4.5.4 PID Parameters
Code Possible Settings
IMPORTANT
No. Name Default Selection
P200
PID Mode 0 0 Disabled • Normal-acting: As feedback increases,
motor speed decreases
• Reverse-acting: As feedback increases,
motor speed increases
• PID mode is disabled in Vector Torque mode
(P300 = 5)
• Selections 3, 4: If P112=1, PID controller
output sets the speed, (range -max freq
to +max freq)
1 Normal-acting
2 Reverse-acting
3 Normal-acting, Bi-directional
4 Reverse-acting, Bi-directional
NOTE
To activate PID mode, one of the TB-13 inputs (P121...P124) must be used to select
the Auto Reference that matches the desired PID setpoint reference. If the selected
PID setpoint reference uses the same analog signal as the PID feedback (P201), an
F.IL fault will occur.
Example: The desired PID setpoint reference is the keypad (
p
and
q
). Set TB-13x = 6
(Auto Reference: Keypad):
• TB-13x = closed: PID mode is active
• TB-13x = open: PID mode is disabled and the drive speed will be controlled by the
reference selected in P101.

p204
Feedback at
Minimum Signal 0.0 -99.9 3100.0 Set to match the range of the feedback signal
being used
Example: Feedback signal is 0 - 300 PSI; P204
= 0.0, P205 = 300.0
p205
Feedback at
Maximum Signal 100.0 -99.9 3100.0
p207
Proportional Gain 5.0 0.0 {%} 1000.0 Used to tune the PID loop:
• Increase P207 until system becomes
unstable, then decrease P207 by 10-15%
• Next, increase P208 until feedback matches
setpoint
• If required, increase P209 to compensate for
sudden changes in feedback
p208
Integral Gain 0.0 0.0 {s} 20.0
p209
Derivative Gain 0.0 0.0 {s} 20.0
NOTE
• Derivative Gain is very sensitive to noise on the feedback signal. Use with care.
• Derivative Gain is not normally required in pump and fan applications
p210
PID Setpoint Ramp 20.0 0.0 {s} 100.0 • time of setpoint change from P204 to P205
or vice versa.
• Used to smooth the transition from one PID
setpoint to another, such as when using the
Preset PID Setpoints (P231...P233)

Minimum Alarm 0.0 P204 P205 Use with P140, P142 = 18...23
