■ 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 E1-04 [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 E1-04
[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)
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)
Applies a gain to the PID output and can help when b5-01 = 3 or 4 [PID Mode Setting = Fref + PID Trim, Fref +
PID Trim (D on feedback)].
■ b5-11: PID Output Reverse Selection
No.
(Hex.)
Name Description
Default
(Range)
b5-11
(01AF)
PID Output Reverse
Selection
Sets the function that enables and disables reverse motor rotation for
negative PID control output.
