Note 1. Set theparameters sothat thefol-
lowing condition will be satisfied.
n016 n014 < n013 n011
Note 2. The value set in n015 will be
ignored if parameters n016 and
n014 are the same in value.

·The vertical-axis load or the load with high viscous friction may require high torque at
low speed. If the torque is insufficient at low speed, increase the voltage in the low-
speedrangeby1V,providedthatnooverload(OL1orOL2)isdetected.Ifanoverload
is detected, decrease the setvaluesorconsider the use ofan Invertermodel or motor
with a higher capacity.
·Therequiredtorqueoffan or pump control increasesinproportiontothesquare ofthe
speed. By setting a quadratic V/f pattern to increase the voltage in the low-speed
range, the power consumption of the system will increase.
