Product Description:

The CSH01.1C-ET-ENS-EN2-MEM-S2-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed on an IndraDrive platform, it provides real-time axis control by combining encoder feedback, fieldbus data, and integrated safety functions. In automated assembly lines, packaging equipment, and handling robots, the board executes position loops, velocity loops, and safety monitoring so that connected servo motors follow programmed trajectories with the repeatability required in industrial automation.

During operation, the controller draws a baseline of 7.5 W, which simplifies thermal budgeting inside compact cabinets. At power-up, the supply must tolerate an inrush of 4 A. Motion commands and diagnostics reach the unit through Multi-Ethernet; its physical transport is 100Base-TX, enabling deterministic 100 Mbit/s traffic for synchronous drives. A service port offers asynchronous communication up to 115 kBaud on RS-232 for service access. Two separate encoder inputs are available: Interface 1 supports IndraDyn, Hiperface, and 1 Vpp signals, while Interface 2 accepts EnDat 2.1, 1 Vpp, or 5 V TTL feedback. Absolute position data can also be delivered over an SSI output, so the available feedback formats match a wide range of servo motors and external controllers.

Safety and secondary feedback resources are also included. The integrated Safe Motion technology uses a dedicated safe I/O rail that is energized from DC 24 V and can source 0.5 A to external sensors. For simulated feedback, the board generates position pulses at 1 MHz and can switch between absolute or incremental emulation modes, while the native absolute output format is SSI. The EN2 encoder supply delivers 350 mA at 5.0 V DC and supports remote transducers mounted up to 75 m from the cabinet, helping maintain stable signal levels over long cable runs.
