• 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 excessive increase may
cause motor over excitation, motor overheat, or vibration.
