Without seeing the schematics I would imagine that VCC is a supply for the logic that the machine must include. So I would say that it would need +5v give or take. Thats about the most common for logic circuits.
VCA could be the spanish equivalent of VAC which is AC input. The 220v requirement you could achieve with a simple power supply connected to the mains.
Is there anyway you could upload a useful part of the schematic so that suggestions can be more constructive?
I hope this has helped in some way.
