2-wire control mode 1
Step 1: Activate 2-wire control mode 1
Set [E1.15] = '0: 2-wire forward / stop, reverse / stop'.

● Set one of digital inputs as '35: Forward running (FWD)'
● Set one of digital inputs as '36: Reverse running (REV)'
Example:
Connected switch K1 to X1, and set [E1.00] = '35: Forward running (FWD)'.
Connected switch K2 to X2, and set [E1.01] = '36: Reverse running (REV)'.
