV
Sets the upper limit for I control as a percentage of E1-04 [Maximum
Output Frequency].
V/f CL-V/f OLV CLV AOLV
Sets the derivative time (D) for PID control. This parameter adjusts system
responsiveness.
