6 The start attempt with CS1 is not successful, be-
cause the Run enable signal is still OPEN.
7 CS1 activates and the motor accelerates (FWD) to
the set frequency, because the Run enable signal
was set to CLOSED.
8 The STOP button on the keypad is pushed, and the
frequency that is fed to the motor goes to 0. (This
signal only works if the value of P2.4.3 Keypad Stop
Button is Yes.)
9 CS3 activates and causes the motor to start and to
operate in the reverse direction.
10 CS2 becomes inactive and causes the frequency to
go to 0.
