 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 -connection, the AC
motor drive will act as the 2nd V/f curve.
 The V/f curve for the motor 1 is shown as follows. The V/f curve for the motor 2 can be
deduced from it.
