Engraving machine use frequency converter to set parameters and troubleshooting?

Carved on the use of frequency converter is mostly special inverter, its output frequency is 300 hz and 400 hz, machining center machines and even reached the high frequency of 800 hz, rated frequency is generally based on spindle motor factory parameters to set. Set the right frequency can make the spindle play better features, otherwise it will damage the spindle. Parameter adjustment, the first to set frequency, including the maximum frequency and maximum frequency, rated frequency, frequency of minimum. Maximum frequency is the highest speed corresponding frequency spindle motor, spindle motor rated frequency, rated frequency is also rated voltage corresponding to the frequency. Upper limit frequency is generally use at ordinary times, minimum frequency is lower. Frequency setting is not correct, spindle motor cannot work normally, for a long time can damage the spindle, which might damage the inverter. In adjusting frequency, also have to consider what is the output signal control system, generally have low high and analog section number to control the frequency of the spindle. If it is more than control section number, the custom is first three terminals for low and middle terminals, general factory defaults to 1, 2, 3, and then set the number of multistage frequency values, generally is 100 hz, 150 hz, 200 hz, 250 hz 300 hz350hz 400 hz several speed can switch back and forth, if it is analog control, the only change 10 v corresponding frequency, the maximum set to use at ordinary times frequency. These basic parameters set can normal use, but some special spindle, special models need to change other parameters, such as constant power spindle parameters setting, constant power spindle frequency range is wide, if according to the common curve set parameters, the spindle in the early stages of the start, there is a lot of noise, and the harm of main shaft is larger, by this time have to custom curve of frequency, is in a certain voltage, corresponding to a certain frequency, gradually will increase the frequency of the main shaft to best. Some models need to quickly stop the spindle, external braking resistance, need to open the inverter parameters of braking, and parking mode and stop and dc brake instead, parking will shorten the time, to meet the requirements of the scene. Frequency converter in the process of daily use, the most common fault is the police. We want to deal with the alarm problem, first of all have to find the directions, view explain what is meant by the alarm code. Common code alarm function: 1, under-voltage alarm refers to the input voltage is too low, is also likely to lack of phase, check whether the input voltage is abnormal / 2, through the pressure overload alarm, it generally refers to the frequency converter to use after a long time, generally have a power loss, this time will appear on the several kinds of alarm. Processing, reduce workload, not so deep before under the knife, changing parameters at the same time improve the inverter through the load range. 3, module fault, this is typically the output side has a short circuit or ground, then don't forced frequent access to electricity, so as not to damage the inverter, need to do is to check whether the converter UVW three-phase short-circuit, spindle motor is lighter plug phenomenon. After power on the inverter sometimes can't display properly, will have to check whether the inverter panel is installed, whether three-phase electricity into the inverter RST terminals, whether to have lighter smoking phenomenon, according to the phenomenon can find root cause, and prompt inverter for a long time need not, electricity when not to electricity, several times to frequent electricity blackout, so that you can avoid switching power supply and the damage of the capacitance.
