Product Description:

The CSB01.1C-SE-ENS-NNN-L1-S-NN-FW is a single-axis drive controller card manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. Installed in an IndraDrive modular rack, it supplies regulation and fieldbus connectivity for synchronous and asynchronous servo axes used in packaging, printing, and material-handling equipment. By combining motion control, field-oriented current loops, and integrated safety, the card coordinates torque, speed, and position feedback from external encoders so the parent automation system can synchronize multiple drives on the plant floor.

The controller regulates motor current every 125 µs, giving the drive the response time required for precise torque linearization. Command data enters through the SERCOS interface, and its inrush limiter constrains line surge to 4.5 A for no longer than 110 ms, which helps protect upstream circuit breakers. The card has 8 opto-isolated digital inputs, while three transistor digital outputs echo status bits and help streamline wiring inside the cabinet. The IndraDyn / Hiperface / 1 Vpp encoder port broadens feedback compatibility, so different motor families can share the same controller. Mechanical installation is simplified by the slim housing that occupies only 49.5 mm on the rail, with a depth of 103 mm that leaves clearance for airflow.

Once powered, the base board draws just 8 W, minimizing heat buildup and allowing dense stacking without active cooling. Communication through the RS232 serial port allows service access, and motion telegrams can be exchanged down to a 1000 µs SERCOS cycle for high-speed interpolation. An overall height of 241 mm aligns with standard 300 mm control enclosures, and the integrated starting lockout disables PWM until a validated 24 V DC / 1 A relay contact closes. The complementary 24 V, 3 mA start-lockout input accepts interlock chains or light curtain outputs.
