P207
Proportional
Gain
5.0 0.0 {%} 100.0 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 and
must be used 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

Preset PID
Setpoint #4

P200 = 1 or 2
P240
Sleep Threshold 0.0 0.0 {Hz} 500.0 • If drive speed < P240 for longer
than P241, output frequency = 0.0
Hz; drive display =
SLP
• P240 = 0.0: Sleep mode is
disabled.
• P200 = 0…2: Drive will start again
when speed command is above
P240
• P242 > 0.0: Drive will restart when
the PID feedback differs from the
setpoint by more than the value
of P242 or when the PID loop
requires a speed above P240.
