Product Description:
The CSH01.1C-SE-ENS-EN2-MA1-L2-S-NN-FW is a control section from the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. Designed as a scalable motion-logic processor for drive stacks, it interfaces directly with servo amplifiers and field-level devices to coordinate axis movement, analog process values, and discrete safety functions in industrial automation cells. It is typically mounted on drive controller racks within printing, packaging, and general handling machinery. This arrangement places command processing and signal exchange close to the drive hardware it supervises.
It draws only 7.5 W of base power at idle, which helps minimize cabinet heat load. Communication with the drive bus occurs over SERCOS II at rates up to 16 MBaud, allowing deterministic transfer of setpoints and feedback between the control section and connected drives. The first encoder port supplies 500 mA from an isolated source rated at 11.6 V, enough for high-resolution SinCos or TTL sensors, while the second port can deliver 350 mA and supports EnDat 2.1, 1 Vpp, or 5 V-TTL signals for feedback devices that need a lower supply voltage. Two differential analog inputs on the MA1 option card accept ±10 V process signals, and two analog outputs with the same span can command external actuators or exchange analog reference values with adjacent equipment.
The remaining interfaces support feedback, signaling, and service connections. The second encoder supply is stabilized at 5.0 V to match most absolute feedback transducers. The MA1 card has 12-bit resolution, allowing fine process adjustment without external scaling and giving the analog channels consistent granularity. A relay contact rated for 24 V DC / 1 A provides galvanically isolated signaling to interlock devices or drive contactors. The built-in Safe Torque Off function removes drive energy without disabling the logic section. For maintenance consoles, the RS-232 diagnostic port supports cable lengths up to 15 m, and the supported bus rate allows stable diagnostic communication across that distance.
