Startup Profile Function IllustrationThe parameters that are related to the startup profile function are listed below.01 - Generator Output Voltage03 - Generator Type06 - Knee Frequency10 - Underfrequency PointThe startup profile function sets up the volts per hertz profile (V/Hz) during startup only. The digital voltage regulator will begin to build voltage following a 1:1 volts per hertz profile after the configured under frequency point (parameter :10) has been reached. When the speed reaches the knee frequency point (parameter :06), the loading/stopping profile takes effect.The startup profile function will not be initiated again unless the frequency drops below the underfrequency point (parameter :10). The underfrequency point is defaulted to 25 Hz, with a range of 20 to 40 Hz. This is the same underfrequency setpoint used by the loading/stopping setpoint.The startup V/Hz slope is set to 1. The startup V/Hz slope is not adjustable. A V/Hz slope of 1 indicates that a change of 1% voltage will result for every 1% of frequency change.The knee frequency point is the point above which the digital voltage regulator will regulate to the voltage specified by the generator output voltage parameter.The generator type selects whether the frequency being detected is the actual generator output frequency (SE) or one of the permanent magnet (PM) frequencies.
