Figure 44. I/O A Start logic = 0
Explanations:
Table 136.
1
Control signal (CS) 1 activates causing the output
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 configured
with parameter P3.5.1.15.
2
CS2 activates which, however, has no effect on the
output frequency because the first selected direc-
tion 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 frequency
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 accelerate
(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 inac-
tive.
7
CS1 activates and the motor accelerates (FWD)
towards the set frequency
