b5-05: Derivative Time (D)
No.
(Hex.)
Name
Description
Default
(Range)
b5-05
(01A9)
RUN
Derivative Time (D)
Sets the derivative time (D) for PID control. This parameter adjusts system responsiveness.
0.00 s
(0.00 - 10.00 s)
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.
(Hex.)
Name
Description
Default
(Range)
b5-06
(01AA)
RUN
PID Output Limit
Sets the maximum possible output from the PID controller as a percentage of the Maximum Output
Frequency.
100.0%
(0.0 - 100.0%)
■
b5-07: PID Offset Adjustment
No.
(Hex.)
Name
Description
Default
(Range)
b5-07
(01AB)
RUN
PID Offset Adjustment
Sets the offset for the PID control output as a percentage of the Maximum Output Frequency.
0.0%
(-100.0 - +100.0%)

b5-08: PID Primary Delay Time Constant
No.
(Hex.)
Name
Description
Default
(Range)
b5-08
(01AC)
RUN
Expert
PID Primary Delay Time
Constant
Sets the primary delay time constant for the PID control output. Usually it is not necessary to change
this setting.
0.00 s
(0.00 - 10.00 s)
Prevents resonance if there is a large quantity of mechanical friction or if rigidity is unsatisfactory. Set the value larger
than the resonant frequency cycle. A value that is too large will decrease drive responsiveness.
■
b5-09: PID Output Level Selection
No.
(Hex.)
Name
Description
Default
(Range)
b5-09
(01AD)
PID Output Level Selection
Sets the polarity of the PID output.
0
(0, 1)
Use this parameter in applications that decrease the drive output frequency when you increase the PID setpoint.
0 : Normal Output (Direct Acting)
A positive PID input increases the PID output (direct acting).
1 : Reverse Output (Reverse Acting)
A positive PID input decreases the PID output (reverse acting).
■
b5-10: PID Output Gain Setting
No.
(Hex.)
Name
Description
Default
(Range)
b5-10
(01AE)
RUN
PID Output Gain Setting
Sets the amount of gain to apply to the PID output.
1.00
(0.00 - 25.00)
