RAC 3.5-200-460-APD-Z1-220

The Bosch Rexroth Indramat RAC 3.5-200-460-APD-Z1-220 is a high-performance member of the RAC Spindle Drive Controllers series designed for precise spindle speed and position control in demanding industrial environments. This device features a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V and a robust Rated Current of 200 A, ensuring the capacity to drive heavy loads with consistent power delivery. As an AC Main Spindle Drive Controller, it delivers reliable torque regulation for machining centers, lathes, and milling applications, enabling accurate and repeatable operations.

Equipped with a dedicated Rated Connection for Control Electronics of AC 230 V / 50-60 Hz, the RAC 3.5-200-460-APD-Z1-220 supports an Analogue (+/- 10 V) speed command input and a Digital position set-point (16 bit parallel) interface for fine-grained control. The controller also offers an Additional encoder input for spindle feedback and integrates a High-resolution INDRAMAT encoder, enhancing feedback precision for responsive speed adjustments. An X4, 9 poles interface terminal simplifies wiring, while the inclusion of an Additional bleeder streamlines energy dissipation. Effective heat management is provided by an Internal Blower / Built-in fan, maintaining optimal operating temperatures under continuous duty.

Designed for seamless integration, this spindle drive controller ensures compatibility with standard industrial control voltages and feedback devices. The internal blower prevents overheating, enhancing durability and operational uptime. The high-resolution encoder and digital position interface guarantee precise synchronization with CNC systems, improving machining quality and reducing cycle times. With its combination of analogue and digital control options, robust current handling, and efficient cooling, the RAC 3.5-200-460-APD-Z1-220 offers a versatile solution for high-speed spindle applications, delivering enhanced productivity, reliability, and energy efficiency in advanced manufacturing processes.
