If the voltage exceeds the value set by the parameter Reference DC-Link Limitation680, the deceleration is reduced in such a way that the DC link voltage is regulated tothe set value. If the DC link voltage cannot be regulated to the set reference value bythe reduction of the deceleration, the deceleration is stopped and the output frequencyraised. The output frequency is calculated by addition of the parameter valueMax. <strong>Frequency</strong> Rise 681 to the frequency at the operating point of the controllerintervention.ParameterSettingsNo. Description Min.

A mainsfailure is recognized if the DC link voltage has fallen below the set value of the parameterMains Failure Threshold 671. If a mains failure is recognized, the controllertries to regulate the DC link voltage to the value set with the parameter ReferenceMains Support Value 672. For this, the output frequency is continuously reduced andthe motor with its rotating masses put into generator operation. The reduction of theoutput frequency is done according to the configuration with a maximum of the currentset by the parameter Gen. Ref. Current Limit 683 or the ramp Mains SupportDeceleration 673.The threshold values of the voltage controller are calculated starting with the currentDC link voltage leading from the parameters Mains Failure Threshold 671 and ReferenceMains support Value 672.If the mains voltage is restored before a switch-off is effected by the mains undervoltagedetection system, the drive is accelerated to its reference frequency at the setacceleration or according to the parameter Acceleration on Mains Resumption 674. Ifthe value of parameter Acceleration on Mains Resumption 674 is set to the defaultvalue of 0.00 Hz/s, the drive is accelerated at the values set for the ramp parametersAcceleration (Clockwise) 420 or Acceleration Anticlockwise 422.146 02/06

As an alternative, supply through the frequencyinverter is to be used.Operation mode mains failure regulation (continued)Ud, fUd676672671f673 or 683Mains voltage675Power failure Off tThe DC link voltage which is available in the case of a power failure is supplied by themotor. The output frequency is continuously reduced and the motor with its rotatingmasses is switched over to generator operation. The maximum reduction of the outputfrequency is done at the current set by the parameter Gen. Ref. Current Limit683 or the ramp Mains Support Deceleration 673 until the frequency limit ShutdownThreshold 675 is reached. If the energy of the system for bridging the mains failure isnot sufficient, the delay occurs at maximum ramp gradient as from the ShutdownThreshold 675.The time required until the motor has come to a standstill results from the regenerativeenergy of the system which results in an increase in the DC link voltage. The DClink voltage set with the parameter Reference Shutdown Value 676 is used by thevoltage controller as a control figure and kept constant. The voltage rise enables optimizationof the braking behavior and the time until the drive has come to a standstill.The behavior of the controller can be compared to stopping behavior 2 (Shutdown +Stop), as the voltage controller brings the drive to a standstill at the maximum decelerationramp and supplies it with the remaining DC link voltage.If the mains voltage is restored after the shutdown of the drive but before the undervoltageswitch-off has been reached, the frequency inverter signals a fault. The controlunit displays the fault message "F0702".If the mains failure without shutdown (Shutdown Threshold 675 = 0 Hz) takes solong that the frequency has been reduced to 0 Hz, the drive is accelerated to the referencefrequency when the mains supply is restored.02/06 147
