I bought this machine a month ago as "broken" im almost done with my dynamate 4400 retrofit so i have been loking for a bigger machine.
The problem is that its stone dead on the drivers. It starts and do what it should do (im pressing CE and the memory reding works) until i press the yellow start button then it says -axis drive fault- no lamps on the Bosch drivers ligt up.
I have done som measuring but its quite hard following al the wires. the "hard" limit switch works (the e - stop ones) the air pressure switch works. i have oil in the lube system but i havent yet (but im going to) checked the oil level switch.
I Think i have found every fuse in the machine and al of them are ok.

Do anyone have something that could help me? i would like to get my hands on anyting showing the electrical system.?


The machine is well taken care of and has no wear at al (and i mean no wear) on the table. they have been using fixture and the cabinet has al the color left inside no scrathes at al just a dent on the cabinet.
My plan was to retrofit this machine but i want to run it first listening and get a feeling for the machine..
It is equiped with a 10 000 rpm spindle

My list of what i in the future want the machine to do is.
Run closed loop.
Ridgid tapping .
have 2 more axis to lift on to the table.
Easy loding of program.(dont want dropfeed or rs 232

Retrofit
Probably something else than the Ethernet smootstepper i run with mach 4 on my dyna. mach 4 is quite ok but with the ess i Think its a litle to much buggs in the system. Here i love to have your toughts of diffrent systems..

The projekt dont have a tight time scedule thoug i have my dynamate but im eager to get it running..

After reading quite lots of threads here i found a service bulletin poster by machinetech.
It stated that on the psu 1 and 2 the 24 volt 0 should be connected to earth.
The previus owner had change one psu. (The one for relay power) and probably not knowing this.
I dont know why it broked. But now the machine dont get the axis drive fault.
Here i hoped the story would end but when i power up and al relay get power the 24 volt that should run trough the relay drops to 0
Back on the horse. I now got 2 sheets of what i Think is the electrics for my machine and i Will try to backtrack.
Everyones thoughts is apriciated.
