 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.01-01 ≥ Pr.01-03 ≥ Pr.01-05 ≥
Pr.01-07. 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 l
 ow voltages at low frequencies to prevent motor damage or drive malfunction.

 Determines the starting frequency. When the starting frequency (Pr.01-09) is larger than the output
frequency (Pr.01-11), the frequency output starts when the starting frequency (Pr.01-09) reaches the F
command.
