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.
