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

Integral Gain 0.0 0.0 {s} 20.0

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

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

Maximum Alarm 0.0 P204 P205

Preset PID Setpoint #1 0.0 P204 P205 TB-13A activated; P121 = 3 and P200 = 1 or 2

Preset PID Setpoint #2 0.0 P204 P205 TB-13B activated; P122 = 3 and P200 = 1 or 2

Preset PID Setpoint #3 0.0 P204 P205 TB-13C activated; P123 = 3 and P200 = 1 or 2

Preset PID Setpoint #4 0.0 P204 P205 TB-13D activated; P124 = 3 and P200 = 1 or 2

Sleep Threshold 0.0 0.0 {Hz} 500.0 • If drive speed < P240 for longer than P241,

output frequency = 0.0 Hz; drive display =

• 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.
