Product Description:
The CSH01.1C-S3-ENS-EN2-MEM-NN-S-NN-FW is an axis and communication controller module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. In multi-axis drive assemblies, it processes motion commands, handles fieldbus traffic, and links feedback devices so that the connected servo drives follow coordinated trajectories. By integrating analog channels, encoder interfaces, and Sercos III networking on one compact card, the module reduces cabinet wiring and acts as the central command element in industrial automation cells that require deterministic cycle times.
The controller’s local analog acquisition front end is dimensioned for velocity or process reference signals up to 1.4 kHz, so the input channel can track rapid setpoint changes without phase delay in closed-loop control. Its differential front end presents a high impedance of 160 kΩ, limiting sensor loading and voltage division errors. Conversion accuracy is assisted by a step width of 1.23 mV/incr, which supports fine granularity when scaling transducer outputs to engineering units. The analog output stage drives reference voltages into loads down to 5 kΩ and emits each new value with a resolution of 19.5 mV/incr. These combined figures show how precisely the module can command external amplifiers and read proportional actuators.
Logic and interface electronics draw their supply from a control rail at 24 V DC, allowing the card to stay active when the main power stage is shut down. For high-resolution position feedback, the En2 port provides an excitation of 5.0 V and can source up to 350 mA, while the ENS port delivers 11.6 V at 500 mA for multiturn encoders that require greater drive capability. The MEM output distributes reference pulses at rates up to 1 MHz over line lengths not exceeding 40 m, giving the drive package an auxiliary channel for step-direction devices. Dual Sercos III ports use 100Base-TX signaling through standard RJ-45 connectors and support ring or line topologies over 75 m of shielded cable.
