| Pump control |
An inverter controls multiple driving pumps at a time combining with driving sources of the inverter and commercial power. The inverter’s integrated PID controller controls them in the flowrate, pressure and so on. The inverter controls each member of pump control sequences issuing the power source switching signal between the inverter output and commercial power. Two control modes are available. One is a fixed motor-driving mode where the inverter exclusively controls the single pump. Another is a cyclic motor-driving mode where the inverter cyclically controls a member of pumps.
- Fixed motor-driving mode :
Pumps under control = one inverter driven + four commercial power driven
- Cyclic motor-driving mode :
Pumps under control = three inverter /commercial power driven (In this mode, a relay output card option (OPC-F1S-RY) is required.)
Furthermore, this control features a periodic switching function, an average time drive-switching function, a cumulative pump run time monitor, a cumulative relay activating times monitor and so on. |
