CS1: Start
CS2: Reverse
Explanations:
1
Control signal (CS) 1 activates causing the out-
put frequency to rise. The motor runs forward.
7
Run enable signal is set to FALSE, which drops
the frequency to 0. The run enable signal is con-
figured with parameter P3.5.1.10.
2
CS2 activates which causes the direction to start
changing (FWD to REV).
8
Run enable signal is set to TRUE, which causes
the frequency to rise towards the set frequency
because CS1 is still active.
3
CS2 is inactivated which causes the direction to
start changing (REV to FWD) because CS1 is
still active.
9
Keypad stop button is pressed and the fre-
quency fed to the motor drops to 0. (This signal
only works if P3.2.3 Keypad stop button = Yes)
4
Also CS1 inactivates and the frequency drops to
0.
10
The drive starts through pushing the Start button
on the keypad.
5
Despite the activation of CS2, the motor does
not start because CS1 is inactive.
11
The drive is stopped again with the stop button
on the keypad.
6
CS1 activates causing the output frequency to
rise again. The motor runs forward because CS2
is inactive.
12
The attempt to start the drive through pushing
the Start button is not successful because CS1
is inactive.
