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:What does 0L1 stand for?: Overload is excessive load, more than the equipment itself rated load, the phenomenon is that the current is too large, electrical equipment heating, long-term overload of the line will reduce the insulation level of the line, and even burned equipment or lines.

Q:Ask, what is the ratio of frequency converter?: Rotating main potentiometer, respectively, to see the three frequency converter F1.00 parameters, keyboard digital display reference input, follow potentiometer changes, and the proportion of 1:1.5:2. Rotate three trimmer potentiometers respectively, and the reference input of the corresponding converter has little change.

Q:At the base block Yaskawa inverter is what reason?: For example: when you put the inverter to stop, there will be a signal to the inverter, then the converter will base the blockade, cut off the output, the motor will no longer work; when you need a converter work, there will be a signal to the inverter, inverter will cancel the locks on the base, and the normal work,This function is only equivalent to one protection.

Q:There is a feed and send system. Now due to the severity of the material is not the same as the two converters often change speed, the workers do not understand their own, often by, often bad now how to use the best way you can use a potentiometer or other method, control of the two frequency converter, synchronous operation. Is to adjust one, and the other also with the kind of frequency, so that you can let the workers themselves to open, and the two inverters, the same manufacturer, the same model, the same load,: What kind of communication mode does the frequency converter support? Generally speaking, it is more accurate to communicate by means of synchronization. Expensive。The main transformer potentiometer, from the analog frequency converter, may be 1, the lag will be greater than 2, analog may have a larger error, 3, analog may be subject to interference. The cheapest。You can also use synchronous controller, analog input, the two roads as the same analog, cheaper, more reliable synchronization, may be disturbed.

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?: Solution of interference caused by inductive coupling:The control circuit using shielding line, when connected to the control line and the inverter, the shielding layer can not only be grounded, one end connected to the transducer signal terminal can pay attention to public, regardless of whether the public or end shield grounding, only in the end, and can not be connected at both ends.

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.: When detecting the phase - lacking circuit, the phase - blank board is directly tested, and the PL signal on the drive board is normal. Normally, the PL is low, the phase is Fang Bo, and the power is high when the power is switched off. It is important to note that the PL signal output by the drive board or the phase blank panel is not sent to the CPU after the level switch has been passed on the main control board, and it should be noted that the fault is caused by the main board or the missing phase board during maintenance.

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:What are the precautions for frequency converter wiring installation?: First understand the instructions, do not take the control line wrong, power line into the wire outlet is connected, you can debug it

Q:How do you understand the ramp up (descent) time of the inverter? Thank you!: The reverse is the drop time, or the 0 speed. Water pumps and fan motors are basically not required to change. If it is an emergency stop, it is usually 3 seconds (depending on the frequency converter and process requirements).
