d1-01 to d1-04: Frequency References 1 to 4
The drive lets the user switch between up to 5 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 and 2 can be provided by analog inputs.
No.
d1-01 to d1-04
<1> The upper limit is determined by the maximum output frequency (E1-04) and upper limit for the frequency reference (d2-01). Parameter d2-01 is
not accessible.
<2> Setting units are determined by parameter o1-03. The default is "Hz" (o1-03 = 0).
Multi-Step Speed Selection
To use several speed references for a multi-step speed sequence, set the Z2-oo (DI-oo Select) parameters to 5 (S5) and 6
(S6). To assign the Jog reference to a digital input, set Z2-oo (DI-oo Select) to 7 (S7) .
Notes on using analog inputs as Multi-Speed 1 and 2:
• The first frequency reference (Multi-Speed 1) comes from the source specified in Z1-07. When using an analog input terminal
to supply the frequency reference, assign the frequency reference source to the control terminals (Z1-07 = 1).
• When an analog input is set to "Auxiliary frequency 1" (H3-02 or H3-10 = 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.
Select the different speed references as shown in
Frequency Reference 1 (set in b1-01)
Frequency Reference 2
(d1-02 or input terminal A1, A2)
Frequency Reference 3
(d1-03 or input terminal A1, A2)
Frequency Reference 4 (d1-04)
<1> The Jog frequency overrides all other frequency references.
