Product Description:

The CSH01.1C-SE-EN1-EN2-MA1-NN-S-NN-FW control section is built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on a Rexroth drive rack, it serves as the central motion processor that links fieldbus commands with power modules and motor feedback interfaces. Within industrial automation cells, the module closes position, velocity, and torque loops for a single axis while also executing local logic. It also forwards diagnostic data, giving the system a compact control and drive solution in one platform.

The controller provides 11 digital inputs and 4 digital outputs for high-speed interlock, homing, and trigger tasks. Its fiber-optic SERCOS II channel operates at 16 MBaud, allowing synchronized cycle times below a millisecond, while the front-panel RS-232 service port reaches 115 kBaud for parameter transfer and service access. The optional MA1 board adds two 12-bit analog outputs with a resolution of 12 bit plus matching differential inputs, so process values such as temperature, tension, or flow can be handled directly by the motion program. Resolver and HSF feedback lines connect through Encoder 1 so shaft position is sampled in phase with each network telegram.

Encoder 2 expands feedback compatibility by accepting EnDat 2.1, 1 Vpp sine-cosine, or 5 V TTL signals. The port supplies 5 V to the connected transducer, while HSF devices on the first port receive 8 V. Resolver excitation runs at 4 kHz, which keeps induced voltages in a narrow band for accurate demodulation even on long cables. An onboard relay rated at 24 V, 1 A can switch brakes, contactors, or sensor power without an external interface module, and the MA1 analog group mirrors the differential input set while remaining isolated from the digital sections.
