 Drive Sequence and Run Command for Down Travel
 Travel Procedure
The down travel sequence is shown in the figure below. The Down Travel Run command and the Down Speed Command
must be set given according to this sequence.
 Leveling Control
In case of wrong setup (e. g. P1 parameter incorrectly entered), the car might move too slow at the end of the travel.
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.
In case the Down Travel RUN command is switched off before reaching zero value, the drive decelerates with Dwell at
Stop, if the frequency is still above Stop Dwell level. Refer to the figure below.
 Acceleration/Deceleration and S curve settings
The acceleration and deceleration ramps are set in C1-, while the S curves are defined in P2-15 to P2-18. Refer to the below.
