Product Description:

The CSH01.1C-PB-EN2-NNN-NNN-S1-S-NN-FW is a compact control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive power module, it handles axis processing, fieldbus communication, and integrated safety so that drive-based motion can be synchronized with higher-level automation equipment. By combining bus interfaces, encoder evaluation, and modular option slots, the board coordinates position loops and diagnostic data without the need for an external PLC in many machine architectures. This arrangement allows one drive to manage motion commands, status exchange, and protective functions through a single control platform.

The controller draws a base consumption of 7.5 W and also powers installed option cards. The EN2 encoder board requires 6 W, the PB fieldbus board requires 2 W, and the S1 safety board requires 1 W. Communication with the machine network takes place over PROFIBUS-DP through an X30 D-Sub 9 Female connector, so cyclic setpoints and status words can be exchanged at rates up to 12 Mbit/s. For feedback, the unit provides an EnDat 2.1 interface through a D-Sub 15 female socket for bidirectional digital position data. An internal regulator supplies 5.0 VDC to the encoder, which helps isolate sensor power from external supply fluctuations. Safety I/O functions accept 24 V signals at 3 mA on dedicated terminals to trigger STO or related protective actions.

Runtime signaling also includes differential sine-cosine or TTL tracks at 1 Vpp, 5 V TTL. The encoder supply rail can deliver 350 mA, which supports high-resolution multi-turn encoders without an external booster. The safety module provides actuator control rated at 24 V / 0.5 A, allowing direct switching of contactors or valves during a fault response. Diagnostic and parameter access is available through the integrated service port that accepts a MiniDin 8 plug, and a maximum cable length of 15 m can be used without repeaters for service software connections.
