● 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.

● There is no limit for the voltage setting, but a high voltage at a low frequency may cause motor damage,

overheating, and trigger the stall prevention or the over-current protection; therefore, use low voltage at low

frequency to prevent motor damage or drive error.

● The diagram below shows the V/F curve for motor 1. You can use the same V/F curve for motor 2, motor 3, and

motor 4. For multi-motor selections, see the multi-function input terminal (Pr.02-01 to Pr.02-07) settings 83 and

84.

Common settings for the V/F curve:
