There are some more infors I have just checked with the machine today. Hope any experts can advice me what to do and send me information if any.
Appreciate your help very much
1. On the assembly of the machine, I think we did all right every things.
2. I did check the cable and all cable connection, using voltage and Ampere devices, all seems OK.
3. The encoder signal errors are existed at all axis but not only Y-axis. I did change the encoder cable of axis on the driver, the errors are no change.
4. I did disconnect all the encoder cable (S,X,Y,Z and A) and found that Axis's drivers notified the start-up errors. It means that there's no problem with encoder.
5. I did check the power supply to machine using test device and it found that the power supply is fully enough but the 24V power supply to SIMODRIVER 611 was automatically lost (power off) after 1 minute power-up of the machine, leading to the power lost on Drivers ( I don't know the cause).
6. In conclusion, I think the errors roots from the source driver named SIMODRIVER 611. I am looking for any information, books related to SIMODRIVER 611 to find the cause.
7. I am sending here with some pics.
