According to the electrical schematic, this signal is derived from the intermediate frequency power supply. According to this clue, the intermediate frequency power supply part is inspected and found that the HS light on the control board sKI is not lit, and the HS light indicates that the machine part is ready and can be quenched. Check the input terminal of the control panel, SKI does not get this signal, the generation of this signal, Kl is the machine part preparation relay, measuring K1 coil no voltage signal, continue to measure and find that K20O contact is not closed, relay KZOO is subject to PLC Output AZ. There is no problem, and the coil of the measuring relay K20O also has a 24v voltage signal, then the relay K200 is definitely damaged. The coil of the K200 is measured, and the coil is found to be blown. After replacing a new relay, the fault is eliminated. 24V was overhauled before the transformation, and the mechanical precision was restored to the factory precision.
Using NuM's MMIT00I software, we have compiled our own graphical interface according to the characteristics of the machine. The operator does not need to program. Just fill in the appropriate data according to the workpiece material and processing requirements in the corresponding page form. In the software design, the algorithm for eliminating the accumulation of the tooth error is adopted, and the non-contact method is adopted for the position detection of the grinding wheel.
During commissioning, it is found that the direct output dynamic range from the analog port of the numerical control system can not meet the control accuracy requirements of the electro-hydraulic proportional servo valve, and the PLC segmentation control is used to control the high-precision continuously adjustable signal source. Prevent loss of control or damage to expensive servo valves.
