
Speed Selection Using Digital Inputs (b1-01 = 0)
Use parameter d1-18 to determine how different travel speeds are selected by digital inputs.

0
Multi-speed inputs 1, Speed references are set in d1-01 to d1-08
1 (default)
Separate speed inputs, Speed references are set in d1-19 to d1-24 and d1-26, Higher speed has priority
2
Separate speed inputs, Speed references are set in d1-19 to d1-24 and d1-26, Leveling speed has priority
3
Multi speed inputs 2, Speed references are set in d1-02 to d1-08, Stop if no speed selection input is enabled

Multi-Speed Inputs 1, 2 (d1-18 = 0 or 3)
Speed Selection
When d1-18 = 0 or 3, multi-function digital inputs are preset as shown below.

Setting d1-18 = 0
Eight separate speed settings (defined in parameters d1-01 to d1-08) can be selected by three digital input signals.
Setting d1-18 = 3
Seven separate speeds settings (defined in parameters d1-02 to d1-08) can be selected by three digital input signals. The
drive stops when no speed is selected (i.e., all speed selection inputs are switched off).

Separate Speed Inputs (d1-18 = 1 or 2)
With this setting, six different speeds (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.
