Q: Why does the frequency converter cause interference?: Shielded interference source: shielded interference source is an effective way to suppress interference. Usually the inverter itself with iron shielding, can not let the leaked electromagnetic interference, but the output line frequency converter is best to use steel shielding, in particular to an external signal (4~20mA signal output from the controller) control of inverter, the control signal line is as short as possible (usually less than 20m), and must use the shielded twisted pair and the main power line and the control line (AC380) and (AC220V) completely separated. In addition, the circuit of electronic sensitive equipment in the system also adopts shielded twisted pair, especially the pressure signal. All signal lines in the system must not be placed in the same pipe or slot as the main electrical line and control line. To make the shield effective, the shield must be grounded reliably.

Q: What are the key points of frequency converter maintenance?: 1., regular cleaningAlways check the frequency converter regularly and keep the environment clean and dry. It is strictly prohibited to place sundries near the frequency converter, and someone should regularly clean the frequency converter, blow it out, keep the cleanliness of the converter and the ventilation of the air duct.2. treatment methodsIf it is found within the inverter or radiator plate dust and debris falling into, should promptly use compressed air to blow off. Clean air filter, cooling air duct and interior dust. When it is found that the conductor and insulator have corrosion, it should be promptly cleaned with alcohol.For continuously running inverters, the running state can be visually checked from outside. Periodically inspect the converter and check if there is any abnormality when the converter is running. The following tests should normally be carried out:

Q: What is frequency conversion? What is the function of frequency converter?: Frequency conversion energy savingThe frequency converter energy saving mainly displays in the fan, the water pump application. In order to ensure the reliability of production, all kinds of production machinery in the design and use of power driven, have left a certain amount of surplus. When the motor can not run under full load, in addition to the power driven requirements, the excess torque increases the consumption of active power, resulting in waste of energy. Speed control method of fan and pump equipment traditional by regulating the entrance or exit of the baffle, valve opening to regulate air flow and water supply, its high input power, and a large amount of energy consumption in the process of the baffle and valve closure. When using the variable frequency speed regulation, if the flow requirements are reduced, by reducing the speed of the pump or fan can meet the requirements.

Q: What is the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?: Vibration and shock. The control cabinet equipped with frequency converter will cause bad electrical contact when subjected to mechanical vibration and shock. At this time, in addition to improving the mechanical strength of the control cabinet, away from the vibration source and shockShock source should also use shock rubber pads, fixed outside the control cabinet and internal electromagnetic switches and other parts of the vibration generated. After running for a period of time, the equipment should be inspected and maintained.

Q: What's the function of this brake unit?: 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 TTK converter produced?: Characteristic：Compact structure design, flexible installation, advanced control algorithm: space voltage vector control technology, power failure restart, automatic voltage adjustment, dead time compensation, energy saving operation,The main and auxiliary setting, built-in PID, simple PLC, oscillating frequency and zero frequency difference, length control, precision control requirements; design and test in accordance with international standards, to ensure the reliability of the product; choose rich accessories.

Q: What role does input and output reactor play?: The working principle of frequency converter:Normally, a device that changes the alternating current of voltage and frequency to a voltage or frequency variable alternating current is called a frequency converter". The device must first convert three-phase or single-phase AC to direct current (DC). Then the direct current (DC) is converted to three-phase or single-phase alternating current (AC). The frequency converter changes the output frequency and voltage at the same time, that is to change the N0 on the motor running curve, so that the motor running curve is parallel and downward. Therefore, the frequency converter can make the motor start with a smaller starting current to obtain a larger starting torque, that is, the frequency converter can start heavy load, and the inverter has the basic functions of voltage regulation, frequency modulation, voltage regulation, speed regulation and other basic functions

Q: I do mining equipment, recently I used ABB frequency converter to put into our equipment, but the problem of interference really gives me a headache! We have two pieces of equipment of SIEMENS S7-200 PLC, and is used in point to point protocol communication with each other, when the converter work PLC communication interference! There are monitoring equipment, converter work, there are a large number of snowflakes on the screen, simply do not see! Not even an internal phone! I've done well in grounding, but I still can't do it! Is there any master who can teach me a trick?: 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: Can a power converter be used in a motor with small power? Will it burn the motor?: If it is overloaded with constant torque, the vector control or DTC, then not power motor inverter below 1/4, otherwise the inverter to motor "modeling" is not accurate, easy to control and protection of the disorder is not perfect.

Q: Frequency converter OC alarm, what's the matter?: Description of the OC fault in the inverter manual, following several explanations: the load side short-circuit current greater than OC, run jump failure is two times; the output of the inverter module circuit; current transducer; overload; acceleration and deceleration time is too shortEtc.. Some models do not use OC to mark such faults. They are explained by load side short circuit, frequency converter overload, serious ground fault and so on. This is of course the alias of OC fault.
