Product Description:

The CSH01.1C-ET-EN2-ENS-EN1-S1-S-NN-FW is a modular control section supplied by Bosch Rexroth Indramat for use in the CSH Advanced Controllers series. Designed as a plug-in unit for IndraDrive power modules, it performs servo-axis calculations, network communication, and local safety monitoring in industrial automation cells. By combining high-speed Ethernet communication with incremental and absolute encoder feedback, the hardware supports deterministic position control and real-time I/O processing for packaging, printing, and general motion applications.

The module draws a base power of 7.5 W, so cabinet thermal planning can usually rely on convection alone. Its digital input block accepts signals at 24 V / 3 mA, while the corresponding transistor outputs can switch up to 24 V / 0.5 A to operate contactors or indicator lamps. Two analog channels are provided, and each channel can source 1 mA or output 5 V for speed- or torque-related setpoints. For higher loads, the board carries an internal relay rated at DC 24 V / 1 A. Field communication is handled through Multi-Ethernet hardware over a copper link classified as 100Base-TX. When the application needs timed pulse trains, the controller can generate pulse widths up to 100 ms without measurable jitter. A front-mounted standard operator panel provides local access to status information and parameter editing.

Feedback handling is divided across three sensor ports. The primary interface accepts EnDat 2.1 / 1 Vpp / 5 V TTL, covering both serial absolute and analog incremental encoders, while a secondary socket works with IndraDyn / HIPERFACE® / 1 Vpp devices and a tertiary channel supports HSF or resolver signals for legacy axes. For host diagnostics, the board also provides an RS232 service connection when Ethernet is unavailable. Integrated Safety Technology I/O supports STO and safe-limited-speed functions without external relays, and the typical inrush current of 4 A is relevant for startup fuse sizing.
