The R911256095 (RAC 3.5-150-460-API-W1-220) is an AC main spindle drive controller manufactured by Bosch Rexroth, designed for applications requiring a 150 A current rating. It operates with a power input of 3 x AC 400 V ±15% or 3 x AC 460 V at 50–60 Hz and features control electronics powered by AC 230 V at 50–60 Hz. The unit provides an analogue speed command input of ±10 V and supports additional encoder input for spindle feedback, as well as an incremental encoder output for CNC position control. Cooling is handled by an internal blower. Mechanical accessories for mounting, including housing flanges and screws, are included. The device does not feature an additional bleeder and utilizes a high-resolution INDRAMAT encoder with an X4, 9-pole interface terminal.
