2-wire control mode 2 (Forward / reverse, run / stop)
Step 1: Activate 2-wire control mode 2
Set [E1.15] = '1: Forward / reverse, run / stop'.
Step 2: Define two digital inputs
●
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)'.
