Fb Control Optimization Parameters; E0 Solar Water Pump Special Group - Powtran PI500-S Series Manual

F9.05 = 1: Select the standard Modbus protocol，F9.05 = 0: When reading a command, the
slave returns more bytes than the standard Modbus protocol.

5-1-11.Fb Control optimization parameters

Code Parameter name
Fb.00 Fast current limiting manner
Enable Quick Current Limiting function, which can minimize the overcurrent fault of
inverter , and ensure the uninterrupted operation of inverter. If the drive is in the state of fast
current limiting for a long period of time , the inverter may be damaged by overheating and others,
this case is not allowed, so the inverter will alarm fault with fault ID Err.40, it indicates that the
inverter exists overload and needs to be shut down.
Fb.01 Undervoltage point setting
Used to set the voltage value of inverter undervoltage fault with fault ID Err.09 , the different
voltage levels of inverter 100.0% corresponds to the different voltage points are as follows:
Single-phase 220V or three-phase 220V: 200V three-phase 380V: 350V.
Fb.02 Overvoltage point setting
Single-phase 220V or three-phase 220V: 200V three-phase 380V: 350V.
