RAC 2.3-200-460-A0S-W1

RAC 2.3-200-460-A0S-W1, Bosch Rexroth Indramat, RAC Spindle Drive Controllers: This spindle drive controller delivers precision and robustness for demanding main spindle applications. It features an onboard analog ±10 V Speed Command and dedicated Interface Terminal X4, 9 poles to simplify wiring. Designed as a modular controller, it supports fault elimination and diagnostics through an internal programming module. Its compact footprint integrates a built-in fan and heatsink housing for efficient thermal management.

As an AC Main Spindle Drive Controller, the unit accepts a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, ±15% or 3 x AC 460 V and provides a continuous Rated Current of 200 A. Cooling is handled by an Internal Blower / Built-in fan, eliminating the need for external chillers. Connectivity includes a Serial interface RS 232-C for parameterization and monitoring, while it ships Without additional bleeder and Without additional encoder input to match diverse motor feedback options. This is Series 2, Version 3, ensuring maturity and field-proven reliability.

Engineers will appreciate seamless cabinet integration via standardized terminals and the simple Analogue (+/−10 V) speed setpoint that pairs readily with PLCs and motion controllers. The robust forced-air cooling and absence of auxiliary bleeder circuits reduce maintenance intervals, enhancing uptime. Ideal for high-precision machining spindles, the RAC 2.3-200-460-A0S-W1 combines straightforward installation with dependable performance under industrial conditions.
