The R911256086 (RAC 3.5-100-460-API-Z1-220) is an AC main spindle drive controller engineered for control of 1MB frameless and main spindle motors with power outputs ranging from 10 to 30 kW. It supports a rated connection voltage of 3 x AC 400 V at 50 Hz (±15%) or 3 x AC 460 V, with a rated current of 100 A. The controller includes an internal blower for cooling, supporting air intake from either within or outside the control cabinet, and is designed to operate optimally at ambient temperatures up to 45°C with sealing to prevent condensation. It features an analog speed command interface (+/- 10 V), an additional encoder input for high-resolution spindle feedback, and provides an incremental encoder output. Control and configuration are managed via a panel, interfacing through a 9-pole X4 terminal. An additional bleeder is incorporated for enhanced power dissipation. All accessory modules and programming parameters are provided separately.
