Can someone give me some troubleshooting tips on a 1986 Anilam Crusader II control on a Lagun FTV-2 vertical mill? We just bought this for the iron, and planned to retrofit a new control, but this Crusader II powers up, reads the scales on each axis so we are seeing if we can bring it back to life and give it a try instead of jumping into the retrofit.

The Crusader will let me manually jog the servo motors if I hold in the reset button on the back of the Crusader II control system. If I do not use the override, there is no motion.

I pulled the boards from the controller and cleaned the edge connectors and reseated all the connectors and no change. I did not see and obviousliy blown componenets, but there were a few where heat had discolored the pcb under them.

I have a nice wiring diagram of the amp box from Anilam, and can see the function of the override is to override a loop that contains the estop button, limit switches and thermal overloads in the amp. Pushing the override button allows 24vdc in this loop to pass through some relays and power up the servo amps and finally reach ground according to the diagram. The diagram shows a transistor in the Crusader II normally doing this task, but the override is available apparently to test the system to see if you have other problems.

I decided to take a break and ask for help hoping someone will remember this problem. Next I was planning to trace through this amp enable loop and see how far the signal proceeds. My hunch is that the problem is in the Crusader control and it is not able to switch this transistor, and this would likely require replacement of one of the controller boards.

I'm sure some of you guys have solved this problem before, so thanks in advance for any advice you can give me.

Thanks,

Dear Members Sorry for the delay actually I am busy and little worryed about my CNC Crusader II Anilam fitted on KONDIA milling M/C not working Plz let me help either I will retrofit the other unit or repair it but I have no wiring diagrams of this if I switch to an other Controller any one could tell me which unit is most suitable to maximum utilizing the already available components with the old Controller. THANKS
