Product Description:

The CSH01.1C-PB-ENS-EN2-NNN-L1-S-NN-FW control section is manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The unit slots into IndraDrive power bases and handles axis processing, encoder evaluation, and network messaging so that motion sequences in industrial automation stay synchronized with master PLC commands. Within a drive cabinet, it functions as the logic core, interpreting fieldbus telegrams, generating analog references, and gating transistor outputs that actuate safety relays, brakes, or sensors. This architecture separates communication and feedback handling from the power stage, helping the drive respond quickly to axis commands and machine interlocks.

During startup, the 24 V logic rail can draw an inrush of 4 A for no longer than 100 ms. After the surge, the unit consumes about 7.5 W to power its DSP, memory, and interface electronics. The same supply feeds the digital I/O block, which is permitted to source a continuous 1.1 A for field devices. When the eight high-side drivers switch loads, their combined current must stay below 1000 mA, and the energy returned by inductive coils must not exceed 400 mJ to avoid overstressing the clamp circuitry. The analog Output Type 2 channel uses an 8-bit converter to produce voltage references for proportional valves or speed trims, and the connected loads must remain within the available low-voltage limits.

Feedback and networking limits complement those electrical figures. The ENS encoder port presents a resistance of 120 Ω and supplies 11.6 V at 500 mA, while the secondary EN2 port provides 5.0 V at 350 mA for TTL encoders. Converted position words share the same 8-bit internal bus as the analog section, which helps keep latency low for closed-loop updates. For plant-wide communications, the module offers a PROFIBUS interface on a D-Sub 9-pin female connector that supports transfer speeds up to 12 MBaud. Separate encoder supply paths support different feedback devices, while the PROFIBUS link carries cyclic control and status data to the higher-level system.
