Product Description:

The CSH01.2C-SE-ENS-EN1-CCD-L1-S-NN-FW is a motion and communication controller card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power section, it links field networks with drive electronics to manage axis position, velocity, and torque in automated production cells, packaging systems, and material-handling equipment. The card integrates encoder supplies, analog conditioning, and high-speed serial channels so that feedback and command data reach the drive processor with minimal delay. This arrangement lets one control section handle both signal processing and communication inside the same drive platform.

The controller processes voltage references through an analog input path that spans 1.4 kHz, and the associated input resistance of 160 kΩ helps prevent loading of external sensors. Conversion accuracy is aided by a 1.23 mV/inc resolution, allowing fine torque trim during closed-loop operation. A single analog output can source 1 mA, with each increment representing 19.5 mV, which suits proportional valve or inverter setpoints. Internal consumption remains low because typical base power is only 8.5 W, which reduces added heat inside the drive assembly. For deterministic motion tasks, the Sercos optical interface transmits cyclic data at 16 MBaud, while the onboard encoder channel supplies 8 V for Hall-sensor feedback and drives a resolver with 18.2 Vpp at 4 kHz.

During power-up, the card momentarily draws an inrush of 4 A, after which the ENS logic domain stabilizes at 11.6 V and 500 mA. Eleven discrete inputs permit direct reading of limit switches and sensor flags, with the maximum count identified as 11. Parameter access and diagnostics are also available through an asynchronous port running at 115 kBaud, which supports setup tasks and PLC handshaking. Supplemental 8 V supplies support encoder marker tracks, so position capture does not require external regulators. These local I/O and feedback functions let the drive gather machine status signals while maintaining stable communication with the surrounding motion system.
