1. Control signal (CS) 1 activates and
causes the output frequency to increase.
The motor operates forward.
2. CS2 activates, but it does not have an
effect on the output frequency, because
the direction that is set first has the
highest priority.
3. CS1 becomes inactive and causes the
direction to start to change (FWD to
REV), because CS2 is still active.
4. CS2 becomes inactive and the frequency
that is fed to the motor goes to 0.
5. CS2 activates again and causes the
motor to accelerate (REV) to the set
frequency.
6. CS2 becomes inactive and the frequency
fed to the motor drops to 0.
7. CS1 activates and the motor accelerates
(FWD) to the set frequency

pushed, and the frequency that is fed to
the motor goes to 0. (This signal only
works if the value of P3.2.3 Keypad Stop
