Product Description:
The CSH01.1C-S3-ENS-NNN-NNN-NN-S-NP-FW control section is built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It is inserted into an IndraDrive power unit to supply drive-level logic, fieldbus handling, and real-time axis regulation within industrial automation cells. By combining motion computation, local I/O scanning, and network communication, the module lets machine builders synchronize servo drives, coordinate auxiliary sensors, and pass status data to supervisory controllers. It also places command processing close to the drive hardware, which supports responsive axis control during rapidly changing operating conditions.
The two differential analog inputs accept a full-scale range of ±10 V, allowing the board to process velocity or torque commands without external scaling. Their input resistance is 160 kOhm, so signal sources see minimal loading and maintain accuracy over long cable runs. Each conversion step is 1.23 mV/inc, providing fine resolution for tight loop tuning. Fieldbus traffic reaches the section through a RJ-45 (8-pin) connector that carries deterministic Ethernet packets. Those packets conform to SERCOS III, enabling cycle-synchronous communication between multiple drives and the central PLC. Four configurable digital I/O points can be mapped as fast system triggers, while seven dedicated inputs reduce the PLC workload for tasks such as overtravel or door interlocks. Two probe inputs are reserved for position-capture events, and TTL lines can be driven up to 400 kHz to record high-speed sensor edges.
On the output side, the module delivers an analog reference of 5 V into loads down to 5 kOhm, with each increment equal to 19.5 mV/inc for consistent scaling across connected drives. Digital power stages may draw up to 500 mA from the sourcing outputs to actuate contactors or relays. Encoder feedback is cabled through a D-Sub 15 interface, and the input amplifier preserves signal integrity up to 500 kHz while the 11.6 V sensor supply supports differential encoder operation. This arrangement supports accurate feedback transfer and allows the control section to work with high-speed position signals without requiring separate external interface hardware.
