◆ d1: Frequency Reference
■ d1-01 to d1-17: Frequency Reference 1 to 16 and Jog Frequency Reference
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.
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-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, the frequency reference source must be assigned 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), then 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.
No.
<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).
Parameter Name Setting Range Default
d1-01 to d1-16 Frequency Reference 1 to 16 0.00 to 400.00 Hz <1> <2> 0.00 Hz <2>
d1-17 Jog Frequency Reference 0.00 to 400.00 Hz <1> <2> 6.00 Hz <2>
