Hi,
i have robot from this thread: TPU contact lost
After almost 2 years of welding i have problem that i haven't seen before and cant find the tips about it.
Since friday, after power on, sometimes i have fault TPU contact lost and sometimes it is hangs up on information Welcome in the S4 controller (which indicates no contact between TPU and CPU (?)).
It is strange, because I disconnect batteries and I can install new system without problems (arcware, parameters, program) - everythings work - UNTIL I power off and power on again - hangs up.
What i checked:
- Connection of TP - cables, plugs - OK
- replaced main CPU DSQC325 - no changes (I can install the system, later hangs up)
- replaced axis CPU DSQC326 (I put eeprom from my dsqc326, because i have only one pair of them) - no changes (I can install the system, later hangs up)
- batteries are both 3,62V
- replaced memory DSQC 321 - no changes (I can install the system, later hangs up)
Interestingly, i can do a P-start, or system restart from File menu without problems. I can't just power off.
Now I'm waiting for the new EEPROMS to check out.
Thank You for your help.
