If the voltage is too high when the motor is at low frequencies, it may cause motor damage,
overheating, and may trigger stalling or over-current protection. To prevent motor damage or
motor fault, be careful when you set the voltage.
The diagram below shows the V/F curve for motor 1. You can also find the V/F curve for motor 2
from the same diagram. For multi-motors selection, refer to multi-function input terminal settings
83 for Pr.02-01–02-05.
Common settings for the V/F curve:
(1) General purpose
(2) For fan and hydraulic machinery
