Our Mori MV 45 has been shutting off unexpectadly.
Any ideas ?
It is like someone pushes the off button on the operator panel.
This will happen if the machine is sitting idle or in a program.
Most of the time the machine will power back up by pushing the on button.
Sometimes the machine will stay on for 10+ hours at a time, other times it will shut off after 15 min. of on time.
The machine is a MV45 with a Yasnac MX1 control.
Mori says that the problem is on the Yasnac side, or a 24 volt short somewhere in the wiring.
Yasnac says that it is probably the 24 volt power supply.
My question is this, if it is the power supply, wouldn't just fail completly ? ( and not power back up ? )
Also what other possible problems could be causing this ?
I would like to look at all options before replacing a $1800 power supply.
