What is the frequency converter through function?
Some inverter has this function, such as the ACS800 series has lost power across functions, can be in a temporary loss of power grid when using mechanical transducer can keep running, as long as the rotation of the motor and the inverter to provide energy, although the speed will decrease, but the converter will run normally (power mode), and if the grid connected inverter in the state power grid voltage recovery after the inverter can be immediately put into normal electric state.The undervoltage controller needs to be activated (parameter 20.06).
The default power loss time is 5S.Using DSU's high-power inverters, you need to set the time delay in DSU software to activate this function.The power down function is unique across some converter functions. In the power plant, semiconductor, petrochemical and other industries has been widely used to solve the power problem recurring and electricity, the massive economic losses caused momentary loss of power equipment downtime caused by continuous production. To protect the user to the greatest extent.
There are two modes of power down mode, 1 is power down mode, the motor is taxiing when starting,.2 is power down mode, and the motor is decelerated when it is started1, sliding mode: when the bus voltage is lower than the setting voltage bus 73%, inverter began to slide in power off set time (default is 0.5S). When the sliding is not shut down within the set time, bus voltage to rise to 82%, return to normal control. Acceleration transducer to the original state.This model is suitable for large inertia and light load
Frequency converter is an ideal motor stepless speed regulating device. It is mainly used in three-phase and two-phase asynchronous motors. It has the advantages of small start-up current, smooth operation and complete protection facilities. The utility model is suitable for stepless speed regulation of various equipment.
Inverter through function refers to:The converter can temporary loss of power in the power grid when using mechanical transducer can keep running, as long as the rotation of the motor and the inverter to provide energy, although the speed will decrease, but the converter will run normally (power mode), and if the grid connected inverter in state grid voltage recovery after the inverter can be immediately put into normal electric state.
