1 Control signal (CS) 1 has been activated causing the output
frequency to rise. The motor runs forward.
2 If start forward signal [CS1] and start reverse signal [CS2] are active
simultaneously, there is alarm 55 in LCD panel when P13.23 FWD/
REV conflict supervision=1.
3 CS1 has been inactivated the motor is still stopped though CS2 is
still active, and alarm 55 should be disappeared in a while time.
4 CS2 has been activated again causing the motor to accelerate (REV)
towards the set frequency.
5 CS2 inactivates and the frequency fed to the motor drops to 0 Hz.
6 CS1 has been activated and the motor accelerates (FWD) towards
the set frequency.

Explanations
7 Run enable signal is set to FALSE, which drops the frequency to 0 Hz.
The run enable signal is configured with par. 3.5.1.10
8 CS1 has been activated and the motor accelerates (FWD) towards
the set frequency because the Run enable signal has been set to
TRUE.
9 Keypad stop button is pressed and the frequency fed to the motor
drops to 0 Hz.
(This signal only works if Par.2.7 [Keypad stop button] = 1)
10 CS1 is opened and closed again which causes the motor to start.
11 CS1 has been inactivated and the frequency fed to the motor drops
to 0 Hz.
