Hello guys

In our company we have an old Okuma twin spindle turning centre.Could anyone tell me, what this fault mean: alarm-a 1029-41 svp sa power circuit low voltage TA .
The book with alarm and error list explain the following: The servo amplifier has detected voltage drop in the amplifier power circuit. A warning lamp LV on the servo amplifier is lit
AXIS-in our case is TA turret , somtime is TB
We can produce pieces somtime eight houres or more, and than this alarm occur.
Is it posible that is temperature in back of electric closet is to high,or the problem is somewhere else.

And another problem i have in this machine that i cant turn turret with button in manual mode but in mdi or auto mode i can.

I would be happy for any help
