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