I/O Control Parameters

Active Logic Function
Two logic input functions can be configured to be active. The logic input functions assigned to parameters [Logic
Funct 1 active] (F108) and [Logic Funct 2 active] (F110) will continuously affect drive operation. See table
beginning on page 91 for a list of available logic input functions.
If F110 is not set to 1 (logic function [Run permissive]), a logic input should be assigned to the [Run
permissive] logic function to enable the motor to start.
Preset Speeds
A maximum of seven preset speeds can be selected by 4 logic inputs (F, R, RES, or VIA). Preset speed control
is only active when the drive is in logic input control (
[Command mode sel] (CMOd) = 0).
For one preset speed, assign a logic input to function 6.
For up to three preset speeds, use two logic inputs for functions 6 and 7.
For up to seven preset speeds, use three logic inputs for functions 6, 7, and 8.
Preset speed commands take priority over speed commands from any other source. For more information on
preset speeds, see page 91
. See page 42, for wiring instructions and timing diagram.
