Q:What is the frequency converter through function?: 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.

Q:Not to say that the inverter speed is mainly down frequency, how can I see the frequency rise to 60HZ, so that the three-phase motor is not more than the rated speed?: Frequency rising problem of frequency converter;Voltage matching; the rated voltage of the converter is in line with the rated voltage of the load.Current matching; ordinary centrifugal pump, the rated current of the converter is in line with the rated current of the motor. For special loads, such as deep water pumps, it is necessary to refer to the motor performance parameters and determine the current and overload capacity of the inverter with maximum current.Torque matching; this situation may occur when a constant torque load or a deceleration device.

Q:Can a power converter be used in a motor with small power? Will it burn the motor?: Large power converter can be used in small power motors, as long as the motor nameplate parameters, in the inverter motor parameters can be set, so that the inverter can provide the right protection.And。 Selection of frequency converter capacity, generally greater than the power of the motor more than one file.

Q:5.5KW frequency converter with 4.5KW deep water pump, pressure regulator by conveying signal to frequency converter start normal, the pressure to reduce the frequency converter after the start, to about 30Hz in order to maintain the pressure about shocks, 30 seconds inverter over-current alarm. Can it be the fault of the frequency converter? How should I check it?: UndervoltageThere is a problem with the power input circuit. It may be caused by serious overloading of the line or bad contact with the line. The letter "E" PMU display panel LCD screen SIEMENS 6SE70 series inverter, the inverter can not work, press the P button and to stop transmission are invalid, check the operation manual and the related introduction, in the external DC24V power supply, that is low voltage, solution, inverter working.

Q:What is the TTK converter produced?: Mainly engaged in TTK brand inverter products R & D, manufacturing, SMT surface mount OEM processing, and agents of well-known brands at home and abroad, frequency converters and electronic components. The agent of many brands, manufacturers become the primary agent, after ten years of unremitting efforts, has formed the electronic components supply system, to meet the basic needs of all customers required inverter suction electronic components. Due to the rapid delivery, excellent reputation, has a large number of customers in East China. Now the Shanghai Volkswagen Schneider, L.D., and many domestic large enterprises supporting inverter and electronic components products supply, for many years by the number of units as the best supplier.

Q:What are the contents of frequency converter maintenance?: Operators must be familiar with the basic principles of inverter, functional features, with basic knowledge of electrical operations. Before checking and maintaining the frequency converter, the total power supply of the equipment must be cut off, and the inverter Chang lamp will be completely extinguished.

Q:1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?: When we design the frequency converter to drag the motor load (mostly fan and water pump general machine), we should use shielded cable. We refer to the GB/T21209-2007 "inverter power supply design and performance of cage induction motors in section 9.1.4" guide "motor power cable" 9.1.4.1 "recommended configuration" in the "provisions of more than 30kW motor wiring should adopt the single core power cable or a plurality of grounding wire arranged symmetrical cable. Small power and suitable for wiring, priority is to use multi-core shielded cable." As the PE line symmetrical configuration of the 3+3 inverter dedicated cable, construction is always raised, not wiring, we later too lazy to explain, usually directly with the 3+1 type multi-core shielded cable. From the running situation, the effect is also good.

Q:Delta inverter fault output which parameter is set?: Overcurrent fault overcurrent fault can be divided into acceleration, deceleration and constant current. It may be due to the deceleration time is too short, the inverter load mutation, uneven load distribution, cause the output short circuit and so on. At this time can be extended through the deceleration time, and reduce the load of the braking element, mutation, plus load distribution for design, check on the line. If you disconnect the load converter or overcurrent fault, that inverter inverter circuit has ring, need to replace the frequency converter.

Q:How do you set the frequency with panels?. What are the specific steps?: The parameter 700 is the starting signal, the 1 is a panel key starting, and the 2 is an external signal starting;The parameter 1000 is the frequency setting value, and the 1 is a panel lifting key, and the frequency is changed, and 2 is changed by the external analog signal.Your problem, the start signal is set up, finished, the parameter 1000 should be 1, so that the panel set frequency, and then set the parameter 1031 to 1, so that it automatically save the frequency changes after the value

Q:It was when processing a workpiece, processing spindle stops suddenly (other are normal) a check is, I jump out of the inverter, I can click on a processing, and then processing not long after they happen, (do not open the machine spindle machining will also be the case): It should be a frequency converter. Right now, look at the frequency converter output frequency settings, tune, and suggest the next election wide output frequency converter, or simply PLC
