Ovld Start
Level
[A518]
(Motor Overload Start Level)
This parameter defines maximum current
at which motor can run continuously. This
parameter is also one of the two
parameters that define the motor overload
curve. Units in percent of rated current.
For more information, see OVLD START
LEVEL on page 78.

) This parameter sets amount
of inductance in flux producing equivalent
circuit of the vector controlled PM motor.
Higher inductances are used for higher
horsepower motors., but it is best if
obtained from motor specifications.
