1 Control signal (CS) 1 actives causing the
output frequency to rise. The motor runs
forward because CS2 is inactive..
2 CS2 activates which causes the direction to
start changing (FWD to REV).
3 CS2 is inactivated which causes the
direction to start changing (REV to FWD)
because CS1 is still active.
4 Also CS1 inactivates and the frequency
drops to 0.
5 Despite the activation of CS2, the motor
does not start because CS1 is inactive.
6 CS1 activates causing the output
frequency to rise again. The motor runs
forward because CS2 is inactive.
Table 53.
Explanations:
7 Run enable signal is set to FALSE, which
drops the frequency to 0.The run enable
signal is configured with par. 5.7.
8 Before a successful start can take place, CS1
must be opened and closed again.
9 Keypad stop button is pressed and the
frequency fed to the motor drops to 0.(This
signal only works if Par.2.7 [Keypad stop
button] = 1)
10 Before a successful start can take place, CS1
must be opened and closed again.
11 CS1 inactivates and the frequency drops to 0.
