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.

Pr.01-35 to Pr.01-42 is the V/f curve for the motor 2. When multi-function input terminals Pr.02- 01 to Pr.02-14 is set to 14 and enabled or switch to the Δ-connection, the AC motor drive will act as the 2nd V/f curve.

When start frequency is higher than the min. output frequency, drives’ output will be from start frequency to the setting frequency. Please refer to the following diagram for details. Fcmd=frequency command,

Fstart=start frequency (Pr.01-09), fstart=actual start frequency of drive,

Fmin=4th output frequency setting (Pr.01-07/Pr.01-41),

Flow=output frequency lower limit (Pr.01-11)
