Q:What are the parameters of the frequency converter? Thank you: This function is to protect the motor overheating and set up, it is the frequency converter CPU, according to the operation current value and frequency to calculate the temperature rise of the motor, so as to overheat protection. This function is only suitable for "one on one" occasion, and when the "one is more than one", hot relays should be installed on each motor.Electronic thermal protection settings (%) n (A) / motor rated current rated inverter output current (A)] x 100%.

Q:How to deal with the fault Yaskawa inverter GF: See the Yaskawa inverter protection circuit structure, and the other is the same frequency. Over current OL1, OL2 and OL3 fault signals should be current transformers and subsequent current detection and processing circuits and CPUThe fault signals of GF (ground) and OC (load side short circuit) shall be fed directly to the protection circuit of the drive circuit board to feed the CPU. The difference is that at the initial stage of the start-up, the detection module is abnormal, i.e., a fault is reported.If the module is detected in operation, the OC fault is reported. These two kinds of signals, but also revealed such a message: the initial stage, it has not yet established the three-phase output voltage, the load is not running, the actual fault sources should be inverter driving circuit or the IGBT module itself caused by the abnormal, but does not rule out a ground fault load;In operation, there is a very large current, jump OC, the load side of the probability of failure is large, but also over current fault, rather than ground fault. The difference between GF and OC faults and what they mean is really reasonable.

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 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:I would like to ask, the inverter in use in the grid is very high?: In the process of using frequency converter, the demand for voltage fluctuation of power grid is not high. It depends on what brand of transducer. As a result, most of the grid voltage can meet the requirements, except in rural or remote areas where voltage changes exceed their permissible values. In addition, the frequency converter on the power grid harmonics also have requirements, if the harmonic content of more than 20%, will lead to frequency converter misoperation, false alarm, more serious circumstances, will lead to inverter out of control, or damage. However, most of the current harmonics will not happen, unless a large number of individual factories use frequency converters, servo, intermediate frequency furnace, welding machine and other equipment.

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's the use of switching frequency of converter?: Very important！The higher the switching frequency is, the smaller the harmonic is when the output waveform passes through the motor winding. The reason is that the higher the switching frequency is, the higher the harmonic frequency is, the higher the harmonic impedance is, and the smaller the harmonic current is. The smaller the harmonic current is, the smaller the harmonic loss is and the smaller the torque ripple is, the better the motor performance is.However, the higher the switching frequency, the greater the frequency converter loss, the lower the efficiency of the inverter, and more importantly, the greater the heat, the inverter may not be able to bear.In addition, according to the fundamental frequency of operation, the switching frequency is preferably an integer multiple of the fundamental frequency, and this multiple is an integer multiple of 3, which can effectively reduce the low harmonics which affect the motor greatly!

Q:What is the function of a frequency converter on an electric motor?: Mainly for AC motor speed regulation, but also is a smooth stepless speed regulation. You can also implement some specific controls.

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

Q:Can the motor with frequency converter directly wave the insulation?: The use of motor inverter drive, if the measurement will not disconnect the motor and inverter, tramegger issued a "high voltage" will spread through the winding inverter inside, will lead to some components breakdown within the inverter a damaged, because some components although the internal current is higher but the degree of pressure will be very limitedTherefore, in shaking the test of the use of inverter motor insulation, the inverter and motor connection is broken after the start, you can ensure that the frequency converter will not be damaged.
