Product Description:
The CSH01.1C-ET-EN2-MEM-MA1-NN-S-NN-FW control section is manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive rack, it mediates between the drive’s power stage and external PLC commands, handling analog measurement, encoder feedback, and trajectory generation for servo axes used in pick-and-place stations, web tension systems, and other coordinated motion tasks. By hosting dedicated A/D and D/A converters alongside programmable encoder logic, it forms the real-time layer that closes current, speed, and position loops inside the automation cabinet. This arrangement lets the module process external analog references while also managing motor feedback on the same platform.
Two analog input paths provide an accuracy of ±0.3% at 90% of range across 2 differential channels, allowing precise voltage sensing for load cells or potentiometers. Each input accepts a span of ±10 VDC and is digitized at a 12-bit depth, matching the internal math resolution used by the IndraDrive controller. The board also offers two analog outputs for reference signal reproduction, and the specified minimum load must be maintained for linear operation. Encoder support covers 1 Vpp sine-cosine, EnDat 2.1, and 5 V-TTL formats, while incremental or SSI emulation can be generated for downstream devices. A dedicated supply delivers 5 VDC to power external transducers, and the analog outputs include current limiting to protect the converter stages.
The emulation port drives square-wave signals up to 1 MHz, which corresponds to the listed 1000 kHz limit, so high-resolution feedback can be duplicated across an application distance of 40 m with the specified coaxial cable. This allows the controller to mirror position information to counters, secondary displays, or auxiliary controls without disturbing the primary feedback path. Encoder excitation draws 350 mA when every channel is active, and the voltage outputs remain stable down to a 1 kΩ load. These limits support position cloning, analog process control, and synchronized multi-axis motion in industrial systems.
