1.
Control signal (CS) 1 activates and causes the output
frequency to increase. The motor operates forward.
7.
CS1 activates and the motor accelerates (FWD) to the
set frequency.
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.
8.
The Run enable signal is set to OPEN, which causes
the frequency to go to 0. Configure the Run enable
signal with parameter P3.1.1.10.
3.
CS1 is becomes inactive and causes the direction to
start to change (FWD to REV) because CS2 is still
active.
9.
The Run enable signal is set to CLOSED, which does
not have an effect because a rising edge is necessary
for the start, even if CS1 is active.
4.
CS2 becomes inactive and causes the frequency to go
to 0.
10.
The STOP button on the keypad is pushed and the
frequency that is fed to the motor goes to 0. (This signal
works only if P3.2.3 Keypad Master Stop is Enabled.).
5.
CS2 activates again and causes the motor to accelerate
(REV) to the set frequency.
11.
CS1 is opened and closed again, which causes the
motor to start.
6.
CS2 becomes inactive and causes the frequency to go
to 0.
12.
CS1 becomes inactive and the frequency that is fed to
the motor goes to 0.
