DYNA MYTE 4800 / MITSUBISHI MELDAS_500 ATC & SPINDLE problems

Hello,

I have a DYNA MYTE 4800 with MITSUBISHI MELDAS 500 control. I'm not sure, but I think that the model is old and discontinued. Well, I've two problems with this CNC:

1./ SPINDLE

In MDI mode I turn on the spindle and works ok, but when a change to HANDLE mode the spindle turns off right away. I not sure if that is a coding problem or wire connecting PCB problem (electronic issue).

2./ ATC-MAGAZINE

In MDI mode I enter the tool code for automatic change, for example, T10 M6, but the panel shows me this failure code:
'P290 IF SNT. ERROR'
