This parameter defines five different modes of controlling the operation of the inverter via the external
terminals
1: Two-line mode 1: This mode is the most commonly used two-line mode. The forward / reverse
rotation of the motor is decided by the commands of Dix, DIy terminals; when Dix and DIy are
effective, the inverter to keep the first effective terminal determined direction. The terminal function
set as below:
