Check that the modification of the 2 wire type control is compatible with the wiring diagram used.

2-wire type control parameter can only be accessed if

v

Level: State 0 or 1 is taken into account for run or stop.

v

Transition: A change of state (transition or edge) is necessary to initiate operation, to help prevent 
accidental restarts after a power supply interruption.

v

Priority FW: State 0 or 1 is taken into account for run or stop, but the "forward" input takes priority over 
the "reverse" input.

v

Positive: the inputs are active (state 1) at a voltage equal to or higher than 11 V (for example +24 V 
terminal). They are inactive (state 0) when the drive is disconnected or at a voltage lower than 5 V.

v

Negative using internal supply: the inputs are active (state 1) at a voltage lower than 10 V (for example 
COM terminal). They are inactive (state 0) at a voltage equal to or higher than 16 V or when the drive is 
disconnected.

v

Negative using external supply : the inputs are active (state 1) at a voltage lower than 10 V (for example 
COM terminal). They are inactive (state 0) at a voltage equal to or higher than 16 V.

Note: The modification will be taken into account only at the next control power on.
