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
8. The Run enable signal is set to FALSE,
which causes the frequency to go to 0.
Configure the Run enable signal with
parameter P3.5.1.15.
9. The Run enable signal is set to TRUE,
which causes the frequency to increase
to the set frequency, because CS1 is still
active.
10. The STOP button on the keypad is
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
Button is Yes.)
11. The drive starts because the START
button on the keypad was pushed.
12. The STOP button on the keypad is
pushed again to stop the drive.
13. The attempt to start the drive with the
START button is not successful, because
CS1 is inactive.
