Hi , I have a Bridgeport BPC 320H with Fanuc 6MB11. I'm getting the alarm 2013 Magazine Servo unit alarm..It works fine on machine switch on first thing then after I run a few parts I get the alarm..if I reset the alarm with the power stop button I can re home the machine and re home the magazine no problem..
I'm getting the red PAL (position alarm?) light coming on at the A20B-0010-0100/02B board which seems to work the magazine servo drive.
The alarm appears if I try to manually index the magazine and when it tries to index the magazine during a tool change...the servo drive drops the enable light but no alarm lights on the servo drive..the other servo drives stay enabled and I can mpg the machine on all axis after pressing reset on the control panel(alarm lamp stays on). Could it be the Fanuc Multipole resolver on the motor..does the machine ignore the resolver when it homes the carousel as it only needs the home prox sensor for location? Then for a tool change it looks at the resolver for each tool position...?
It seems that because the magazine servo is not set as an axis I can't check it's diagnostics.
The motor is a Fanuc DC yellow cap 5M with 5x resolver and tacho.
I have no info on the A20B-0010-0100/02B board in my Bridgeport manuals..and nothing comes up on Google.
Many thanks in advance
John
