Depending on the assignment of speed selection functions to the digital input (H1- settings), the different speed
settings can be selected like shown in the table below.
Selected Speed
Nominal Speed (d1-19)
Intermediate Speed 1 (d1-20)
Intermediate Speed 2 (d1-21)
Intermediate Speed 3 (d1-22)
Revelling Speed (d1-23)
Leveling Speed (d1-26)
Zero Speed
0 = Off, 1 = On
A: No influence when d1-18 = 1, 0 when d1-18 = 2
B: No influence
N/A = Not available
Higher Speed has Priority and the Leveling Speed Input is Assigned (d1-18 = 1 and H1- = 53) (Default)
The higher speed has priority over the leveling speed, meaning the leveling signal is disregarded as long as any other
speed selection input is active. The drive decelerates to the leveling speed (d1-26) when the selected speed reference
signal is removed.
Higher Speed Priority is Selected and the Leveling Speed Input is Not Assigned (d1-18 = 1 and H1- 53)
The drive decelerates to the leveling speed (d1-26) when the selected speed reference signal is removed.
If no speed reference is selected at start the drive will trigger an "FrL" fault. To disable Speed Reference Missing (FrL)
detection, set parameter S6-15 to "0". With this setting the drive starts using leveling speed if no other speed reference is
selected.
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.
