1 Control signal (CS) 1 activates and causes the output
frequency to increase. The motor operates forward
because CS2 is inactive.
2 CS2 activates, which causes the direction to start to
change (FWD to REV).
3 CS2 becomes inactive, which causes the direction to
start to change (REV to FWD), because CS1 is still ac-
tive.
4 CS1 becomes inactive and the frequency goes to 0.
5 CS2 activates, but the motor does not start because
CS1 is inactive.
6 CS1 activates and causes the output frequency to in-
crease again. The motor operates forward, because
CS2 is inactive.
