RAC2.1-250-380-AP0-W1

The RAC2.1-250-380-AP0-W1, from Bosch Rexroth Indramat, is a premium offering in the RAC Spindle Drive Controllers series. This high-performance AC main spindle drive controller delivers precise speed regulation and torque control, tailored for industrial automation needs. A compact, screw-in module form factor streamlines cabinet design, while its dual CAN channels support advanced network topologies. Purpose-built for demanding environments, it guarantees consistent spindle operation under varying loads.

Equipped as an AC Main Spindle Drive Controller, it accepts a 100-240 VAC Power Supply and draws just 14.5 W in standby to minimize heat dissipation. The unit features 2 CAN interfaces with full electrically isolated circuitry to prevent ground loops and EMI disturbances. Its versatile Network Capability and internal CANopen protocol enable real-time diagnostics, parameterization, and predictive maintenance. The screw-in installation reduces assembly time—note that the TB712 terminal block must be ordered separately—and the design functions seamlessly Without additional encoder input.

Integration is seamless: the RAC2.1-250-380-AP0-W1 fits directly into modular spindle systems and supports hot-swap replacement for minimal downtime. Robust electrical isolation and low power consumption cut heat load and enhance reliability in continuous-production settings. Ideal for turning centers, milling machines, and high-speed drilling spindles, it ensures dependable, high-precision performance in industrial automation applications.
