I made a fool of myself

The drive speed of the paper machine controlled by frequency conversion was unstable; the production team asked me to replace the encoder, but I acted presumptuously by disabling that encoder within the frequency converter. It feels okay to use, but the production process remains unstable; unfortunately, I had to replace the encoder. Yet it seems like there’s no difference compared to before – the production issue still persists. You say whether it’s very embarrassing.
It can only be said that it has nothing to do with the equipment, but rather with people’s psychology
Yeah, there’s no way to explain such things clearly; it’s frustrating
Such things happen often. When I was working in plastic pelletizing, every time I switched to raw materials from different manufacturers, although I would conduct pilot tests and determine whether there were any differences in the quality of the pellets, the subsequent production units would report that the plastic pellets were unstable and had poor performance. As a result, the pellets had to be returned, stored for a few days, and then sent back to the production units for use – with no problems at all. It’s caused by psychological issues
What does a variable-frequency control paper machine mean? . . . . . . . .
It’s the same everywhere; production is handled in this way, with various excuses used to delay things and cut corners on quality.
A paper machine with variable frequency control is one in which a PLC communicates with the frequency converter via a bus to control a series of motors; the speeds of all these motors are interrelated, allowing them to operate in coordination with each other.
Hehe, that’s quite normal; when there are problems, different departments start arguing with each other. The corporate motto I saw in a company’s workshop during my last visit was: Don’t look for excuses to avoid problems; find ways to solve them. I think if the original poster has time, they should spend some time at the workshop site, communicate and discuss more with the operators on site, and work together to identify and solve the problem.
What was said upstairs makes sense – we should pay more attention to the production process in order to avoid unnecessary detours
It’s very profound. But at its core, it’s still a communication issue. It is necessary to pay attention to customer needs
