b5-01: PID Mode Setting
No.
(Hex.)
Name
Description
Default
(Range)
b5-01
(01A5)
PID Mode Setting
Sets the type of PID control.
0
(0 - 3)
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.
(Hex.)
Name
Description
Default
(Range)
b5-02
(01A6)
RUN
Proportional Gain (P)
Sets the proportional gain (P) that is applied to PID input.
2.00
(0.00 - 25.00)
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.
(Hex.)
Name
Description
Default
(Range)
b5-03
(01A7)
RUN
Integral Time (I)
Sets the integral time (I) that is applied to PID input.
0.5 s
(0.0 - 360.0 s)
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.
