Product Description:

The CSH01.1C-NN-EN2-NNN-NNN-S1-S-NN-FW is a controller card built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It serves as the motion-control core inside Rexroth drive systems, where it processes encoder feedback, generates command values, and coordinates axis-level tasks in packaging, material handling, and general factory automation. This role lets the card bridge higher-level machine commands and the internal control functions required for closed-loop motion. Because the card sits at the control layer of the drive, it must handle both motion feedback and machine-interface tasks within the same assembly. Serial communication is available through the front connector and supports rates to 115 kBaud over cable runs to 15 m, so host systems can exchange parameters and diagnostic data without boosters.

The analog output channel is limited to 1 mA of sink or source capability and up to 5 V, allowing it to provide reference signals to compatible external inputs. Each increment on that output corresponds to 19.5 mV/inc, giving fine resolution for torque or velocity trimming. During power-up, the card can draw an inrush current of 4 A for as long as 100 ms, so cabinet fuses and supply wiring must tolerate that short-term surge. Normal operation dissipates 7.5 W, and the onboard relay can switch up to 1 A at 30 VDC. The front S1 port uses a D-Sub 9 female connector for PLC diagnostics and accepts a 24 V, 3 mA input while sourcing 0.5 A to external indicators.

Encoder interface EN2 is supplied with 5.0 VDC at up to 350 mA. It is protected by an internal series resistance of 35 Ω, which helps secure differential signaling without overloading the transducer. The board’s relay outputs share the same 24 VDC field voltage noted earlier, providing galvanic isolation for machine-ready or fault lines. Separating the relay circuits from the encoder supply helps the card handle field-status signals and feedback connections on the same module.
