Product Description:
The CSB01.1C-SE-ENS-MA1-L1-S-NN-FW is a control section built by Bosch Rexroth Indramat for the CSB Drive Controllers series. Installed in a multi-axis cabinet rack, it serves as the command layer between a higher-level PLC and the power inverter that drives a servo or induction motor. By combining fast analog I/O, fiber-optic motion bus links, and an integrated safety channel, the unit coordinates position, speed, and stop functions used in packaging stations, material-handling lines, and other automated cells.
This section provides 2 differential analog input channels with 12-bit conversion so the drive can follow external speed or torque commands with fine granularity. Each input accepts a symmetrical 10 V bipolar signal, allowing positive and negative references around the zero point. Two analog outputs are also available, and they can source up to 10 mA for status feedback to external indicators or controllers. Feedback from the motor is read through the ENS encoder interface, and the card delivers up to 300 mA to power the transducer. Supported encoder types include IndraDyn, Hiperface, EnDat, 1 Vpp, and 5 V TTL formats, which allows the control section to work with several common motor feedback systems.
The encoder supply line is held at 11.6 VDC, providing stable excitation across the cabinet temperature range. Motion commands arrive over SERCOS, and Fiber Optic cabling is used as the transmission medium to electrically isolate individual axes and reduce ground-loop interference. A ready relay rated for 24 V DC at 1 A signals the controller’s operating state to interlocks. The safety option enables a starting lockout, and emergency deceleration follows the drive’s Category 0 stop profile. This arrangement supports coordinated shutdown behavior while keeping the safety and motion functions within the same control section.
