Product Description:

The CSH01.1C-SE-EN2-MEM-MA1-S2-S-NN-FW is a motion-control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted inside a Rexroth drive rack, the unit coordinates multiple axes, processes local I/O, and applies integrated safety routines within industrial automation cells. Its principal task is to transform high-level program commands into deterministic drive and encoder signals so that packaging lines, pick-and-place robots, and machining centers can follow precise speed, torque, and position references without external latency.

Field communication is carried out through the SERCOS optical interface, enabling cyclic setpoint updates and real-time diagnostics to every connected inverter. Logic circuitry draws a steady 7.5 W and tolerates a startup inrush of 4 A, so cabinet power supplies and fusing must accommodate that brief surge. Local process data flow is handled by 2 analog inputs and 2 analog outputs that sample or generate voltages at 12-bit resolution, allowing proportional valve positioning or sensor scaling without external converters. A single-line control-panel display on the front edge gives numerical access to parameters for setup and fault review directly at the drive stack.

The encoder subsystem offers galvanically isolated emulation that produces clock and data streams up to 1 MHz while supporting SSI absolute and incremental formats. It supplies feedback devices with 5 V and supports link lengths of 50 m without sense conductors or 75 m when sense wires are present to correct voltage drop. Functional safety is implemented through Safe Motion, and a safety-rated encoder is required for that function. The section accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals, and the timing logic monitors pulses as wide as 100 ms so loss-of-feedback events can be detected even during very low-speed operation.
