Figure 9.5: Start/Stop logic, selection 2
Explanations:
1 Control signal (CS) 1 actives causing the
output frequency to rise. The motor runs
forward.
2 CS2 activates which, however, has no
effect on the output frequency because
the first selected direction has the high-
est priority.
3 CS1 is inactivated which causes the
direction to start changing (FWD to REV)
because CS2 is still active.
4 CS2 inactivates and the frequency fed to
the motor drops to 0.
5 CS2 activates again causing the motor to
accelerate (REV) towards the set fre-
quency.
6 CS2 inactivates and the frequency fed to
the motor drops to 0.
