V/f curve setting is usually set by the motor’s allowable loading characteristics. Pay special attention to
the motor’s heat dissipation, dynamic balance, and bearing lubricity, if 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. 01.32 ≥01.34≥01.36≥01.38.
There is no limit for the voltage setting, but a high voltage at low frequency may cause motor damage,
overheat, and stall prevention or over-current protection. Therefore, please use the low voltage at the low
frequency to prevent motor damage.
