How the cycle voltage of wheel hub CNC lathe power supply voltage
Check the sequence of the method is very simple, one is measured with the phase sequence table, as shown in Figure 3-2a, when the phase sequence is correct when the phase sequence clockwise rotation, otherwise it is phase sequence error, Will R, S, T any two wires connected to adjust the position on the line. The other is to use two-wire oscilloscope to observe the waveform between the two phases, two phase phase difference in the phase 1200.
Verify that the DC power supply output is short to ground. A variety of CNC system has a DC power supply unit, for the system to provide the required +5 V, ± 15V, ± 24V and other DC voltage. Turn on the control cabinet power supply, check the output voltage.
Before the power is turned on, the motor power line can be disconnected first to ensure safety. In this way, the system will not cause small CNC lathe work. But should be based on the description of the repair instructions on the speed control unit to make some necessary settings, not due to disconnect the motor power line caused by the alarm. Turn on the control cabinet power, the first check the cabinet inside the fan
Whether it is rotating, which is to determine whether the power supply is the most convenient way. Then check the printed circuit board voltage is normal, all kinds of DC voltage is within the allowable range.
Confirmation of fluctuation range of power supply voltage. Check whether the user's power supply voltage fluctuation range is within the allowable range of the CNC system. General CNC system allows the voltage fluctuation range of 85 ~ 110% of the rated value,
Enter the confirmation of the supply voltage phase sequence. At present, the feed control unit of the CNC small CNC lathe and the power supply of the spindle control unit are mostly controlled by the crystal tube. If the phase sequence is not connected, the power supply of the feed control unit may be blown.
Fuse is the device "guardian", always protect the safety of equipment. In addition to the main line on the power supply fuse, almost every circuit board or circuit unit are equipped with fuses, when the overload, the external voltage is too high or the load side of an unexpected short circuit, the fuse can be immediately cut off and cut off the power, Protect the role of equipment, so be sure to check the quality of the fuse
Quantity and specifications are met.
