◆ P9-12 Remove Pump Mode
◆ P9-13 Remove Freq Level
Setting Range: 0.0 ~ 120.0 Hz
Factory Default: 40.0 Hz
Refer to parameter P9-23 in Appendix A for description details.
◆ P9-14 Remove Delta Level
Setting Range: 0 ~ 6000.0
Factory Default: 0.0
Refer to parameter P9-24 in Appendix A for description details.
◆ P9-15 Remove Delay Time
Setting Range: 0 ~ 3600 s
Factory Default: 10 s
Refer to parameter P9-15 in Appendix A for description details.
◆ P9-16 Stabilization Time
Setting Range: 0 ~ 3600 s
Factory Default: 3 s
If Stabilize Time P9-16 > 0, then whenever a pump becomes a lag drive, or gets de-staged that disables lead-lag control and pump
protection. It will resume these functions when the timer P9-16 expires, which counts only when the drive becomes a lead drive once
again.
◆ P9-17 Setpoint Modifier
Setting Range: -6000.0 ~ 6000.0
Factory Default: 0.0
Setpoint Modifier P9-17 is used to increase or decrease the setpoint each time an additional pump is brought online to compensate for
system losses or gains. The drive's setpoint is modified using this calculation:
Pump X: Setpoint + ((X-1)(P9-17))
Thus, if there is only one pump running, the setpoint is not modified.
◆ P9-18 High Feedback Quick De-Stage
Setting Range: 0.0 ~ 100.0%
Factory Default: 90.0%
Refer to parameter P9-18 in Appendix A for description details.
