2-wire control: This is the input state (0 or 1) or edge (0 to 1 or 1 to 0), which controls running or stopping.
Example of “source” wiring:
LI1: forward
LIx: reverse
3-wire control (pulse control): A “forward” or “reverse” pulse is sufficient to command starting, a “stop” pulse is
sufficient to command stopping.
Example of “source” wiring:
LI1: stop
LI2: forward
LIx: reverse

: A change of state (transition or edge) is necessary to initiate operation, in order to prevent
accidental restarts after a break in the power supply.

[Fwd priority]
(PFO)

WARNING
UNINTENDED EQUIPMENT OPERATION
To change the assignment of
[2/3 wire control]
(tCC)
press the “ENT” key for 2 s.
It causes the following functions to return to factory setting:
[2 wire type]
(tCt)
and
[Reverse assign.]
(rrS)
below, and all functions which assign logic inputs and analog inputs.
The macro configuration selected will also be reset if it has been customized (loss of custom settings).
It is advisable to configure this parameter before configuring the
[1.6 COMMAND]

Check that this change is compatible with the wiring diagram used.
Failure to follow these instructions can result in death or serious injury.
