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.
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.
Pr.01-35 to Pr.01-42 is the V/f curve for the motor 2. When multi-function input terminals
