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.
For the V/f curve setting, it should be 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 the low frequency may cause motor damage,
overheat, stall prevention or over-current protection. Therefore, please use the low voltage at
the low frequency to prevent motor damage.
V/F curve would only function as Pr. 00-09= 0 or 1 (under V/F control mode) and Pr. 00-10=0.
