Product Description:

The CSH01.1C-SE-ENS-NNN-MD2-S1-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Housed inside an IndraDrive assembly, it interprets encoder feedback and issues motion commands that synchronize axes in machine tools, packaging lines, and handling systems. By combining network communication, position processing, and local I/O, the unit forms the central control layer of a modular drive stack and converts SERCOS II telegrams into torque, velocity, or position references. This arrangement allows one module to manage feedback handling and command processing within the same drive platform.

Its analog circuitry supports high-resolution sensing and actuation. Source impedance is 160 kΩ, so external sensors are not heavily loaded, and each least significant bit on the input side corresponds to 1.23 mV/inc. Output channels provide command voltages with a step size of 19.5 mV/inc, allowing fine adjustment of drive current loops. Base power dissipation is only 7.5 W, which helps reduce thermal stress inside the enclosure. Absolute position data can be received through the SSI interface, while continuous control communication relies on the SERCOS II ring. This combination supports closed-loop motion tasks that require both steady feedback processing and reliable signal exchange between connected devices.

Network throughput reaches 16 MBaud, supporting short update cycles in multi-axis systems. The MD2 expansion adds sixteen digital inputs and sixteen transistor outputs, and each output can switch loads up to 500 mA without external relays. Attached encoders draw power from the integrated supply at 11.6 V, with a combined current allowance of 500 mA. A soft-start circuit caps startup demand to 4 A and limits the surge to 100 ms, which helps protect upstream fuses and power supplies. For functional safety tasks, the Safety Technology I/O option is present, and a dedicated rail supports light curtains, gate switches, or emergency stop chains. These features make the control section suitable for drive systems that need local signal handling together with coordinated networked motion control.
