Yaskawa AC Drive Z1000 - Manual (Page 170)

No. Parameter Name Setting Range Default
d1-01 to d1-04 Frequency Reference 1 to 4 0.00 to 240.00 Hz <1> <2> 0.00 Hz <2>
d1-16 Frequency Reference 16 0.00 to 240.00 Hz <1> <2> 0.00 Hz <2>
d1-17 Jog Frequency Reference 0.00 to 240.00 Hz <1> <2> 6.00 Hz <2>
<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).
Multi-Step Speed Selection
To use several speed references for a multi-step speed sequence, set the H1-oo parameters to 3 and 4. To assign the Jog
reference to a digital input, set H1-oo to 6.
Notes on using analog inputs as Multi-Speed 1 and 2:
• 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 or H2-06 = 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 Table 4.24 . Figure 4.32 illustrates the multi-step speed selection.

n d2-03: Master Speed Reference Lower Limit
Sets a lower limit as a percentage of the maximum output frequency that will only affect a frequency reference entered from
the analog input terminals (A1 or A2) as the master speed reference. This is unlike parameter d2-02, which affects all frequency
references regardless of their source.
Note: When lower limits are set to both parameters d2-02 and d2-03, the drive uses the greater of those two values as the lower limit.
