d1: Frequency Reference

n d1-01 to d1-17: Frequency Reference 1 to 16 and Jog Frequency Reference
The drive lets the user switch between up to 17 preset frequency references during run (including the Jog reference) through
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 overrides all other frequency references and must be selected by a separate digital input.
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-oo parameters to 3, 4, 5, and 32. To assign the
Jog reference to a digital input, set H1-oo to 6.
Notes on using analog inputs as Multi-Speed 1, 2, and 3:
• The first frequency reference (Multi-Speed 1) comes from the source specified in b1-01. When using an analog input terminal
to supply the frequency reference, assign the frequency reference source to the control terminals (b1-01 = 1).
• When an analog input is set to "Auxiliary frequency 1" (H3-02, H2-06, or H2-10 = 2), the value set to this input will be used
as the Multi-Step Speed 2 instead of the value set to parameter d1-02. If no analog inputs are set for "Auxiliary frequency
1", then d1-02 becomes the reference for Multi-Step Speed 2.
