The R911256141 (RAC 2.3-200-460-AP0-W1) is a modular AC main spindle drive controller engineered for precise low-speed motor regulation. Designed for direct connection to three-phase supply networks (3 x AC 400 V, 50 Hz, ±15% or 3 x AC 460 V), it integrates a DC braking mechanism for controlled spindle stopping during power loss. The unit features an additional encoder input compatible with high-resolution Indramat encoders for secondary spindle feedback and an analog ±10 V speed set-point interface suitable for CNC systems. With an internal fan for thermal management, the device supports a rated current of 200 A and utilizes a 9-pole X4 interface terminal. Operation at maximum permissible temperature (55°C) reduces rated data to 80%. Installation below 1000 m requires avoidance of condensed water, and a grounding connection is necessary for motor connectivity. The controller is rated IP10 and does not support external bleeders or additional interface modules. The programming module is located at the bottom of the device.
