Product Description:

The CSH01.1C-S3-ENS-ENS-NNN-S2-S-NN-FW controller is supplied by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It serves as the control section for IndraDrive modular inverters and coordinates motion axes in industrial automation. By managing real-time fieldbus traffic and processing encoder feedback, the unit links drives, higher-level PLCs, and safety circuits in a compact format. Designed for multi-axis systems that demand deterministic communication, the module provides resources for speed, torque, and position loops while integrating safe stop and monitoring functions. It is intended for coordinated servo applications in automated equipment.

Communication with the drive bus occurs through Sercos III over a 100Base-TX link using RJ-45 8-pin ports. The electronics draw from a DC 24 V control supply, isolating logic power from mains drive sections. Two feedback inputs are present, and the device offers 2 encoder channels that accept IndraDyn, HIPERFACE, 1 Vss, or TTL signals. Each channel can source 500 mA at 11.6 V, allowing most incremental or absolute transducers to be powered directly without external conditioning. These electrical limits help keep signal levels stable during interpolation and support closed-loop accuracy at the network cycle time.

The logic section draws only 7.5 W at idle, yet it tolerates a startup surge of 4 A for a 100 ms inrush window, preventing supply drop while large drive capacitors charge. Safety is embedded at SIL2 / Cat. 3 PL d, and the integrated Safe Motion option allows velocity or position monitoring without extra relays. Cabinet layout is simplified by a footprint of 103 mm depth, 49.5 mm width, and 241 mm height, permitting dense stacking of multiple controllers on a DIN rail. The narrow housing helps conserve cabinet space when several coordinated axes are installed side by side.
