Soft Starter With Reversing Contactor" Control Function - Siemens SIMOCODE pro Operating Manual

4.2.2.16

"Soft starter with reversing contactor" control function

Description
With this control function, SIMOCODE pro can activate the 3RW soft starter including an
additional reversing contactor. Thus, the 3RW soft starters are connected via
SIMOCODE pro to the bus. SIMOCODE pro can also control the direction of rotation of the
motor (forwards and backwards).
Control commands
● Start with "ON >" activates contactor controls QE1 and QE4 (clockwise, i.e. forwards)
● Start with "ON <" activates contactor controls QE2 and QE4 (counterclockwise, i.e.
reverse).
● Stop with "OFF" first deactivates contactor control QE4. When the "Feedback ON" signal
is no longer issued, contactor control QE1 / QE2 is deactivated 3 s later to leave enough
time for a soft 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 controls to be deactivated.
Switching the direction of rotation
The direction of rotation can be switched once the "Status - ON >" or "Status - ON <" signal
has expired (motor is switched off) AND the interlocking time has elapsed:
● Via the "OFF" control command
● Directly when "Saving change-over command" is activated.
SIMOCODE pro prevents both contactors from switching on at the same time. Switching
from one direction of rotation to the other can be delayed via the interlocking time.
