For instance: To disable Fault ILP only needs to set Bit 6 corresponding to ILP as 1, i.e.
FC-28=01000000.
To disable Fault OLP and EST only needs to set Bit 1 corresponding to OLP and Bit 6
corresponding to EST as 1, i.e. FC-29=01000010.
1. Unless special needs, please do not disable any protection function in order to
avoid that inverter is damaged if there is not fault protection when the faults occurs.
2. OL1 is motor overload. Fault display is also as OL. Generally, motor overload is
longer than inverter overload, so that the relative settings do not need to be changed.
