PID Function
Setting This parameter determines the
function of the PID control.
0: Disabled
1: D= Feedback
2: D= Feed-Forward
3: Freq. Ref. + PID output
(D = Feedback)
4: Freq. Ref. + PID output
(D = Feed-Forward)
0 to 4 0 No A A A A A
PID Mode
b5-02
Proportional
Gain Setting
Sets the proportional gain of the
PID controller.
0.00
to
25.00
1.00 Yes A A A A A
PID Gain
b5-03
Intregral Time
Setting
Sets the integral time for the PID
controller. A setting of zero
disables integral control. 0.0
to
360.0
1.0sec Yes A A A A A
PID I Time
b5-04
Intregral Limit
Setting Sets the maximum output possible
from the integrator. Set as a
percentage (%) of maximum
frequency.
0.0
to
100.0
100.0% Yes A A A A A
PID I Limit
b5-05
Derivative
Time
Sets D control derivative time. A
setting of 0.00 disables derivative
control. 0.00
to
10.00
0.00sec Yes A A A A A
PID D Time
b5-06
PID Output
Limit Sets the maximum output possible
from the entire PID controller. Set
as a percentage (%) of maximum
frequency.
0.0
to
100.0
100.0% Yes A A A A A
PID Limit
b5-07
PID Offset
Adjustment 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
0.0% Yes A A A A A
PID Offset
b5-08
PID Primary
Delay Time
Constant Sets the amount of time for the
filter on the output of the PID
controller.
Note: The offset is summed with
the PID output. This can be used
to artifically kick-start a slow
starting PID loop.
Note: Normally , change is not
required.

b5-09
PID Output
Level Selection Determines whether the PID
controller will be direct or
reverse acting.
0: Normal Output (direct acting)
1: Reverse Output (reverse
acting)
0 to 1 0 No A A A A A
