Hi. Me and my friend is trying to figure out whats wrong with his 3-Axis Cnc mill with Heidenhain Tnc155. The previous owner lost the battery power so my friend bought this machine not working, but the machineparameters are back where they belong now and this is the problem we have. We start the machine ( 400v three phase ) and the system starts up. Then the TNC says something in Swedish wich is hard for me to translate ( power off or something like that ) you clear it with CE. Then is says something like this, sorry if i´m translating wrong- The feed for the relay is missing. This is when you´re supposed to press Machine on. And this is where it stops. Nothing happens, i think we´ve checked almost everything. Looks like we have powersupply to all components, i have also measured the "power on" signal to the I/O board in the machine and it´s there. On my machine you can hear the contactor activating the servotransformator when pushing "machine on" but in this case.. Nothing .. All the fuses seems ok and the wiring looks ok.
The machine is a make: Modig and is Swedish
Anyone that can help in any way? Please =)
Thanks.
