Solution: Combined with the SP1241 alarm cases that have been handled, it can be confirmed that the main cause of the alarm is the interference in the electrical cabinet. The main sources of interference are the internal power supply, transformers and various three-phase and single-phase coils. The wound components are JA40 analog output. Wire. The main reason for the analysis is that the analog voltage detection hardware is added to the 0iD motherboard, and the loop current is simultaneously detected when the 0-10V analog voltage is output. When the system is disturbed and the loop current exceeds the specified value, the detection circuit cuts off the analog output. , while triggering the system SP1241 alarm.
Therefore, the overall processing idea for SP1241 alarm should focus on the interference processing in the electrical cabinet. 1. Install an arc extinguisher on the three-phase and single-phase AC coils. The arc extinguisher can make it change smoothly when it encounters a large current, which can avoid interference and protect electronic components. 2. The transformer performs voltage conversion through coil induction, so it is a huge source of interference. The cables drawn from pins 5 and 7 of JA40 are too close to the transformer, which will induce electricity and cause the system to alarm. The transformer should be moved away from the system. , the machine tool is grounded separately.
