CS1:Start
CS2:Reverse
Explanations:
1 Control signal (CS) 1 actives causing the
output 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 configured with par. 5.7.
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
frequency fed to the motor drops to
0.(This signal only works if Par.2.7 [Key-
pad stop button] = 1)
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 activates 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 fre-
quency 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 success-
ful because CS1 is inactive.
