Check this.... 300200 Drive bus hardware fault Definitions: The drive bus has a fault. The following causes are possible: - The bus terminator is missing. - The drive bus is physically interrupted at some point. - Miscellaneous hardware fault. A check line is tested that runs over the entire bus and returns from the last rack location (bus terminator) back to the NCK. Note: If the drive ramps up correctly even though this message appeared, the error existed only at the beginning of the initialization. In spite of this, the drives can be capable of functioning Remedy: . - Check the bus terminator. - Check all plug connections from the drive bus to the drive modules. - Other hardware faults. Regards, Prakash

The X35 lights all went off and control booted up and estop would reset and all was ok. Now this morning the same thing has happened again! Is there anyway I can determine what is causing this? It sounds like a NC/plc problem or a faulty drive card maybe.

Do you still get the same alarm in the screen? Regards, Prakash

alexmac_uk Posts: 118 Rating: (1)	No I have no spare 611 cards to try this. I got it going again now but only by resetting plc again and reloading archive. Can I alter the plc startup time? Maybe this has something to do with it

alexmac_uk Posts: 118 Rating: (1)	There is no error message on screen now. But if I turn power off to the machine and then back on again anything after 30mins the fault comes back again!

There is a way to extinguishe the red led on the PLC side without actually clearing the PLC memory. Do you have and did you follow this sequence?

alexmac_uk Posts: 118 Rating: (1)	Hi, cheers for that. I have just reset NC and PLC like it says and loaded archives back in. Maybe the NC was corrupt. I have now turned machine off and will switch on again in 20 minutes. It's strange that if I switch off and on again in a short time period it boots up ok. It's only when it's left a while that the error comes up on start up!
