Product Description:

The CSH01.1C-PB-ENS-EN2-MD2-S2-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. As a drive controller module, it installs into an IndraDrive power stage and handles axis regulation, fieldbus traffic, and safety logic for industrial machinery. By integrating encoder processing, I/O expansion, and network links, the unit coordinates servo positioning tasks and synchronizes motion with upstream PLC sequences across automated production lines. This arrangement allows the control section to manage command processing and feedback handling within the same drive assembly, reducing the need for separate external control hardware.

For analog process signals, the board accepts an input span of ±10 V, allowing direct connection of velocity or torque references from external sources. It can source discrete loads through its digital outputs, with each channel delivering up to 0.5 A, which is suitable for driving contactors or indicator lamps without extra relays. Feedback resolution is maintained by two independent encoder ports: the first supports IndraDyn/HIPERFACE/1 Vpp/TTL formats at an internal supply of 11.6 VDC, while the second handles EnDat 2.1/1 Vpp/TTL devices powered at 5 VDC. Local machine interfacing is expanded by a 16 In / 16 Out extension, so limit switches and sensor groups can be wired directly to the control section. The dual feedback arrangement also supports applications that require separate handling of motor feedback and additional position-related signals inside the same axis assembly.

System-level integration is handled through the fieldbus master channel, which communicates as PROFIBUS-DP and lets the controller exchange setpoints and diagnostics with higher-level control architectures. Functional safety is embedded through the Safe Motion package that meets SIL2 / Cat. 3 PL d, enabling safe stop and limited speed functions without external safety relays. Cabinet layout is simplified because the module occupies only 241 × 49.5 × 103 mm, leaving more rail space for auxiliaries, and its onboard relay output is rated at 24 VDC, 1 A so pneumatic valves or brakes can be switched directly during controlled shutdowns. The compact format also helps when multiple axes must be installed side by side in a narrow control cabinet with short internal wiring paths.
