4 Start-Up Programming & Operation
Setting d1-18 = 0
Up to eight speed references can be set using parameters d1-01 to d1-08. The drive starts with an Up or Down command,
and stops when the Up or Down command is removed. When d1-18 = 0, parameters d1-19 through d1-23 will not be
displayed.
Setting d1-18 = 3
Allows seven speed references to be set using parameters d1-02 to d1-08. The drive starts with an Up or Down command,
and stops either when all three input terminals that set the speed reference are released, or when the Up/Down command
is released. When d1-18 = 0, parameters d1-19 through d1-23 will not be displayed.
Separate Speed Inputs (d1-18 = 1 or 2)
Six different speed settings (defined in the parameters d1-19 to d1-24 and d1-26) can be set and selected using four digital
inputs.
Speed Selection
When d1-18 = 1 or 2, multi-function digital inputs are preset as shown below.
Terminal Parameter Number
S3
S5
S6
Different speed settings can be selected depending on the assignment of the speed selection digital inputs (H1-) as
shown in the table below.
Note: Parameters d1-19 through d1-26 are displayed only if d1-18 is set to 1 or 2.
Selected Speed
Nominal Speed (d1-19)
Intermediate Speed 1 (d1-20)
Intermediate Speed 2 (d1-21)
Intermediate Speed 3 (d1-22)
Releveling Speed (d1-23)
Leveling Speed (d1-26)
Zero Speed
0 = Off, 1 = On, A = 0 when d1-18 = 2 and no influence when d1-18 = 1, 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. 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.
