Product Description:

The CSB01.1C-ET-ENS-NNN-L2-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. Installed in an IndraDrive modular rack, it directs torque, speed, and position loops for servo or induction motors that power pick-and-place arms, packaging stations, and conveyor modules. By combining signal processing with fieldbus communication on one card, it supplies the real-time motion commands required for industrial automation while the associated power stage handles current delivery. In this arrangement, the control section interprets command data from the automation system and coordinates motor behavior at the rack level, while the separate power stage supplies the electrical output required by the motor.

It manages a single mechanical axis, so the control section handles 1 channel for interpolation and safety calculations. Network traffic is carried over the Multi-Ethernet interface, which accepts PROFINET, EtherNet/IP, and Sercos telegrams without hardware changes. Feedback flexibility is broad because the encoder port recognizes IndraDyn, Hiperface, 1 Vpp, and 5 V TTL signals, allowing support for both motor feedback devices and external encoders. Drive energy is removed on demand by the certified Safe Torque Off function. Machine-specific parameters are stored on a removable MultiMediaCard, and a vacant expansion slot is available for additional functions that fit within the same control-section footprint.

Command signals and machine states are processed locally because the controller offers integrated digital I/O and a relay output for contactors or brakes. This local interface allows the unit to exchange status information and simple control signals directly with nearby machine hardware. Service access is available through the RS232 port when Ethernet is unavailable, which supports direct local communication with the unit. When higher-level feedback replication or analog measurement is needed, an add-on board can introduce encoder, analog I/O, or encoder emulation capability while remaining inside the original slot envelope. User interaction is handled by a standard operator panel that provides parameter scrolling, status LEDs, and basic jog keys without an external HMI.
