1 CS1: Forward (edge)
CS2: Inverted stop
1 Control signal (CS) 1 activates 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 Run Enable
(P3.5.1.10).
5 Start attempt with CS1 is not successful
because Run enable signal is still FALSE.

signal only works if KeypadStopButton
[P3.2.3] = Yes)
8 CS1 activates causing the output frequency
