Hello guys,
I am new here but I read the forum for quite a long time.
Some time ago we have bought an used Daewoo Puma 2500sy from 2005 with Fanuc 18itb. Recently, we noticed that the main spindle clamp is not working.
After current measurements, we know that there is no 110v to solenoid coils out from the I/O module. The module (AOR16G) has been already exchanged, but nothing changed - the clamp is still not working.
After solenoid coils measurements, it looks that they are fine. The sub spindle clamp (M188/M189) works well.

What do You think about my issue? I am planing to exchange the AID module as well, but maybe some of You already had that (or similar) problem?
I think that it can be a signal issue, but the LEDS change when got the signal from the panel.

Thank You in advance for all suggestions.

Regards,
Arek
