1 Control signal (CS) 1 activates and causes the output
frequency to increase. The motor operates forward.
2 CS2 activates, but it does not have an effect on the
output frequency, because the direction that is set
first has the highest priority.
3 CS1 becomes inactive and causes the direction to
start to change (FWD to REV), because CS2 is still ac-
tive.
4 CS2 becomes inactive and the frequency that is fed
to the motor goes to 0.
5 CS2 activates again and causes the motor to acceler-
ate (REV) to the set frequency.
6 CS2 becomes inactive and the frequency fed to the
motor drops to 0.
7 CS1 activates and the motor accelerates (FWD) to
the set frequency.

8 The Run enable signal is set to OPEN, which causes
the frequency to go to 0. Configure the Run enable
signal with parameter P2.5.1.10.
9 The Run enable signal is set to CLOSED, which cau-
ses the frequency to increase to the set frequency,
because CS1 is still active.
10 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.)
11 The drive starts because the START button on the
keypad was pushed.
12 The STOP button on the keypad is pushed again to
stop the drive.
13 The attempt to start the drive with the START button
is not successful, because CS1 is inactive.
