Product Description:
The CSH01.1C-SE-ENS-EN2-MA1-L1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed for integration in drive cabinets, this module issues motion commands, processes feedback, and exchanges data with higher-level automation systems. Its role inside an industrial cell is to synchronize axes, manage safety interlocks, and relay real-time status to supervisory control software. It serves as the logic and interface layer between the machine control and the connected drive hardware, keeping signal handling and axis coordination in one cabinet-mounted unit.
Primary communication occurs over SERCOS II, a deterministic bus that uses fiber-optic cables to support high-speed cyclic data exchange with servo inverters. For local diagnostics, the front panel offers a single-line display, so basic status information can be checked directly on the unit. Position feedback devices powered from the ENS rail receive 12 V. The digital interface side includes one L1 control input rated at 24 V / 3 mA that can enable or inhibit the drive. The MA1 option block provides two differential analog inputs with 12-bit resolution, allowing fine command scaling. Two analog outputs deliver control references up to ±10 V; each channel can source 10 mA and drive loads down to 1 kΩ. These analog channels let the controller exchange reference and monitoring signals with external process devices without requiring a separate interface module.
The RS232 service port supports data rates up to 115 kBaud for setup and diagnostics. That port provides direct serial access when the field bus is not used for local service tasks. Encoder channels that require lower excitation can draw 5 V directly from the EN2 supply without external regulators. Output signaling to interposing contactors is handled by an L1 relay contact that switches up to 24 V / 1 A. The relay output passes a switched signal to external control hardware such as interposing contactors. When an emergency stop is triggered, the starting lockout follows the safety logic of Stop Category 0, which removes power without controlled deceleration.
