SCN5 power up, but not doing anything!!!

[toivonen]

Hi

I'm building motion simulators using SCN5/6 actuators, never had a problem, but now a SCN5 stop from working!...it turns on, but does nothing in terms of movement of the rod...i saw that a common problem was a broken pin, so i opened the actuator, but soon found out that in terms of structure everything was OK...so i've changed the PCB's (electronic controller) from one good SCN5 to the other, ans it started to work well...so my question is:

1- Is it the entire PCB that it's not working?

2- Is it something that happened and i have to reprogram it?...is it possible for me to do it?

3- I noticed that the rod is connected to a thin wheel that is activated by the PCB through a little laser light...can it be the source of the problem?

4- Also noticed the power cable was damaged, could that mean that the connector where is the ILK pin is dead?

4- If i can't repair it, what is the best way? Returned to Japan (it's already more than 5 years), to MiraiIntertech, to Frex?...is there someone here in Europe that could repair it? What would be the costs associated?

MANY THANKS
