Problem error message 008 P/S on Fanuc 0-MF controller

Have an old Leadwell MCV-760AP with Fanuc 0MF controller, after the local Fanuc repair service provider repaired and re installed a new power-supply to the machine the error message 008 P/S appears quite frequently under program run in auto mode, this happens regardless the use of M99, M01, M30 in the program, it also appears if we run the machine in 25% or below on the rapid override button (G00), the machine does not move if low feed value (G01) is programmed.

all parameters are written back to the nc and the macro program 9001 and 9003 for ATC is also written back in the machine memory

Anyone?

Thanks in advance
