Product Description:

The CSH01.1C-SE-ENS-MA1-MD2-S2-S-NN-FW is a control section module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive power sections, it issues time-critical motion commands, processes sensor feedback, and handles fieldbus communication so multi-axis machines can run coordinated profiles in industrial automation lines. It supports both analog and digital I/O, allowing the connected drive to interact with external process signals. This arrangement lets one control section coordinate command handling, feedback evaluation, and signal exchange inside a compact drive platform.

This module provides 2 analog input channels and 2 analog output channels, each scaled to a ±10 V analog signal range, so velocity or torque references can be exchanged with external motion cards or process controllers without additional converters. Discrete control is handled by 16 digital input channels for status or limit switches and 16 digital output channels for interlocks, indicator lamps, or pneumatic solenoids. Two SERCOS ports operate on the SERCOS II protocol, allowing line or ring topologies with deterministic timing, and an integrated SSI evaluator reads absolute encoders directly. The encoder rail supplies 12 V to feedback devices, and the card tolerates inrush currents up to 4 A during power-up. The maximum output pulse width for each digital line is 100 ms, which helps protect connected relay loads during extended switching events.

The digital outputs can source up to 0.5 A digital output current per channel, enough to drive many contactor coils or optical isolators. Internal electronics dissipate a modest 7.5 W base power consumption, which simplifies cabinet heat planning and helps keep the surrounding drive assembly compact. Communication speed is capped by a 16 MBaud SERCOS rate, supporting fast cyclic data exchange for tightly timed motion control. The integrated safety architecture implements Safe Motion functions, and its dedicated relay path switches up to 1 A to remove drive power in hazardous situations. This gives the controller both motion-control capability and a direct role in monitored shutdown behavior.
