Digital and Analog Inputs and Outputs
d) FORWARD/REVERSE
This command is the combination of two DIS: one programmed for forward run and the other for reverse run.
e) START / STOP
This function tries to reproduce the activation of a three-wire direct start with retention contact, where a pulse in
the DIx-Start enables the motor spin while the Dlx-Stop is active.
NOTE!
All the digital inputs set for General Enable, Fast Stop, Forward Run/Reverse Run and Start/Stop
must be in the "Active" state so that the inverter can enable the motor spin.
