Product Description:
The CSB01.1C-SE-ENS-MEM-L2-S-NN-FW control section is a modular drive controller component from Bosch Rexroth Indramat within the CSB Drive Controllers series. It manages torque and position loops for IndraDrive power sections and coordinates motion over a SERCOS fieldbus network in automated machinery. By converting high-level PLC commands into precise control signals, the unit enables synchronized multi-axis servo operation on production lines, packaging equipment, and material-handling cells. As the command-processing portion of the drive, it sits between the machine control and the power electronics, interpreting axis commands and matching them to motor feedback data. This arrangement supports coordinated motion when several servo axes must follow a shared timing reference.
Real-time communication occurs over the SERCOS interface, and the channel is set for a data transmission rate of 16 MBaud, allowing deterministic exchange of setpoints and feedback. The current control loop is refreshed every 125 µs, so commanded torque changes propagate quickly to the motor windings. The unit provides 8 digital inputs for discrete command channels, while the single digital output can source up to 500 mA for actuator signaling. The digital I/O can be used for enable, interlock, or status-related signals within the drive system. Encoder feedback is accepted in IndraDyn, Hiperface, 1 Vpp sinusoidal, and TTL formats, and the card supplies 11.6 V DC at 300 mA for those transducers. Support for multiple feedback types helps the controller work with different motor feedback devices without a separate conversion module. The housing dimensions of 241 mm in height and 103 mm in depth fit standard IndraDrive cabinet slots, and the emulator connector supports cable lengths up to 40 m for remote setup.
The integrated safety channel provides Safe Torque Off (SIL3/Cat.3 PLe) so drive energy can be removed without auxiliary contactors. This safety function supports shutdown of torque production without removing control power from the entire cabinet. A 24 V, 1 A STO feedback contact handles acknowledgment, and a 24 V, 3 mA control input arms the safety logic. During power-up, the module draws an inrush of 4.5 A, and its signal emulator can reproduce encoder patterns at 1 MHz for downstream control testing. The housing is 49.5 mm wide, which permits side-by-side mounting with adequate airflow around the PCB.
