Servo Velocity Control Board SVC II – OKUMA 1006-0601 (2CH)

The 1006-0601 (2CH) is an electronic servo velocity control board (SVC II – “Servo Velocity Control II”) manufactured by OKUMA, documented as a component of the proprietary OSP (Open System Platform) CNC systems installed on OKUMA machining centres and lathes. The board implements the digital velocity controller for the machine’s servo axes, receiving velocity references from the CNC main CPU and closing the feedback loop via encoder or resolver signals mounted on the motors. Available in a dual-channel (2CH) variant, it is capable of managing two independent servo axes simultaneously on the same control backplane.

The SVC II board is the digital controller that closes the velocity loop on the machine’s servo axes: it interprets the velocity command issued by the OSP CNC CPU and generates the current reference to the drive power stage, keeping motor rotation stable and precise even under load variations. In case of failure, the control system loses velocity feedback on the affected axes, rendering the machine inoperable and triggering axis or drive alarms on the CNC panel.

OKUMA Corporation is a Japanese machine tool manufacturer founded in 1898 in Nagoya, among the world leaders in machining centres, lathes and grinding systems. A hallmark of OKUMA is complete vertical integration: machines, CNC controls (OSP – Open System Platform), drives and motors are all designed and manufactured in-house. The SVC II board belongs to the OSP5000/OSP7000 generations of the 1980s–90s and is legacy / discontinued: available only as used spare, surplus stock or through specialist repair.
