This is a Centroid M400 AC-servo retrofit to a 1995 vertical machining center. The retrofit was completed in January 2009.
The machine has a 15HP AC spindle, two-range hydraulic gear shift
and 24-station random-access hydraulic tool changer.
The machine was originally equipped with a Mitsubishi Meldas control.
I installed a Centroid M400 control with 3kW AC servo motors, powered by high-power Centroid SD1 servo drives. A Centroid PLCIO2 unit provides the I/O interface for all machine accessories.
The control cabinet. Servo drives are in the upper left; Delta VFD-VE
spindle drive upper right; AC power switching and distribution across
the bottom; and PLC I/O and DC distribution on the door.
