The Bosch Rexroth motor drive controller, MPN R911245503 (RAC 4.1-300-460-API-W1), is an AC main spindle drive controller designed for precise position and speed control in automated applications. It supports rated connection voltage of 3 x AC 400 V, 50 Hz, ±15% or 3 x AC 460 V and operates at a rated current of 300 A. The device incorporates an analogue speed command input of ±10 V and offers encoder connectivity through a high-resolution INDRAMAT encoder and additional encoder input for spindle feedback. Cooling is achieved with an internal blower and integrated ventilation components, with heat dissipation managed via air slits and a heat sink. The controller is intended for operation in environments with an optimum temperature of 40°C and requires a dry, dust-free storage condition. Connectivity is provided via a 9-pole X4 interface terminal, and the device features an incremental encoder output.
