"Soft starter" control function

Description
With this control function, SIMOCODE pro can activate the 3RW soft starter. Thus, the
3RW soft starters are connected via SIMOCODE pro to the bus.
Control commands
● Start with "ON >" activates contactor controls QE1 and QE4.
● Stop with "OFF" first deactivates contactor control QE4. When the signal "Feedback ON"
has expired, the QE1 contactor control is deactivated 3 s later in order to facilitate a
smooth run down via the soft starter.
● With "Reset", the QE3 contactor control is activated for 20 ms and sends the soft starter
an acknowledgement signal via a parameterizable relay output.
The control commands can be issued to SIMOCODE pro from any control stations (see also
the description of "control stations"). Thus, the inputs (plugs) must be connected to the
corresponding sockets, preferably to the "Enabled control command" sockets.
Every fault message causes the contactor control to be deactivated.
Making internal assignments
You have to make the following assignments:
1. Assign the QE1 contactor control to the relay output which controls the coil of the line
contactor.
2. Assign contactor control QE4 to any relay output from which the "ON input" of the soft
starter is to be controlled.
3. Assign the QE3 contactor control to the relay output that supplies the 20 ms
acknowledgment signal to the soft starter.
4. Assign the "ON >" and "OFF" control commands to the enabled control commands.
5. Assign the SIMOCODE pro input to which the "Fault" signal output of the soft starter is
connected to the input (socket) of the standard function "External fault 1."
6. The "startup end" signal of the soft starter can also be wired to one of the inputs and
processed by SIMOCODE pro.
Note
In order to avoid disconnections due to faults, the "Execution time" parameter in
SIMOCODE pro must be set at least to the soft run-down time of the soft starter.
Note
If the SIMOCODE pro S basic unit is used, an additional multifunction module is required
for this control function.
