Q:Ask, what is the ratio of frequency converter?: Three inverter operation indicator light, the output frequency from 0.0Hz to potentiometer set frequency and the output frequency ratio is 1:1.5:2, adjust the tone potentiometer, change the motor speed and the speed of three units, according to the proportion of linkage. The output frequency of the three inverters can be adjusted with three Trimming Potentiometer respectively.

Q:I am in control of the equipment: the same mechanical movement, this needs a motor drive, a frequency converter drive. Now it's due to the mechanical location: buy two units of the same motor. Can you use a converter in parallel to drive it? Please point out! Thank you (frequency converter: the power of Schneider is equal to the sum of two motors): I suggest you use SIEMENS's 6SE70 model converter (I used this to do a lot of track debugging, it's really easy to use and not easy to go wrong)Communication with the PLC, as long as the Profeibus link on the good, communication and control characters are very good setRemark: a multi motor controlled by a transducer must start and stop at the same time, and the control speed is the same

Q:At the base block Yaskawa inverter is what reason?: This is the base block command, when the external input block command signal, the frequency converter will appear this code, the emergence of this code, the motor will rotate freely, does not affect the use.

Q:Can the frequency converter 7.5KW take the motor with 11KW?: No, in general, the selection of frequency converter is larger than that of motor, that is 11W frequency converter with 7.5KW motor.A motor with variable torque with a constant torque converter, which is permissible. But the load and the motor are constant torque, and the frequency converter is also constant torque, so doing is the small horse cart. Because the actual click can work continuously load is only 5.5kW, and then big, frequency converter can not stand.

Q:How does the PLC process the inverter output signal?: Frequency converter frequency signal will actually be converted to 4-20mA signal output, access to the PLC AI channel, SIEMENS 200 PLC, some CPU module comes with AI input, but also has a dedicated AI expansion module. What's left is software programming

Q:What are the differences between the two quadrant and the four quadrant of the inverter?: For a motor alone, the so-called four quadrant refers to its operating mechanical characteristics curve, on the mathematical axis of the four quadrants can run. The first quadrant is in the positive electric state, the second quadrant feedback braking state, the third quadrant reversing electric state, and the fourth quadrant reverse braking state. A frequency converter that makes the motor work in the four quadrant is called the four quadrant converter.

Q:What's the function of this brake unit?: The normal asynchronous motor in power loss, but also because of the inertia and load rotor rotate continuously for a period of time, at this time, due to the current of the rotor motor will still exist, such as the generator, sent to the power supply current. When a short circuit fault occurs, the motor also provides feedback current.

Q:A control panel I received a photoelectric switch, through the 232 interface connected to the computer, control with a 220V power supply board, computer and inverter when the inverter after the start of the photoelectric switch either do not work or turn off the flash chaos, frequency converter or 232 line open photoelectric switch will be back to normal work. In addition, when the photoelectric switch is powered separately, if the ground wire is connected to the control board, the photoelectric switch does not work. Excuse me, is this interference from the power cord? How to solve?: Reasonable wiring: the concrete method has:The power line and signal line of the equipment shall be as far as possible from the input and output lines of the converter.Other equipment power lines and signal lines should be avoided parallel with the input and output lines of the inverter.If the above measures are not successful, then continue the following measures:

Q:How much is the motor 90KW and the frequency converter selected?Colleagues suggest 110W?The cost will be higherIs it okay to choose 90KW?: Should be able to, in the design of the inverter in consideration of the corresponding motor power matching. Choose a large capacity, a little waste Oh! Our company choose frequency converter is one-to-one correspondence, did not choose the large capacity.

Q:What are the possible causes of frequency hopping overload?: The meaning of inverter overload protection is that the output current of the inverter continues to exceed the rated current, but it has not exceeded the transient flow point, and the general duration is defined as 1min. The general overload constant torque converter is 150% 1min, variable torque converter is generally 110%120%/1min.
