8.1.3 Group 3.2: Start/Stop setup
Start/Stop commands are given differently depending
on the control place.
Remote control place (I/O A): Start, stop and
reverse commands are controlled by 2 digital inputs
chosen with parameters P3.5.1.1 and P3.5.1.2. The
functionality/logic for these inputs is then selected
with parameter P3.2.6 (in this group).
Remote control place (I/O B): Start, stop and
reverse commands are controlled by 2 digital inputs
chosen with parameters P3.5.1.4 and P3.5.1.5. The
functionality/logic for these inputs is then selected
with parameter P3.2.7 (in this group).
Local control place (Keypad): Start and stop
commands come from the keypad buttons, while the
direction of rotation is selected by the parameter
P3.3.1.9.
Remote control place (Fieldbus): Start, stop and
