1 Reference 1 1. Sets b1-01 = 1 [Freq. Ref. Sel. 1 = Analog Input].
2. Sets H3-02 = 3 [AI1 Function Selection = Freq Ref/BIAS].
3. Sets H3-01 = 1 [AI1 Signal Level Select = -10 to +10V (Bipolar Reference)].
2 Reference 2 1. Sets H3-06 = 1 [AI3 Function Selection = AuxFreqRef1].
2. Sets H3-05 = 1 [AI3 Signal Level Select = -10 to +10V (Bipolar Reference)].
3 Signal type of analog input Set DIP switches S1-1 and S1-3 on the control circuit board to the V-side (voltage).
Note:
Set this before you energize the drive.
4
Reference 3 Sets the value of d1-03 [Reference 3].
5 Reference 4 Sets the value of d1-04 [Reference 4].
6 Reference 5 Sets the value of d1-05 [Reference 5].
7 Jog Reference Sets d1-17 [Jog Reference] to the jog speed.
8 External digital input (3
inputs)
Set Multi-Step Speed Reference 1 to 3 [H1-xx = A, B, C] to one of the MFDI terminals DI1 to DI8.
9 JOG command Set H1-xx = 6 [Jog Reference] to one of the MFDI terminals DI1 to DI8.
Use the Maximum 17-Step Speed with All Digital Inputs
This section is the procedure to set the 17-step speeds (17 types of frequency references) without an analog input.

1 Reference 1 1. Set b1-01 = 0 [Freq. Ref. Sel. 1 = Keypad].
2. Sets the value of d1-01 [Reference 1].
2 Reference 2 1. Sets H3-06 = 0 [AI3 Function Selection = Through Mode], and disables the analog reference.
2. Set d1-02 [Reference 2].
3 Reference 3 1. Sets H3-10 = 0 [AI2 Function Selection = Through Mode], and disables the analog reference.
2. Set d1-03 [Reference 3].
4 Reference 4 Set d1-04 [Reference 4].
5 Reference 5 to 16 Sets the values of d1-05 to d1-16 [Reference 5 to Reference 16].
6 Jog Reference Sets d1-17 [Jog Reference] to the jog speed.
7 External digital input (4
inputs)
Set Multi-Step Speed Reference 1 to 4 [H1-xx = A, B, C, D] to one of the multi-function digital input terminals DI1 to DI8.
8 JOG command Set H1-xx = 6 [Jog Reference] to one of the multi-function digital input terminals DI1 to DI8.
Multi-step Speed Operation Combinations
Refer to Table 12.23 and Figure 12.54 for information about multi-step speed reference combinations. The
selected frequency reference changes when the combination of digital input signals from an external source
changes.
