Yaskawa E7L Drive Bypass - Manual (Page 142)

Programming 5 - 50
The Drive has five multi-function contact digital inputs. By programming parameters H1-01 through H1-05, the user can assign
specific functions to each input. Below is a table with a complete list of all of the digital input functions. The programming
manual has a more detailed description of each of the functions.
Following are descriptions of only those parameters that are required for Bypass operations and PI control.
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.
