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)
p214 Minimum Alarm 0.0 P204 P205 Use with P140, P142 = 18...23
P215 Maximum Alarm 0.0 P204 P205
P231 Preset PID Setpoint #1 0.0 P204 P205 TB-13A activated; P121 = 3 and P200 = 1 or 2
P232 Preset PID Setpoint #2 0.0 P204 P205 TB-13B activated; P122 = 3 and P200 = 1 or 2
P233 Preset PID Setpoint #3 0.0 P204 P205 TB-13C activated; P123 = 3 and P200 = 1 or 2
P234 (2) Preset PID Setpoint #4 0.0 P204 P205 TB-13D activated; P124 = 3 and 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.
