The maximum output frequency f
max
is the highest frequency allowed to be output by the inverter.
The maximum output voltage Vmax is the output voltage of the inverter when it runs at the basic
operating frequency, which corresponds to the rated voltage of the motor when using a standard AC
motor. See the motor nameplate.
The upper frequency limit f
H
and lower frequency limit f
L
are the maximum and minimum
frequencies of motor operation set by the user according to the requirements of the production
process.

P70.02 is the D axis current preset limiting value. Exceeding this value will enter the speed reduction
control.
P70.03 is the ID limiting gain, which determines amplitude value of the speed reduction.
