(Hex.)
b5-01 PID Mode Setting
(01A5)
0 : Disabled
1 : Standard
The drive does D control on the difference between the feedback value and the PID setpoint output through U5-02
[PID Input].
3 : Fref + PID Trim
The drive adds the frequency reference to the PID output. The drive does D control on the difference between the
feedback value and the PID setpoint output through U5-02.
Note:
• When you set b5-01 = 1 or 3 from the keypad, the drive will automatically set H3-10 = B [Terminal A2 Function Selection = PID
Feedback] and o1-26 = 501 [Custom Monitor 3 = PID Feedback]. The drive will also update the defaults for H3-10 and o1-26 when you
change b5-01.
• When you set b5-01 = 0 from the keypad, the drive will automatically set H3-10 = 0 [Frequency Reference] and o1-26 = 103 [Output
Current].
• When you set b5-01 from a different method, for example MEMOBUS, the drive will automatically update the defaults for H3-10 and o1-
26, but it will not update the parameters.

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 faster. If the integral time is too short, it can cause overshoot or
oscillation.
Set b5-03 = 0.0 to disable I control.
