Multi-Step Speed Selection
To use several speed references for a multi-step speed sequence, set the H1-
the Jog reference to a digital input, set H1-
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.
• When the an analog input is set to "Auxiliary frequency 2" (H3-02, H2-06, or H2-10 = 3), then the value set to this
input will be used as the Multi-Step Speed 3 instead of the value set to parameter d1-03. If no analog inputs are set for
"Auxiliary frequency 2", then d1-03 becomes the reference for Multi-Step Speed 3.
The different speed references can be selected as shown in
