PID Control
b5-01
PID Function Setting
PID Mode
This parameter determines the function of the PID control.
0: Disabled
1: D = Feedback
2: D = Feed-Forward

Intregral Time Setting
PID I Time
Sets the integral time for the PID controller. A setting of zero
disables integral control.

b5-04
Intregral Limit Setting
PID I Limit
Sets the maximum output possible from the integrator. Set as a
percentage (%) of maximum frequency.
0.0 to

b5-05
Derivative Time
PID D Time
Sets D control derivative time. A setting of 0.00 disables derivative
control.

b5-06
PID Output Limit
PID Limit
Sets the maximum output possible from the entire PID controller.
Set as a percentage (%) of maximum frequency.
0.00 to

100.0% A A A A
b5-07
PID Offset Adjustment
PID Offset
Sets the amount of offset of the output of the PID controller. Set as a
percentage (%) of maximum frequency.
The offset is summed with the PID output. This can be used to
artificially kick-start a slow starting PID loop.
–100.0 to
+100.0

PID Primary Delay Time
Constant
PID Delay Time
Sets the amount of time for the filter on the output of the PID
controller.

PID Output Level
Selection
Output Level Sel
Determines whether the PID controller will be direct or reverse
acting.
0: Normal Output
1: Reverse Output

PID Output Gain Setting
Output Gain
Sets the output gain of the PID controller.
0.0 to
25.0

b5-11
PID Output Reverse
Selection
Output Rev Sel
0: 0 limit (when PID output goes negative, Drive stops). 0 limit is
automatic when reverse prohibit is selected using b1-04.
1: Reverse (when PID goes negative, Drive reverses).

PID Feedback Loss
Detection Level
Fb los Det Lvl
Sets the PID feedback loss detection level as a percentage (%) of
maximum frequency (E1-04).
0 to 100 0% A A A A
b5-14
PID Feedback Loss
Detection Time
Fb los Det Time
Sets the PID feedback loss detection delay time in terms of
seconds.

b5-17
PID Accel/Decel Time
PID Acc/Dec Time
Applies an accel/decel time to the PID setpoint reference. The
Drive’s standard softstarter (C1-XX and S-curve) still affects the
output of the PID algorithm.

PID Setpoint Selection
PID Setpoint Sel
Allows the b5-19 setting to be the PID target setpoint value.

PID Setpoint Value
PID Setpoint
Sets the PID target value. Use only when b5-18 = 1
