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.
No. Parameter Name Setting Range Default
d1-01 to d1-16 Frequency Reference 1 to 16 0.00 to 400.00 Hz <1> 0.00 Hz
d1-17 Jog Frequency Reference 0.00 to 400.00 Hz <1> 6.00 Hz
<1> The upper limit is determined by the maximum output frequency (E1-04) and upper limit for the frequency reference (d2-01).
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:
• Multi-Step Speed 1
Set b1-01 to 1 to set terminal A1 analog input to Multi-Step Speed 1.
Set b1-01 to 0 when setting d1-01, Frequency Reference 1, to Multi-Step Speed 1.
• Multi-Step Speed 2
Set H3-06, Terminal A3 Function Selection, to 2 (Auxiliary Frequency Reference 1) when setting terminal A3 analog input
to Multi-Step Speed 2.
