Product Description:

The CSH01.1C-ES-ENS-EN2-NN-S-NN-FW is a controller module in the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. It serves as the central motion processor inside IndraDrive systems, translating set-points from a higher-level PLC into real-time drive commands for servo and spindle axes used in packaging, printing, or handling equipment. The module also hosts the series’ encoder interfaces and communication ports so that position feedback and network telegrams reach the drive without external converters.

The base board draws 7.5 W, minimizing cabinet heat while still powering two analog outputs that can generate ±10 V reference signals for auxiliary actuators. Motion data is exchanged over Sercos II; a maximum channel speed of 16 MBaud and a minimum cyclic period of 1000 µs let the controller close position loops with millisecond latency. During initial energization the module momentarily demands 4 A of inrush current, a value relevant when sizing the 24 V supply. Axis feedback is accepted through an IndraDyn / HIPERFACE / 1Vss / TTL interface on connector X4 and a second port that supports EnDat 2.1, 1Vss, or TTL signals, eliminating separate option cards. For sensor rails the board can source up to 500 mA at the Ens output and accept incremental edges at 400 kHz without losing counts.

To close the feedback loop with absolute encoders, the secondary En2 channel senses 5.0 V on its supply pin, tolerates a load of 35 Ω, and can deliver up to 350 mA to the transducer. The Ens rail provides a higher voltage of 11.6 V DC so mixed-voltage sensors can be supported on the same axis. An isolated relay contact rated at 30 V DC, 1 A is available for brake release, ready-signal, or fault fan-out functions that must remain galvanically separated from logic electronics.
