Product Description:

The CSH01.1C-SE-EN1-NNN-NNN-L1-S-K2-FW is a modular control section from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. Mounted on a compatible power section, the device acts as the central motion and communication layer, translating drive feedback and fieldbus data into coordinated axis commands for synchronized machine operation. In automated machine tools, packaging lines, and assembly cells, it supports closed-loop positioning through its resolver and HSF encoder interfaces while exchanging real-time setpoints with host PLCs over the SERCOS network. This arrangement lets the control section handle motion feedback and network communication within the same drive assembly.

Its internal electronics draw 7.5 W, minimizing heat buildup in compact cabinets. The analog interface presents 5 V reference signals at 1 mA, allowing speed or torque channels to be trimmed without external converters. On the binary side, each high-side transistor can switch loads up to 0.5 A, so status indicators or interposing relays can be driven directly. Servo feedback devices receive a stabilized 8 V supply through the HSF connector, and position data are processed against an 18.2 Vpp resolver carrier for consistent signal evaluation. With an overall width of 49.5 mm, multiple axes can be mounted side by side on a single rail while preserving a compact control cabinet layout.

The housing has a height of 241 mm and a depth of 103 mm, dimensions that help maintain cable bending radii in densely populated enclosures and leave room for adjacent modules. During power-up, the controller briefly draws 4 A of inrush current, a value that helps determine fuse selection and staged supply activation when several drives share one source. High-speed rotor feedback is accepted at a 4 kHz resolver carrier, supporting stable signal processing at elevated shaft speeds. The controller also includes a starting lockout safety option to support controlled machine behavior during enable sequences.
