Programming 48
Function: Option/Inv Selection 1
Setting: 2
The Option/Inv Selection function allows the user to select the source for the Run and speed commands between either the
Drive’s terminals or an optional communication card. When a digital input is programmed for the Option/Inv Selection
function (H1-0x= 2) that input will function as follows:
To switch the command source between the option card and the terminals be sure to program the following parameters:
•
Set b1-01 (Frequency Reference Selection) to 1 (Terminals).
•
Set b1-02 (Run Command Selection) to 1 (Terminals).
•
Set H1-0x (Input Terminal Function Selection) to 2.
Function: Multi-step Ref 1
Setting: 3
Function: Multi-step Ref 2
Setting: 4
The Drive can be programmed to step through four preset speeds and a jog. It is also possible to mix in the analog inputs as
speed references that can be chosen in place of the first and second preset frequency references. The selection of which preset
speed will be the active speed command is determined by the status of the digital inputs set for Multi-step Ref 1 (H1-0x= 3)
and Multi-step Ref 2 (H1-0x= 4). Changing the active speed command via the Multi-step References can be done while the
Drive is running.
The following table details which reference is active based on the status of the Multi-step Ref 1 and Multi-step Ref 2 inputs:
