Product Description:
The CSB01.1C-S3-ENS-EN1-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSB Drive Controllers series. This plug-in card forms the command layer of an IndraDrive amplifier, translating motion commands into precise current and velocity references for a connected servo axis. Because it serves as the supervisory electronics for the amplifier, it coordinates command processing, feedback handling, and safety-related signal exchange inside the drive. It is intended for cabinet-mounted automation equipment such as packaging lines, pick-and-place gantries, and printing presses, where deterministic communication and integrated safety functions help keep cycle times short and machine states predictable.
The control board is configured for Single-Axis operation, so all current, position, and safety calculations are devoted to one motor. Motion data reaches the unit through a Sercos III bus that uses an integrated RJ-45 8-pin port, and telegrams are exchanged over the 100Base-TX physical layer. Once a command is received, the digital signal processor refreshes its current loop every 125 µs, which allows tight torque control even on low-inertia servo drives. Feedback from the machine side is read on Encoder 1, whose IndraDyn, Hiperface, 1 Vpp, and TTL formats share a 15-pin EN1 connector. A dedicated RS-232 service port is also available for setup and diagnostics when local access to parameters or status data is needed.
Safety-related requirements are handled through the integrated Safe Torque Off function, which is wired through a D-Sub 9-pin female connector on the front edge of the card. Encoder 1 supplies sensors with 11.6 V DC at up to 300 mA, while the HSF port sources 8 V DC for high-speed feedback chips. On the auxiliary channel, the board supports Resolver and HSF feedback; it excites the resolver winding with a carrier at 4 kHz and measures the 18.2 Vpp return signal to calculate shaft position. The separation of safety, primary feedback, auxiliary feedback, and service connections helps keep front-edge wiring organized inside the control cabinet.
