Q:What does the brake unit on the inverter mean?
In order to digest this part of the energy, the transducer consumes the energy of the feedback current through the resistor.If the inverter is more advanced, this part of the current can also be sent to the call back network through the controlled rectifier bridge. There's no braking resistance.
Q:What is the difference between a frequency converter and a saver?
According to the frequency above 3 disadvantages, we developed and produced for Saver series under different conditions, based on frequency conversion technology, according to the field of electricity, increase control cabinet, electric / power conversion system, load detection and control system, input and output filter, DC reactor device etc.. The economizer has 4 advantages over the inverter:
Q:What is the difference between frequency converter and UPS?
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment. The frequency converter is mainly composed of rectifier (AC DC converter), filter, inverter (DC AC converter), brake unit, drive unit, detection unit, micro processing unit and so on. Inverter by internal IGBT drive voltage and frequency off to adjust the output power, the power supply voltage required to provide according to the actual needs of the motor, so as to achieve the purpose of speed, energy saving, in addition, there are a lot of protection drive, such as over-current, over-voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.UPS is an uninterruptible power supply, including an energy storage device, a rectifier, inverter as the main component of the regulator, frequency stabilized AC power supply. The main use of battery energy storage power supply device to provide uninterrupted computer / server, storage equipment, network equipment, computer communication network system and industrial control system, need continuous operation of industrial equipment in power outages. When the power input is normal, UPS electric voltage supplied to the load, the UPS is an AC electric regulator, it is also to the storage device such as a battery charging; when the power interruption (outage), UPS immediately to the storage device (such as batteries or fly wheel the electric energy storage system), continue to supply alternating current to the load by the method of inverse transformation, the load to maintain normal working and protect the load of software and hardware is not damaged.
Q:What are the key points of frequency converter maintenance?
Frequency converter daily patrolDo the inverter daily inspection and inspection work, inspection contents mainly include: ambient temperature, humidity is required, ventilation windows is good; the inverter air inlet and outlet is blocked by dust or too much dust; inverter operation parameter is normal, there is no alarm; cabinet fan the operation is normal; if there is abnormal sound or vibration transducer; capacitor whether overheat.
Q:How can I learn the converter well?
1. overload or acceleration and deceleration in case of braking resistance to increase, to help the loss of mechanical energy, you may have to set the corresponding parameters. 2. inverter motor with a little weak, if there is an advanced mode (magnetic flux vector control and the like), enable this function can play a maximum motor ability (the specific reference manual, cheap converter is not it) 3. serial communication change frequency, need to understand the communication protocol converter, usually have instructions to write specific parameters of frequency message reference manual.
Q:Can not directly through the PLC, ABB converter and Kingview software communication between them?
ABB converter supports MODBUS protocol, can be directly connected to the ModbusRTU in your choice of Kingview, device configuration, set up converter address directly in Kingview read the corresponding parameters can be
Q:Does anyone know how to solve the problem of frequency converter interference?
You can try using the following methods:Solution of interference caused by circuit coupling:The PLC and monitoring equipment are powered by isolated transformers.
Q:What does the RUN key on the inverter mean? How do you use it?
In general, when selecting panel operations (when the panel of the inverter is the control source of the inverter), it is the meaning of the "running" button. Press it, the converter will run, turn or reverse
Q:Frequency converter, fault, contact action
The frequency converter has 1-2 relay outputs, that is, digital output. By default, most of the output of the fault is the relay. The general definition of the 2 relays is defined as a running output and a fault output.
Q:What do you mean by the capacity of the inverter and the capacity of the motor?
Because the motor consumes active power and consumes reactive power, and the reactive power is also occupied, the motor with 70KW can only be usedThe power is known to everyone
