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.)

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)
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.
0
(0, 1)
This parameter is disabled when b5-01 = 3, 4 [PID Mode Setting = Fref + PID Trim, Fref + PID Trim (D on
feedback)] . There is no limit for PID output (PID output can be positive or negative). Operates the same as setting
“
1: Enabled: Negative lower limit
”
.
0 : Lower Limit is Zero
When PID output is negative, PID output is limited to 0 and drive output is shut off.
1 : Negative Output Accepted
When the PID output is negative, the motor will rotate in reverse. When b1-04 = 1 [Reverse Operation Selection
= Reverse Disabled] , the lower limit is 0.
