Product Description:

The CSH01.1C-SE-ENS-EN2-EN2-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Housed in an IndraDrive rack, it functions as the motion and I/O processor that links servo power stages, feedback devices, and supervisory PLCs inside automated machinery. Its purpose is to convert field-level sensor data into deterministic drive commands while simultaneously exchanging cycle information over a real-time network. This arrangement lets one module coordinate motion tasks and local signal handling within the rack.

Two analog inputs tolerate a span of ±10 V; this range lets the controller read velocity or torque references coming from external sources. A high input impedance of 160 kΩ minimizes loading so transducers retain signal accuracy. When the application needs a reference out, an analog driver supplies 5 V, 1 mA for low-power devices such as potentiometers. Digital sensing points recognize a logic high at 24 V, 3 mA, and the paired transistor outputs switch up to 24 V, 0.5 A for contactors or indicator lamps. Communication with other drives is carried through a SERCOS optical ring, while a separate RS-232 port supports service diagnostics. The internal timing hardware can shape output pulses down to a 100 ms minimum width. A relay channel rated 24 V DC at 1 A provides galvanically isolated status signaling.

The enclosure measures 241 × 49.5 × 103 mm, allowing dense mounting in multi-axis cabinets without airflow restrictions. High-speed axis data moves across the SERCOS Interface, and the integrated Safety Technology I/O layer lets designers wire emergency stop chains directly to the card. At power-up, the section draws a peak of 4 A before settling to steady state. Encoder socket X4 sources 12 V for IndraDyn, HIPERFACE, 1 Vpp, or TTL feedback, while connectors X8 and X10 provide a 5 V rail for EnDat 2.1, 1 Vpp, or TTL protocols, ensuring compatibility with both incremental and absolute sensors. Separate feedback supply rails let the unit support multiple encoder families without external interface hardware.
