Product Description:

The CSH01.1C-SE-ENS-ENS-NNN-S2-S-NN-FW is an axis controller module from Bosch Rexroth Indramat, included in the CSH Advanced Controllers series. Designed to slot into IndraDrive assemblies, this unit coordinates servo drives by exchanging real-time position, velocity, and safety data over the SERCOS motion bus. Within an automation cell, it serves as the central motion processor, linking encoder feedback to drive commands so that multi-axis machines maintain synchronized trajectories.

With dimensions of 241 x 103 x 49.5 mm, the controller fits shallow control cabinets, and its internal electronics draw only 7.5 W. During power on, the supply rails experience a surge of 4 A that lasts up to 100 ms, after which current settles to its operating level. One analog channel accepts differential signals in the range of ±10 V, and two independent outputs source commands from 0 to +5 V; these ports let the module supervise pressure or speed references without additional converters. Encoder sockets X4 and X8 follow the ENS pinout and provide 11.6 V DC for sensor excitation. The board recognizes IndraDyn S, HIPERFACE, EnDat 2.1, 1 Vpp, and 5 V-TTL formats, enabling mixed feedback topologies on a single axis.

The communication backbone is SERCOS, and the module sustains a network throughput of 16 MBaud so cycle times remain in the sub-millisecond range for coordinated motion. Eleven opto-isolated inputs and four sourcing outputs give the unit a discrete interface of 11 inputs / 4 outputs, which is suitable for limit switches, drive-ready signals, and interlocks. The encoder rail can supply up to 500 mA, allowing two high-resolution devices to run simultaneously without auxiliary power supplies. For risk-reduced applications, the built-in Safe Motion function is certified to SIL2 / Cat. 3 PL d, enabling safe stop and limited speed monitoring without external relays.
