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

Q:At the base block Yaskawa inverter is what reason?: Garbage in Yaskawa signal board on the small line contact oxidation, look good, this is a kind of weak signal, and for safety relay is not the safety loop at high levels in a small line short circuit, 1000 Yaskawa A factory is shorted for a long time have blocked the oxidation base

Q:What role does input and output reactor play?: Enter the reactor to suppress the surge voltage and surge current protection, frequency converter, and prolong its service life and prevent the harmonic interference, at the same time as the speed control inverter adopts frequency conversion mode, so often produce harmonics and waveform distortion in the speed, will affect the normal use of equipment, therefore, should be installed in a line choke the input end of the inverter can improve the power factor and harmonic current suppression filter, harmonic voltage and harmonic current, improve the quality of power grid.

Q:What does Ro1c mean on a converter?: RO1C is the common terminal and the RO1A is normally closed, and the RO1B is normally open. The set of contacts is the output signal that is ready to run. That is, the self-test of the converter is completed and the output signal of the relay can be operated.

Q:How can I control the frequency converter with a computer?: Variable frequency speed control has been applied in the industrial field as the main means of AC motor speed control is very extensive, it has a wide speed range, steady speed and high precision fast dynamic response for a wide range of technical performance and reliable operation, has gradually replaced the DC motor speed control system. There are three main control modes of inverter: 1. through inverter panel operation, that is through the operation panel to change the output frequency and other operating parameters; 2. in the frequency converter analog input 0 ~ 10V or 4 ~ 20mA signal, by changing the size of input analog control of inverter output frequency converter; 3. through communication port (for RS485 control). The first method is generally used for manual adjustment and parameter setting on the spot, and the latter two are mostly used for automatic adjustment and remote control.

Q:Heating inverter commissioning steps: The no-load connection test of the frequency converter will connect the grounding terminal of the frequency converter to the ground 1. 2 the power input terminal of the frequency converter is connected to the power supply through the leakage protection switch. 3 check the frequency converter display window factory display is normal, if not correct, should reset, or request exchange. 4 familiar with the operation key of frequency converter. The inverter has run in general (RUN) and stop (STOP), programming (PROG), P (DATAPENTER), the data confirm the increased (UP, 3), reduce (DOWN, 6) and other key definitions of different inverter operation keys are basically the same. In addition, some inverters also monitor (MONITORPDISPLAY), reset (RESET), inch movement (JOG), shift (SHIFT) and other functional keys.

Q:The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?: The power over voltage means that the DC bus voltage exceeds the rated value because the voltage of the supply is too high. Now, most inverters have an input voltage of up to 460V, so the overvoltage caused by power supply is extremely rare. The main issue discussed in this paper is the regenerative overvoltage. The regenerative overvoltage mainly has the following reasons: when the big GD2 (flywheel moment) load slows down, the inverter deceleration time is set too short;

Q:Is the voltage low? The younger brother is bored to death, no problem with the wire drawing machine, the full load will jump off. Display frequency converter overload and acceleration operation overcurrent. Help me please.: There are only three reasons for the POFF fault: (1) the DC bus voltage detected by the machine is seriously low. (2) lack of phase signal. (3) the voltage level parameter of 220V machine is wrong. [method] use the shift key on the keyboard or the mask to switch the display content to the display bus voltage status.

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:How does the PLC process the inverter output signal?: Depends on analog or switch volume, if it is analog, you can use analog input module, if it is the amount of switching, with ordinary IO on it
