Q:What is the difference between frequency converter and servo driver?: The difference between servomotor and frequency conversion motor:Servo system is a closed-loop control system, the inverter usually works in open-loop control, so in terms of speed and accuracy, and can not be compared to the servo drive.The frequency conversion is only one part of the servo, and the servo controls the closed loop precisely on the basis of frequency conversion so as to achieve better results.

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:What role does input and output reactor play?: The input reactor is mainly used to restrain the interference of the higher harmonic produced by the converter to the power supply and other equipments. The output reactor is mainly used to restrain the damage of the higher harmonic caused by the converter.

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 key points of frequency converter maintenance?: Frequency converter daily patrolDo the inverter daily inspection and inspection work, inspection contents mainly include: ambient temperature, humidity is required, ventilation windows is good; the inverter air inlet and outlet is blocked by dust or too much dust; inverter operation parameter is normal, there is no alarm; cabinet fan the operation is normal; if there is abnormal sound or vibration transducer; capacitor whether overheat.

Q:What are the benefits of installing economizer in industrial enterprises?: Frequency converter is a device that regulates the speed of an electric motor by adjusting the output frequency:1. The frequency converter can only reduce the motor speed by reducing the power supply frequency. The application environment is limited and the automatic control function is not available. It can not be used in many load changing occasions;Have a lot of 2 odd harmonics, frequency converter operation, it will seriously affect other equipment life and efficiency, at the same time use but also affect other precision control of the equipment in the factory, such as computer, automatic control system, monitoring system and so on;3 、 frequency converter serial access to the customer's low-voltage power system, the power supply of the customer security risks.

Q:Which country invented the inverter?: The frequency converter is not developed by a certain individual, it is the research result of a large number of scientific research workers.The background of inverter technology is the wide demand of AC motor stepless speed regulation. The traditional DC speed regulation technology is limited because of its large size and high failure rate.

Q:Heating inverter commissioning steps: And carry on the test run 1. manual operation of the frequency converter panel running stop, observe the motor running process and the frequency converter display window, to see if there is abnormal phenomenon. 2. if the P is started and the over-current protection is stopped in the motor, the acceleration P deceleration time should be reset. The acceleration of the motor during acceleration and deceleration depends on the acceleration torque, while the frequency change rate of the inverter during the start and braking is set by the user. If the inertia of motor or motor load change, speed or deceleration rate according to frequency change preset when possible acceleration torque is not enough, resulting in motor stall, motor speed and the inverter output frequency coordination, thus causing overcurrent or overvoltage. Therefore, it is necessary to set acceleration and deceleration time according to the inertia and load of the motor, so that the frequency change rate of the converter can be coordinated with the speed change rate of the motor.

Q:Schneider 303 4KW frequency converter F 013 trouble shooting method: You see when the alarm is started, or stable operation alarm amount, different times, different analysis

Q:Where is the frequency converter used?: From the industry application: 1, chemical, petroleum, electric power, municipal, mining, cement, water treatment and other industries, the main use of 380V/690V/6-10kv inverter, these industries have a large fan pump power, the original AC operation, high energy consumption, the use of inverter speed regulation can be obtained after large energy saving, so it is the the main users of the main high power converter
