Need Help!- INTERACT 308 TOOL CHANGE

[bertcnc]

Hi everyone,
1990 Bridgeport 308....
When I command a tool change the Z comes down to the correct height but the spindle does not orientate and the servos turn off.
An M19 orientates OK. The tool clamp / unclamp works but the magazine wont rotate or traverse.
Can anyone please help.
Where can I get bridgeport schematics or manuals?
Thanks

There were two versions of the DISCOVERY 308. The younger ones had SIEMENS drives, a BMDC board and a newer type mother board. I do NOT believe the 1990 version is considered the newer type so it has a FMDC and a Mentor spindle drive.
There are motors that turn the tool carousel and a cam for the in/out motion.
When homing, I believe the tool carousel should also home. If not I would be checking that circuit first. Any error messages coming up?
See if EBAY or machinemanuals.net has any manuals OF THE CORRECT generation for this machine.

Thanks for the reply. Mine has a Control Techniques v400 Flux vector ac spindle drive and the axis servos are Bosch.I got the Heidenhain parmater manual but I haven,t anything on the original PLC prog. The cnc is not signalling the relays which control the toolchanger motors on an M6 T*
Been trying everywhere for schematics with no luck--hope someone out there can help
Thanks again

My bad. I have no idea what is in your machine. Only worked on one INTERACT 308 many years ago and I have 27 years on Bridgeport machine service. No data either.
Try EMI.

I would 1st check the Air switch that moves the tool changer in & out from the tool. These go often.

I got a scanned copy of the schematics but because the originals were on A4 the copys are illegible.Yeovel Machine tools in the UK have an original manual ,perhaps they could let you try and copy it.Which spindle drive and distribution board does yous have?

In a tool change operation everything is done by M codes with verification.
So the initial condition must be verified that the machine is safe. This allows the tool change to begin.
Next it goes to a tool change height. This position is verified. Then it orients. This is verified. The tool changer goes forward, verified, it allows the tool to be unclamped, verified, etc........

Where it stops is where the problem is, possibly with verification.
