■
Up to 17 preset frequency references (including the Jog reference) can be programmed in the drive. The drive lets the
user switch between these frequency references during run by using the digital input terminals. The drive uses the
acceleration and deceleration times that have been selected when switching between each frequency reference.
The Jog frequency must be selected by a separate digital input and overrides all other frequency references.
The multi-speed references 1, 2, and 3 can be provided by analog inputs.

<1> The upper limit is determined by the maximum output frequency (E1-04) and upper limit for the frequency reference (d2-01).
<2> Setting units are determined by parameter o1-03. The default is "Hz" (o1-03 = 0) in V/f, V/f w/PG, OLV, CLV, and OLV/PM control modes.
The default for AOLV/PM and CLV/PM control modes expresses the frequency reference as a percentage (o1-03 = 1).
Multi-Step Speed Selection
To use several speed references for a multi-step speed sequence, set the H1- parameters to 3, 4, 5, and 32. To assign
the Jog reference to a digital input, set H1- to 6.
Notes on using analog inputs as Multi-Step Speed 1, 2, and 3:
• Multi-Step Speed 1
When setting terminal A1's analog input to Multi-Step Speed 1, set b1-01 to 1, and when setting d1-01 (Frequency
Reference 1) to Multi-Step Speed 1, set b1-01 to 0.
