Q: Surface grinder can add frequency converter, what are the advantages and disadvantages?: The use of variable frequency speed control, you can simplify the gear, gearbox and other complex mechanical drag mechanism, high degree of automation, simple operation, easy maintenance.The frequency converter adopts the external terminal control, and the DC 0-10V signal issued by the numerical control system is fed into the frequency converter through the VI ACM terminal of the frequency converter, and the digital setting speed is controlled to the analog variable frequency output. The motor speed is controlled by the size of the voltage signal produced by the numerical control system.The frequency converter has voltage (DC0 - 10V), current analog input interface, and can be well matched with the control signal of CNC system.

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): It is possible to control more than one motor with 1 inverters, which are controlled by the transmission track motors in general metallurgical projects, but should pay attention to the following points before operation:1 the choice of inverter power (the power converter must be greater than or equal to the sum of the motor power)2, the choice of control mode (usually with VF control, no speed feedback open-loop control)3 parameter settingsA sets the current value of the motor to the sum of the current values used by all motorsB sets the voltage and frequency of the motor, which is the voltage and frequency value of an electric motor

Q: What does 0L1 stand for?: Inverter 0L1 stands for frequency converter fault code: OL1: motor overload (OL1) fault for the output current exceeds the overload capacity of the motor, then need to reduce the load.

Q: It was when processing a workpiece, processing spindle stops suddenly (other are normal) a check is, I jump out of the inverter, I can click on a processing, and then processing not long after they happen, (do not open the machine spindle machining will also be the case): Has the frequency converter been used for a long time? The inverter power placed on the two day, and then open, put the line inside the head plug again, and then boot general can solve the problem, new don't try

Q: What is the working principle of elevator frequency converter?: The basic principle of VVVF elevatorAccording to the theory of motor, the speed formula of AC motor is:N=60f (1-s) /pUpper type: F is the stator frequency, and P is the pole count;S is slip; n is speed.

Q: How to deal with the fault Yaskawa inverter GF: This problem most likely. While G7 or F7 are generally Holzer Holzer sensor, sensor due to temperature. The influence of environmental factors such as humidity, work is easy to drift, to report "GF", another reason may be: E2-01 improper setting may also reported GF fault.

Q: How can I control the frequency converter with a computer?: The commonly used PLC and DCS control system in industrial area are applicable to the conditions of inverter interface control module, can realize the closed-loop converter convenient automatic control in the control system, widely used in large and medium. The control device for some smallexperimental device and embedded processor in inverter control, generally also need to deal with the keyboard input, display, data acquisition and other work such as process control, this control is more suitable for single-chip control system as the core, and uses PLC and operation panel, it can achieve the function but the cost is too high. Should not be used.

Q: Can 220V use frequency converter to drive three-phase motor with 380V?: If it is a star connection instead of a three phase 220V AC input, will the efficiency of the motor be reduced? Can you achieve the efficiency of the original motor 380V?

Q: Can the motor with frequency converter directly wave the insulation?: Is not possible because of the use of the insulating shake shake table while the output is DC but after conversion voltage value will exceed the rated voltage of the motor, the only way to test the motor winding phase to ground and insulation. But if the use of motor inverter drive, measurement of motor and inverter will not disconnect it, shake table issued a "high voltage" will be through the introduction of inverter winding inside, will lead to some components breakdown within the inverter a damaged, because although some internal components can be through the large current but the degree of pressure will be very limited so, in the insulating shake measure motor using frequency converter to the inverter and the motor is disconnected after, can make sure not to damage the transducer.

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?: Reasonable wiring: 1. principle - control line as far as possible from the input and output lines.2. non parallel principle - the control line should be crossed as far as possible in the space and the input and output lines, preferably the verticalStraight crossing, not parallel.3. phase principle - two control lines are adjacent to each other.
