n C7-60: Output Voltage Limit Mode Selection
Sets the mode to limit the output voltage.
Set this parameter to 0 (Harmonic suppression priority mode) to give priority to harmonic suppression. The maximum output
voltage is automatically limited to suppress harmonics.
Set this parameter to 1 (High output voltage mode) to give priority to the output voltage over harmonic suppression. The
effectiveness of harmonic suppression will be reduced because the maximum output voltage will be used.
Note: For drives with software versions PRG: 1021 or later, the default setting is 0 (Harmonic Suppression Priority Mode) when in Advanced
Open Loop Vector Control for PM (A1-02 = 6).
No.

n d1-01 to d1-04, d1-16, and d1-17: Frequency References 1 to 4, 16, and Jog Frequency
Reference
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.

<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.
