"Reversing starter" control function

Description
With this control function, SIMOCODE pro can control the direction of rotation of the motor
(forwards and backwards).
Control commands
● Start with "ON >" activates the QE1 contactor control (clockwise, i.e. forwards)
● Start with "ON <" activates the QE2 contactor control (counterclockwise, i.e. reverse)
● Stop with "OFF" deactivates internal contactor controls QE1 and QE2.
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 contactor controls QE1 and QE2 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. Changing
from one direction of rotation to the other can be delayed via the interlocking time.
