Leveling Speed has Priority and the Leveling Speed Input is Assigned
(d1-18 = 2, H1-
= 53)
The leveling signal has priority over other speed references. The drive decelerates to the
leveling speed (d1-26) when the leveling speed selection input is activated.
Leveling Speed has Priority and the Nominal Speed Input is Not Assigned
(d1-18 = 2, H1-
50)
The drive runs at nominal speed (d1-19) when no speed selection input is set. When the
leveling speed signal is set, the drive decelerates to the leveling speed. The leveling speed
signal has priority over all other speed signals.

CAUTION
This sequence can be risky if the leveling speed selection does not work correctly (broken wire, etc.) as the drive
will always run at nominal speed.
