Operating Instruction - Frequency Inverter 230V / 400V ... - opis.cz

If the mains failure with or without shutdown takes so long that the frequency invertershuts off completely (LEDs = OFF), the frequency inverter will be in the"Standby" state when the mains supply is restored. If the inverter is released again,the drive will start. If the drive is to start automatically after restoration of the mainssupply and if the inverter is released permanently, Operation Mode 651 of Auto Startmust be switched on.ParameterSettingsNo. Description Min.

The frequencychange necessary for this is parameterized by the generator reference current valueor rather the ramp. The Gen. Ref. Current Limit 683 or the ramp Mains Support Deceleration673 defines the maximum deceleration of the drive necessary in order toreach the voltage value Reference Mains Support Value 672. The Acceleration onMains Resumption 674 replaces the set values of the ramp parameters Acceleration(Clockwise) 420 or Acceleration Anticlockwise 422 if the value set in the factory ischanged. The voltage control in a mains failure changes from the frequency limitShutdown Threshold 675 from Reference Mains Support Value 672 to the ReferenceShutdown Value 676.ParameterSettingsNo. Description Min.
