1. Control signal (CS) 1 activates and
causes the output frequency to increase.
The motor operates forward.
2. CS2 becomes inactive and causes the
frequency to go to 0.
3. CS1 activates and causes the output
frequency to increase again. The motor
operates forward.
4. CS3 activates and causes the direction to
start to change (FWD to REV).
5. The Run enable signal is set to FALSE,
which causes the frequency to go to 0.
Configure the Run enable signal with
parameter 3.5.1.15.
6. The start attempt with CS1 is not
successful, because the Run enable
signal is still FALSE.
7. CS1 activates and the motor accelerates
(FWD) to the set frequency, because the
Run enable signal was set to TRUE.
8. 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.)
9. CS3 activates and causes the motor to
start and to operate in the reverse
direction.
10. CS2 becomes inactive and causes the
frequency to go to 0.
