"Pole-changing reversing starter" control function
Description
This control function can be used to change the direction of rotation of a motor at both
speeds.
●
Start with "ON >" first activates the QE2 contactor control (RIGHT-SLOW)
●
Start with "ON >>" activates contactor control QE1 (CW-FAST)
●
Start with "ON <" activates contactor control QE4 (CCW-SLOW)
●
Start with "ON <<" activates contactor control QE5 (CCW-FAST)
●
with OFF deactivates the contactor controls.
The control commands can be issued to SIMOCODE pro from any control stations. Thus, the
inputs (plugs) must be connected to the corresponding sockets, preferably to the "Enabled
control command" sockets.
It does not matter in what order the control commands are given. Every fault message
causes the contactor control 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)
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."
The speed can be switched once the "Feedback ON" signal has expired (motor is switched
off)
on change-over from "FAST"→"SLOW" after the change-over pause has elapsed:
● Via the "OFF" control command
● Directly when "Saving change-over command" is activated.
SIMOCODE pro prevents the contactors for "FAST" and "SLOW" from being switched on
simultaneously. The "Change-over pause" can be used to delay switching from
"FAST"→"SLOW" to give the motor enough time to run down.
