• Energy-saving voltage lower/upper limit (n141, n142, n159,
n160)
Sets the upper and lower limits of the output voltage. When the value calculated in
the energy-saving control mode is larger than the upper limit (or smaller than the
lower limit), the value is output as a voltage reference value. The upper limit is set
to prevent over-excitation, and the lower limit is set to prevent stalls when the load
is light. The voltage limit is set for machines using 6Hz/60 Hz. For any voltage
other than 6Hz/60Hz, set the (value of the) voltage limit according to linear
interpolation. The parameters are set in % for 200V/400V inverters.
*Doubled for the 400V class inverters.
