I'm having an issue on a KRC4 that has been running for months, but now the customer (I'm not on site) can't get it to start up. Everything is fine, until it tries to go to a position, and causes a fault I've never seen an can't find a lot of info on.
The fault says "Block change on STOP". The pointer is on the first real motion point (the first point is PTP $POS_ACT, the first real motion is a linear movement). Instantly the drives turn off, and can not be started again until after the program is reset or canceled (according to the customer, not 100% sure on this, but I was on the phone with him when he was trying this). Having him reboot with reload files, so we'll see if that clears it up.
Any ideas what this fault is about? Especially on a system that has been running great for a few months.
Thanks
