XCS2-W0070ARN-02AX3T0ECET-S04RSN0NNNN0NN by Bosch Rexroth Indramat

The XCS2-W0070ARN-02AX3T0ECET-S04RSN0NNNN0NN is a high-performance single-axis converter engineered by Bosch Rexroth Indramat as part of the XCS Single Axis CtrlX Converters lineup. This generation-2 ctrlX DRIVE unit delivers a rated input current of 44.4 A and supports an output voltage range of AC 0 … 500 V and DC 280 … 710 V for versatile automation tasks. With a maximum DC bus power rating of 53 kW and an output current capability of AC 35 A, DC 38.2 A, it provides ample drive capacity for medium to heavy industrial motors. The converter weighs approximately 5.8 kg and occupies a compact frame of 309 mm × 196.5 mm × 100 mm, facilitating integration into standard control cabinets. It is designed to operate reliably across mains frequencies of 50 … 60 Hz and withstands short-circuit currents up to 42 000 A rms.

Technical capabilities are anchored by its integrated ctrlX CORE communication type and configurable protocol defined via ctrlX CORE apps (XCS2). The control hardware is based on ctrlX DRIVEplus, delivering precise motion control and seamless software updates. Connectivity options include a multi-encoder interface and multi-Ethernet support as hardware options, while the unit ships without a motor connector set for flexible field wiring. It features a maximum current rating of 70 A at the DC bus and incorporates an integrated braking transistor/braking resistor for dynamic braking. The converter’s robust design complies with export licensing requirements (no license needed for maximum output < 599 Hz) to simplify global deployment.

Operational features emphasize safety and reliability in industrial automation environments. The internal air cooling method ensures consistent thermal performance under continuous load. A built-in Safe Torque Off (STO) safety function provides immediate disabling of the drive output in emergency scenarios, complying with functional safety standards. The panel option includes an integrated control panel for straightforward parameterization and status monitoring. Recommended wire size of 6 AWG ensures secure power distribution and adherence to electrical codes.

Integration is further simplified by its slim device depth of 196.5 mm, allowing dense installation of multiple converters side by side. Its maximum DC bus power of 53 kW makes it ideal for driving a wide range of servo and induction motors in precision motion applications. With no additional design features required, the converter integrates seamlessly into existing ctrlX DRIVE ecosystems and third-party automation platforms. This versatile converter is particularly suited for machine tools, packaging machines, robotics, and general industrial automation environments where compactness, performance, and safety are paramount.
