 Determines the AC motor drive's Maximum Output Frequency. All the AC motor drive frequency
command sources (analog inputs -10–10 V) are scaled to correspond to the output frequency
range.

 You usually set the V/F curve according to the motor's allowable loading characteristics. Pay
special attention to the motor's heat dissipation, dynamic balance, and bearing lubrication when
the loading characteristics exceed the loading limit of the motor.
 The frequency setting of V/F curve must be set according to this rule: Pr.00-13 ≥ Pr.03-51 ≥
Pr.03-53 ≥ Pr.03-55. There is no limit for the voltage setting, but a high voltage at low frequency
may cause motor burnout, overheating, and trigger stall prevention or over-current protection.
Use low voltages at low frequencies to prevent motor damage or drive malfunction.
