11-12 SP600 AC Drive User Manual
Sets the continuous current operating level for the motor.
This parameter can be used to raise the level of current that will
cause the motor thermal overload to trip. The effective overload
factor is a combination of parameters 47 and 48.
Motor FLA x OL Factor = Operating Level (continuous)
Sets the method of motor torque production.
• Sensrls Vect maintains consistent magnetizing current up to base
speed, and voltage increases as a function of load.
• SV Economize allows the drive to automatically adjust output
voltage as the load changes to minimize current supplied to the
motor. The voltage is adjusted by means of flux current adaption.
• Custom V/Hz allows for tailoring the volts/hertz curve by adjusting
parameters 54, 55, 70, 71 and 72.
