Product Description:

The CSH01.1C-PB-EN2-EN2-MA1-S2-S-NN-FW control section belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. Installed in IndraDrive modular drive systems, it manages axis motion, fieldbus communication, and safety monitoring within a compact control platform. As an automation controller, it receives encoder feedback, processes application code, and sends setpoints to the connected power stage for coordinated positioning in packaging, printing, and material-handling equipment. Its role is focused on motion control, signal handling, and communication rather than direct power conversion. This arrangement lets the control section work with a separate power stage while keeping axis control and monitoring functions in one module.

Analog processing uses a resolution of 12 bit, enabling 4096 discrete values on each of the two differential input paths and the two voltage outputs. The control electronics draw only 7.5 W in standby, which helps limit heat inside the cabinet when the servo system is idle. Field-level communication runs at 12 MBaud over the PROFIBUS DP port, allowing real-time exchange of setpoints and status data with a PLC on a twisted-pair network. The encoder connector provides 5.0 V reference power and supports EnDat 2.1, 1 Vpp, and 5 V TTL feedback, with enough current available for typical linear and multi-turn sensors. The combination of differential analog channels, fieldbus communication, and encoder support allows one unit to handle reference signals and closed-loop feedback at the same time.

A typical inrush current of 4 A reduces startup stress on the control backplane and supports use with common 24 V supplies. Command handling includes 2 analog input channels, a matching pair of analog outputs, and an RS232 service port that accepts cable lengths up to 15 m for local diagnostics. The integrated Safe Motion function monitors encoder signals internally so the drive can perform controlled stop or limited-speed operation without an external relay circuit. Pulse-train capture up to 100 ms and dual encoder channels are also available, which helps the controller support feedback evaluation and service access in a single unit. The RS232 connection is intended for local service access, while the dual encoder capability supports applications that need motor feedback and an additional measurement source.
