Table 22: Legend to IO A Start/Stop logic = 1.
1
Control signal (CS) 1 activates 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 KeypadStopButton
[P3.2.3] = Yes)
3
CS1 activates causing the output frequency
to rise again. The motor runs forward.
8
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 Run Enable
(P3.5.1.10).
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.
