Okuma SDU-600.W Arm Limit DC Spindle Drive System

Okuma SDU-600.W 3A-L Arm Limit DC Spindle Drive System is a DC spindle drive module designed for Okuma CNC machinery. The 3A-L designation identifies this as a specific variant within the SDU-600.W family. Described as an Arm Limit DC Spindle Drive, it forms part of the spindle drive hardware used in compatible Okuma configurations. It accepts a 200–230V 3-phase input at 50–60 Hz and draws up to 140 A, supporting the electrical demands of precision spindle operation. This drive system is intended to regulate spindle performance within the machine's control architecture, contributing to stable speed and torque management during machining cycles. Designed for integration within Okuma's tooling ecosystems, it aligns with standard electrical and control interfaces used in production environments.
