13.3 3-WIRE COMMAND [33]

The group defined as "3-Wire Command" refers to the function Run/Stop programmed via digital inputs.
With this function it is possible to activate or deactivate the motor by means of pulses at the digital inputs
configured as Run (DIx = 6) and Stop (DIx = 7). It is important to notice that the Stop pulse is inverted, i.e., a
transition from +24 V to 0 V.
For a better understanding of this function it is recommended to verify the

13.4 FORWARD RUN/REVERSE RUN COMMANDS [34]

The FWD Run/REV Run function can be used to command the motor in the forward direction and in the reverse
direction by means of digital inputs.
13
With the application of +24 V to the input programmed for FWD Run (DIx = 4), the motor accelerates in the
forward direction until reaching the speed reference. Once the FWD Run input has been released (0 V) and +24
V has been applied at the input programmed for REV Run (DIx = 5), the CFW-11 will activate the motor in the
reverse direction until it reaches the speed reference. Refer to the
