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 that is fed
to the motor goes 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 does
not have an effect, because a rising edge is necessa-
ry for the start, even if CS1 is 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 CS1 is opened and closed again, which causes the
motor to start.
12 CS1 becomes inactive and the frequency that is fed
to the motor goes to 0.
