Product Description:

The CSH01.1C-PB-ENS-EN2-MD2-L2-S-NN-FW is a plug-in control section developed by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive platforms, the board coordinates motion axes, handles fieldbus traffic, and provides local process I/O. In an automation cell, it acts as the interface between the drive power section and higher-level PLCs, converting system commands into precise torque or position instructions for servo motors.

Its analog interface accepts differential command signals up to ±10 V, while a dedicated channel can source control feedback at 5 V, 1 mA for trim pots, transducers, or reference outputs. Network communication occurs on the integrated fieldbus module, and telegrams move across the backplane at a bus rate of 12 MBaud, allowing synchronized updates to multiple drives. The same module supports standard DP addressing, so no external converter is required. Base electronics draw only 7.5 W, which simplifies cabinet thermal calculations and permits passive cooling in many applications. On the digital side, control words move through the fieldbus, freeing the local CPU for the motion kernel and diagnostics while preserving deterministic exchange on PROFIBUS.

Peripheral resources are distributed across three onboard daughter sections. The En2 encoder supply delivers 5.0 VDC with an available load of 350 mA, supporting high-resolution feedback devices without an external power rail. A second encoder channel, Ens, provides 11.6 VDC at 500 mA and accepts TTL input streams up to 400 kHz for rapid position capture. Discrete machine interface points are handled by the MD2 module, which offers 16 In / 16 Out transistor lines for limit switches, valves, and light curtains. Relay logic is minimized, yet a contact set rated at 24 VDC and 1 A remains for isolating critical alarms. Functional safety is implemented through the hardware-wired Safe Torque Off channel, which exits the board on a D-Sub 9-pin female connector. For absolute position devices, an SSI port using an RJ12 6-pin plug supports cable runs to 75 m.
