Product Description:
The CSH01.3C-NN-EN1-EN2-CCD-NN-S-NN-FW is a plug-in control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It slides into compatible power sections to form a modular drive that interprets fieldbus data, processes feedback, and issues motion commands. Within an automation line, the unit serves as the real-time interface between higher-level PLC instructions and the physical servo axes, translating control data into precise electrical signals for velocity, torque, and position. Its modular format also separates control electronics from the power stage, which helps integrate the unit into multi-axis drive systems without changing the basic operating role of the controller.
The analog front end offers an input resistance of 160 kΩ, allowing connected sensors to interface without significant loading. Each conversion step is resolved to 1.23 mV/inc, while outgoing analog commands are generated at 19.5 mV/inc, supporting smooth reference changes during closed-loop operation. Digital inputs recognize an ON state at 15 V, and the sourcing digital outputs can deliver up to 500 mA to external relays or indicator lamps. Real-time communication is carried over the CCD Ethernet channel in compliance with IEEE 802.3, and the engineering port supports 100Base-TX for setup and service access. Feedback encoder channel EN1 supplies 8 V DC at 250 mA for HSF transducers, and the board can issue discrete gating signals with a minimum pulse width of 100 ms.
The controller power demand remains low, with logic and interface circuits drawing just 8.5 W from the drive’s auxiliary supply, although a startup inrush of 4 A must still be accommodated by upstream protection. Resolver-based feedback on EN1 is excited at 4 kHz and 18.2 Vpp AC to maintain stable position tracking during high-speed motion. Secondary encoder channel EN2 provides 5.0 V DC with a maximum current of 350 mA for TTL sensors, which allows the controller to support an additional feedback source alongside the primary channel. These electrical characteristics support stable signal handling across feedback, command, and interface functions inside the drive system.
