01/02 AWB8230-1413GB Controlled decelerationIf the mains power fails during controlled deceleration(PNU b050 = 01), deceleration starts as soon as the internal DClink voltage V DC falls below the threshold set under PNU b051.To ensure that the control electronics are supplied with power, thecurrent output frequency f O is reduced by the frequency jump setunder PNU b054. The motor then runs in regenerative mode <strong>and</strong>feeds the internal DC link voltage V DC . Deceleration now takesplace after the set deceleration ramp (PNU b053). If, due to a highmass inertia, the internal DC link voltage V DC be<strong>com</strong>esexcessively high, the deceleration ramp is interrupted until thevoltage falls below the threshold defined under PNU b052.U DCPNU b052PNU b051U UVf OtPNU b054PNU b053PNU b053tFigure 148: Function chart for controlled decelerationU DC : Internal DC link voltageU UV : Voltage threshold for the control electronicsf O : Output frequencyPNU Name Adjustable in RUN mode Value Function WENormalExtendedb050b051b052b053b054ControlleddecelerationStartingvoltage fordecelerationVoltage forramp stopDecelerationtime<strong>Frequency</strong>jump– – 00 Controlled deceleration is not active. 0001 Controlled deceleration is active.– – 0 to 1000 V When the internal DC link voltage falls below this value,controlled deceleration starts– – 0 to 1000 V When the internal DC link voltage rises again, thedeceleration ramp PNU b053 is interrupted.– – 0.01 to 3600 s During this time, the motor is decelerated. 1.00– – 0.00 to10.00 HzThe frequency inverter reduces the output voltage by thisvalue so that the motor works in regenerative mode.0.00.00.00141
