1 Control signal (CS) 1 activates and causes the output
frequency to increase. The motor operates forward.
2 CS2 activates and causes the direction to start to
change (FWD to REV).
3 CS2 becomes inactive, which causes the direction to
start to change (REV to FWD), because CS1 is still ac-
tive.
4 CS1 becomes inactive and the frequency goes to 0.
5 CS2 activates, but the motor does not start because
CS1 is inactive.
6 CS1 activates and causes the output frequency to in-
crease again. The motor operates forward because
CS2 is inactive.

7 The Run enable signal is set to OPEN, which causes
the frequency to go to 0. Configure the Run enable
signal with parameter P3.5.1.15.
8 The Run enable signal is set to CLOSED, which cau-
ses the frequency to increase to the set frequency,
because CS1 is still active.
9 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.)
10 The drive starts because the START button on the
keypad was pushed.
11 The drive is stopped again with the STOP button on
the keypad.
12 The attempt to start the drive with the START button
is not successful, because CS1 is inactive.
