• Typical setting of V/f pattern
Set the V/f pattern according to the application as described below. For
400V class, the voltage values (n10, n13, and n15) should be doubled.
When running at a frequency exceeding 50Hz/60Hz, change the maximum
output frequency (n09).
Note: Be sure to set the maximum output frequency according to the motor characteristics.

Increasing voltage of V/f pattern increases motor torque, but an excessive
increase may cause motor overexcitation, motor overheat or vibration.
Note : n12 is to be set to motor rated voltage.
