PID I Limit
Sets the maximum output possible from the integrator as a
percentage of the maximum output frequency.
The function of b5-04 is disabled when P1-24 > 0

(01AA) PID Output Limit
PID Limit
Sets the maximum output possible from the entire PID controller
as a percentage of the maximum output frequency.
Default: 100.0%
Min.: 0.0
Max.: 100.0

Min.: -100.0
Max.: 100.0
–
b5-08
(01AC) PID Primary Delay
Time Constant
PID Delay Time
Sets a low pass filter time constant on the output of the PID
controller.
Default: 0.00 s
Min.: 0.00
Max.: 10.00

(01AE) PID Output Gain Setting Output Gain
Sets the gain applied to the PID output.
Note:
Parameter setting cannot be changed when the
drive is operating the motor in models 4A0930
and 4A1200.
Default: 1.00
Min.: 0.00
Max.: 25.00

PID Output Reverse
Selection
Output Rev Sel
0: 0 limit
1: Reverse
0: Negative PID output triggers zero limit.
1: Rotation direction reverses with negative PID output.
Note:
When using setting 1, make sure reverse
operation is permitted by b1-04.
Default: 0
Range: 0, 1

b5-12
(01B0)
Feedback Loss 4 to 20
mA Detection Selection
Fdbk 4-20mA Det
0: Disabled
1: Alarm only
2: Fault
3: Run At b5-13
Performs a 4 to 20 mA wire break detection on the analog input
that is programmed for PID feedback.
0: Disabled
1: Alarm only
2: Fault
3: Run at b5-13
Default: 2
Range: 0 to 3
–
b5-13
(01B1)
Feedback Loss Goto
Frequency
FdbkLossGotoFreq
Sets the speed at which the drive will run if a 4 to 20 mA wire
break is detected on the PID Feedback and when b5-12 is set to
3 (Run at b5-13).
Default: 0.0 Hz
Min.: 0.0
Max.: 400.0
–
b5-14
(01B2) Feedback Loss of Prime
Level
FdbkLoss LOP Lvl
Detects loss of prime in the pump when a wire break condition
has occurred.
When the measured quantity determined by P1-18 (output
current, kilowatts, or power) drops below this level for the time
set in P1-20 and the output frequency is at the level set in b5-13,
a “Loss of Prime” condition occurs.
The drive responds to the “Loss of Prime” condition depending
on the setting of P1-22, Loss of Prime Selection.
Default: 0.0 A
<1>
Min.: 0.0
Max.: 1000.0

b5-15
(01B3)
<2>
Feedback Loss Go To
Frequency Time Out
FdbkLossGotoTimO
When b5-12 = 3 and the Feedback signal is lost, the drive will
run at the b5-13 speed for the b5-15 time, after which the drive
will fault on Feedback Loss (FDBKL).
Timeout is disabled when set to 0sec and the drive will run
indefinitely at b5-13.
Default: 0 s
Min.: 0
Max.: 6000
–
b5-16
(01B3)
<2>
Feedback Loss Start
Delay
FdbkLossStartDly
When an AUTO Run command is initiated, the drive will not
fault on Feedback Loss (FDBKL) or use the Feedback Loss
GoTo Frequency (b5-13) until the b5-16 time has expired.
Default: 0.0 s
Min.: 0.0
Max.: 120.0
–
b5-17
(01B5) PID Accel/Decel Time PID Acc/Dec Time
Sets the acceleration and deceleration time to PID setpoint.
Default: 0.0 s
Min.: 0.0
Max.: 6000.0
–
b5-32
(01EE)
<2>
Integrator Ramp Limit
IntegratrRampLim
When set to a value greater than zero, the PI Integrator is forced
to be within +/- this amount of the soft starter output.
Default: 0.0 Hz
Min.: 0.0
Max.: 10.0
