Product Description:

The CSH01.1C-SE-ENS-EN1-NNN-S1-S-NN-FW is a single-axis motion and safety controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. In an automation cell, this unit processes feedback from multiple encoder types and issues time-critical drive commands, enabling synchronous operation of servo axes linked over a fiber-optic ring. By coordinating position loops and managing integrated safety inputs, the device serves as the central drive control card inside an IndraDrive modular converter stack.

Drive communication uses the real-time bus protocol SERCOS II, ensuring deterministic telegram exchange between the controller and connected inverters. This allows the drive section to receive motion data in a predictable cycle during synchronized axis operation. For high-resolution position capture, the first encoder channel accepts incremental or absolute signals up to 500 kHz. This cutoff is the maximum edge rate the counter can track without loss. That channel supplies the sensor with 11.6 VDC and can source 500 mA, so shielded cable runs remain powered even at long distances. Setup computers connect through the Ethernet-based engineering link, specified as 100Base-TX. This interface supports parameter access over standard TCP/IP tools. A legacy diagnostic port is available, and its asynchronous line operates up to 115 kBaud, allowing simple ASCII commands or bootloader access when higher-level networks are unavailable.

The secondary feedback input works with resolver or HSF transducers, giving the controller flexibility when different motor feedback devices are used on the same platform. It energizes HSF sensors at 8 VDC and 250 mA, while a separate excitation of 18.2 Vpp at 4 kHz drives resolver windings for noise-immune shaft angle detection. Safety Technology I/O is integrated, and the board therefore expects a logic supply of 24 VDC. Its solid-state outputs can switch field devices that draw up to 0.5 A during emergency-stop or guard-door routines. The control section combines fast drive coordination, redundant encoder monitoring, and category-oriented stop functions without external modules.
