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

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)

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.
