This paramet er defines four di fferent control modes which controls the inverter operat ion through
external terminals.
0: Two-wire t ype control, integrat e Enabl e wit h di rection. Thi s mode is the most often used two-wire
control mode. The motor forwa rd and revers e ope rations are determi ned by the defined FWD and REV
t erminal command.

1: Two-wire c ontrol , s eparate Enable from direction. When this mode i s used, the defined F WD is enable
t erminal. The direction is determined by the defined REV state.

N ote: For two-wire operation mode, when F WD/RE V t erminal is enabled and th e stop comman d
produced by other sources stops t he equipment, the inverter does not start to operate after the s top
comman d disappears even if the con trol terminal FWD /REV is still valid. If the i nv erter needs to
operate, it is required to trigger FWD/RE V again.
