CSB02.1A-ET-EC-NN-L3-NN-NN-NW

The Bosch Rexroth Indramat CSB02.1A-ET-EC-NN-L3-NN-NN-NW from the CSB Drive Controllers series features a Multi-Ethernet Master Communication architecture and a Basic Scope interface equipment for robust industrial control. This CSB02.1A-ET-EC-NN-L3-NN-NN-NW unit incorporates an Encoder Option 1: Multi-Encoder Interface and explicitly states Encoder Option 2: Not an option, ensuring compatibility with a wide range of encoders. The single-axis control section supports up to 7 digital inputs and provides 2 optional slots for expansion modules. Safety is assured via integrated STO (Safe Torque Off) technology alongside Profibus communication.

Performance tuning is optimized through variable cycle times: velocity control from 125 to 250 µs, current control from 62.5 to 125 µs, and position control from 250 to 500 µs, with communication control windows spanning 250 to 500 µs depending on firmware version. The drive’s robust design includes an encoder evaluation module to maintain precision under dynamic loads. Single digital input and output channels can be arbitrarily configured, and a dedicated 10 V analog input supports fine-tuned feedback loops. Modular expansion via the two optional slots allows integration of fieldbus, IO-Link, or safety modules.

Physical dimensions of 103 mm (depth) x 49.5 mm (width) x 241 mm (height) make the controller suitable for high-density control cabinets. Supported firmware FWA-INDRV-MPx-18VRS or higher must be ordered separately to enable advanced functionality. Recommended wiring uses stranded conductors of 0.75–1.50 mm² for the 24 V voltage input. Wake Industrial offers a one-year replacement warranty to ensure minimal downtime and reliable operation throughout the product lifecycle.
