 Leveling Control
In case of wrong setup (e. g. P1 parameter incorrectly entered), the pump might not generate
enough flow to move the car after deceleration from the selected speed to leveling speed.
To allow recovery in such a case, the drive decreases the speed automatically in steps down
to zero value in case the Down Travel RUN command is still on. Refer to the figure below.
