Note Values
will be
set in 0.1-Hz increments if the frequency is less than 100 Hz and
1-Hz increments if the frequency is 100 Hz or greater.
Output
voltage (V)
Note 1. Set the parameters so that
the
following
condition will be
satisfied.
n14 x n12 < n11 x n09
Note 2. The
value set in n13 will be ig
-
nored if parameters n14 and
n12 are the same in value.
Frequency (Hz)
•
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-
speed
range by 1 V
, provided that no overload (OL1
or OL2) is detected. If an overload
is detected, decrease the set values or consider the use of an Inverter model with a
higher capacity.
•The
required torque of fan or pump control increases in proportion to the square of the
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.
