Product Description:

The CSH01.1C-S3-ENS-EN1-MEM-NN-S-NN-FW control section is a modular controller module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It mounts into IndraDrive power sections and coordinates servo axes by executing motion commands, I/O handling, and fieldbus communication. Within an automation cell, this module translates high-level machine instructions into real-time drive signals, providing deterministic control over motor torque, speed, and position for packaging, printing, and material-handling equipment. It serves as the command-processing layer between the machine controller and the connected power section, handling time-critical control tasks inside the drive platform.

Its logic electronics run from a regulated 24 VDC control supply, so loss of cabinet control power disables command output and places drives in a safe state. Network integration occurs through the master interface SERCOS III, which supports cyclic data exchange below 1 ms and integrated real-time diagnostics. For position feedback processing, the board provides two selectable encoder channels. The primary socket accepts IndraDyn/Hiperface/1 Vpp/TTL transducers, while the secondary connector supports HSF/RSF formats, and both routes can be used for automatic axis identification and parameter download. The analog monitor port can source 5 V reference signals for scope verification of internal setpoints. Each encoder input is intended for a different feedback family, which broadens compatibility with motors already installed in the machine.

A resolver excitation carrier of 4 kHz is generated so legacy resolver feedback can be evaluated without external oscillators. The unit includes encoder emulation, allowing it to synthesize quadrature or sine-cosine signals for downstream devices that lack direct bus connectivity. It is not equipped with functional safety circuits, so emergency-stop functions must be handled by external safety relays or a separate safe-motion module. The housing measures 241 × 49.5 × 103 mm, which allows dense stacking of multiple control sections on a common backplane while still leaving airflow paths for drive cooling.
