Typical Setting of the V/f Pattern
Set the V/f pattern according to the application as described below. For
400-V Class Inverters, the voltage values (n10, n13, and n15) should be
doubled. When running at a frequency exceeding 50/60 Hz, change the
Maximum Output Frequency (n09).
Note: Always set the maximum output frequency according to the motor char-
acteristics.
1. For General-purpose Applications
2. For Fans/Pumps
3. For Applications Requiring High Starting Torque
Increasing the voltage of the V/f pattern increases motor torque, but
an excessive increase may cause motor overexcitation, motor over-
heating, or vibration.
