Parameter Description
5.3 Base Frequency and Base Voltage (P.3, P.19, P.47)
P.3 “Base Frequency”
P.19 “Base Voltage”
P.47 “Second base frequency”
The maximum output voltage of the inverter is referred to as the base voltage.
If the output frequency is lower than the base frequency, the output voltage of the inverter will
increase with the output frequency. If the output frequency has reached the base frequency
(P.3/P.47), the output voltage will be equal to the base voltage. If the output frequency exceeds the
base frequency and increase continuously, the output voltage will be clamped to the base voltage.

<Setting>
• The base frequency is set through P.3 and P.47.
• If RT is on, P.47 Second Base Frequency is valid (Note 1).
• The base voltage is set through P.19 (Note 2).
Note: 1. The second function is valid only when P.44 9999.
2. If P.19=9999, the maximum output voltage of the inverter will depend on the value of the power supply
voltage.
3. RT in this paragraph is referred to as the multi-function control terminals. For selecting the function and
use of the multi-function control terminal, please refer to P.80~P.84, P.86
. For the wiring, please refer to
Section 3.5.6
