This parameter defines four different contr ol modes which controls the inverter operation through
5/14/201e8xternal terminals.
0: Two-wiretype control, integrate Enable with direction. This mode is the most oft en used two-wire
control mode. The motor forward and reverse operations a re determined by the defined FWD and REV
terminal command.

EN is defining the corresponding terminal function as Function 3 “Three-wire operation control”.
Note: For two-wire operation mode, when FWD/REV terminal is enabled and the stop command
produced by other sources stops the equipment, the inverter does not st art to operate after the stop
command disappears even if the control terminal FWD/REV is still valid. If the inver ter needs to
operate, it is required to trigger FWD/REV again.
