1 Control signal (CS) 1 actives causing the
output frequency to rise. The motor runs
forward.
2 CS2 inactivates causing the frequency to
drop to 0.
3 CS1 activates causing the output
frequency to rise again. The motor runs
forward.
4 Run enable signal is set to FALSE, which
drops the frequency to 0. The run enable
signal is configured with par. 5.7.
5 Start attempt with CS1 is not successful
because Run enable signal is still FALSE.
Table 47.
Explanations
6 CS1 activates and the motor accelerates
(FWD) towards the set frequency because the
Run enable signal has been set to TRUE.
7 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)
8 CS1 activates causing the output frequency
to rise again. The motor runs forward.
9 CS2 inactivates causing the frequency to
drop to 0.
