I am running 410shII with matrix control. I have started getting the 128 outside interlock alarm when the b axis needs to index, and on tool changes. It doesnt happen every time, and it is doing it on mazatrol program and eia programs. I'm just wondering if anyone else has seen this and if anyone knows of a cure. I can manually turn the b axis and program restart, and it runs fine, and will even turn the b axis to do tool changes and things without stopping but will eventually stop for the same thing later in the program. I think it is related to the locking and unlocking of the b axis, but i have never had to address this on mazatrol programs before. Thanks for any help.
