When selecting customized V/F curve function, users can set the reference channels and
acceleration/deceleration time of voltage and frequency respectively, which will form a real-time V/F
curve through combination.
Note: This kind of V/F curve separation can be applied in various frequency-conversion power sources,
however, users should be cautious of parameter setup as improper setup may damage the machine.
