The functions take place when the contacts are closed.
1
Control signal (CS) 1 activates causing the out-
put frequency to rise. The motor runs forward.
8
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, however, has no effect on
the output frequency because the first selected
direction has the highest priority.
9
Run enable signal is set to TRUE, which causes
the frequency to rise towards the set frequency
because CS1 is still active.
3
CS1 is inactivated which causes the direction to
start changing (FWD to REV) because CS2 is
still active.
10
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
CS2 inactivates and the frequency fed to the
motor drops to 0.
11
The drive starts through pushing the Start button
on the keypad.
5
CS2 activates again causing the motor to accel-
erate (REV) towards the set frequency.
12
The keypad stop button is pushed again to stop
the drive.
6
CS2 inactivates and the frequency fed to the
motor drops to 0.
13
The attempt to start the drive through pushing
the Start button is not successful because CS1
is inactive.
7
CS1 activates and the motor accelerates (FWD)
towards the set frequency
