1
Control signal (CS) 1 activates and causes the output
frequency to increase. The motor operates forward.
2
CS2 becomes inactive and causes the frequency to
go to 0.
3
CS1 activates and causes the output frequency to in-
crease again. The motor operates forward.
4
CS3 activates and causes the direction to start to
change (FWD to REV).
5
The Run enable signal is set to OPEN, which causes
the frequency to go to 0. Configure the Run enable
signal with parameter 3.5.1.15.
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 P3.2.3 Keypad Stop
Button is Yes.)

operate in the reverse direction.
