inverter decelerates to the leveling speed (d1-17) when the selected speed signal is removed. Inspection Speed
can not be selected as travel speed. The higher speed has priority over the leveling speed, i.e. as long as a
higher speed is selected, the leveling signal is disregarded (see the fig. below)
The inverter stops when the leveling signal or the Up/Down signal is removed.

When the leveling speed command is not selected for any digital input, the inverter decelerates to the leveling
speed (d1-17) when the selected speed signal is removed. Inspection Speed can not be selected as travel speed
To select the leveling speed as travel speed the frequency reference loss detection must be disabled (S3-09=0).
The inverter stops when the direction signal Up/Down is removed.
