The west wanderer rst has been red-lighting to indicate a malfunctioning frequency. The reason why the jefroncivier was out of power two hours later and the transmission of the frequency was probably due to overpressure and stress, the westever was studying 22 failures, an alarm parameter check method: [example 1] the frequency malfunction, and led showed “uv” (depressed abbreviation)。
One, what's the code for the jefroncivier frequency changer
The output stream is too small. The default code “err. 30” represents an output current of less than “f8. 31” at the drop-detection level of the jefroncivier. The frequency transformer (variablefrequencydrive, vfd) is the electrical control device that controls the exchange of electrical motors by changing the frequency of the power source of the electrical power。
How do you install the westway frequency
(a) the west wing is a high-performance drive produced in italy, first applied in the country by the western u. S. Ocis, with unique advantages in matching the synchronized electric power: first, the driver has a rather rich pi that can be broken down into four segments (including a zero-speed pi) and is broad enough to allow non-loading signals to be applied when matching a carving power; second, there are two self-regulating procedures within it: the first is the self-regulating of the electrical parameters, which automatically fixes the inter-phase perception and resistance constant of the generator, and avoids the increased difficulty of debugging due to incomplete electrical parameters provided by the plant; the other is toothless positioning self-refining, which detects the position of the encoder and the electromagnetic pole。
Three, the west wrettard's current learning 22 failure
1 method of checking warning parameters: [example 1] a frequency variable malfunction, led showing “uv” (unpressed abbreviation). In the manual, the alarm was the dc carrier's stress. This is because the control circuit power is not taken from the dc matrix, but rather from the control power as a result of the flow of the exchange input through the transformer. So it should be true that the police were called. So starting with the power source, the power voltage is correct and the filter capacity is zero volts. Because the short-circuit contacts charged with resistance are not moving and are not connected to the whole stream bridge。
The charge resistance was detected with a universal meter after the power cuts. The replacement of the resistor will be repaired soon. 2. Comparability test method: this method may be either an analogy of the same circuit itself or of the failure plate and the known good plate. This can help maintenance staff rapidly narrow the scope of inspections. [for example, sanken's mf15 was damaged and returned for repair. Users are unclear about the situation. First, input ends r, s and t are measured using a universal scale. With the exception of some electrical resistance between r and t, other endpoints are infinity。
Four, the west wrett is always red
This indicates that the frequency transformer reported failure. When the signal alarm flashes above the liquid crystal display screen of the mutator, the action is performed immediately, first by pressing the shift key on the mutator panel, then by pressing the alarm key, indicating that the mutator is malfunctioning. At this point, alarmlist is seen on the lcd menu, where the line above the screen is alarmlist, the line below the screen is the fault code, the maintenance staff should record the contents shown in the next line, check in time for the frequency transformer-related failure code and perform a check-in on the corresponding failure。
Five. What's wrong with the jefroncivier
The most likely reason for the failure of the jevelenciveer was overpressure and stress. The peak of communication when the power was sent again caused excessive pressure damage to the transformer's power panels by the shock of the high voltage wave. If currents or voltage are increased to the non-quantified level of the varianter, the components of the equipment may be damaged, most commonly the transmission bridge. Normally, such damage will be caused by excessive heat generated by voltage or current peaks, and the use of fuses or circuit breakers will avoid the passing of electricity。
Six, west wing debugging
(a) the west wing debug i. The west wing is a high-performance drive produced in italy and first applied in the country by xiiko ocis, which has a unique advantage in matching the synchronized motor: the first of these drives is a highly functional pi that can be broken down into 4 segments (including a zero-speed pi) and is broad enough to allow for no loading of the signal when matching the carving machine, and there will be no slippage in the start; second, there are two self-regulating procedures within it: the first is the self-regulating of the electrical parameters, which automatically fixes the inter-phase perception and resistance constant of the generator, and avoids the increased difficulty of debugging due to incomplete electrical parameters provided by the plant; the other is toothless positioning self-refining, which detects the position of the encoder and the electromagnetic pole。
