●
Set one of digital inputs as '35: Forward running (FWD)'
●
Set one of digital inputs as '36: Reverse running (REV)'
●
Set one of digital inputs as '25: 3-wire control'
To use 3-wire function, define the digital inputs first, and then activate the con-
trol mode. Otherwise, warning code 'PrSE' will be displayed on the operating

code 'PrSE' will be displayed.
Step 2: Activate 3-wire control 1
Set [E1.15] = '2: 3-wire control 1'.
Example:
Connected switch K1 to X1, and set [E1.00] = '35: Forward running (FWD)',
edge-sensitive.
Connected switch K2 to X2, and set [E1.01] = '36: Reverse running (REV)', level-
