- 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)
- In theory, there is no problem with your use. If you have a good mechanical connection, you can do it. If you need high-precision association control, you need to use two inverters
- 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: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: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:How to maintain the frequency converter will not damage, or regular maintenance?
- 1. cooling fan, inverter power module is the most serious heating device, the continuous heat generated by the work must be promptly discharged, the general fan life of about 10Kh-40Kh. According to the continuous operation of converter for 2-3 years, it is necessary to replace the fan2. filter capacitor, intermediate circuit filter capacitor: also called electrolytic capacitor, its main function is to smooth the DC voltage, absorb the low-frequency harmonic in dc.
- Q:Why does the frequency change when the frequency converter regulates the frequency?
- Because the product of three-phase asynchronous motor stator phase voltage and frequency and flux is proportional to the frequency when the downward adjustment, if the sustain voltage is constant, the flux must be increased, this will cause the main magnetic saturation excitation current passing, the surge in motor damage.As a result, the voltage is usually adjusted down proportionally as the frequency is lowered down.However, when adjusting the frequency, the voltage is not adjustable in order to avoid the excessive voltage damage of the motor. Therefore, in the use of frequency converter overclocking motor, the magnetic flux will decline, the motor output torque characteristics will move to the left.
