Product Description:

The CSH01.1C-PL-NNN-MA1-MD1-NN-S-NN-FW control section is built by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It mounts on the backplane of Rexroth multi-axis drive systems, where it manages closed-loop motion control, signal conditioning, and machine I/O coordination. In automated equipment, the module acts as the command processor that converts analog feedback, digital status words, and fast parallel trigger signals into synchronized commands for inverter and servo modules. This arrangement lets one control section coordinate axis commands and supporting machine signals from a single slot in the drive stack.

The MA1 mezzanine provides two differential analog inputs, and each input has a high 160 kΩ impedance so connected transducers are not heavily loaded. These analog channels operate within a ±10 V range, while data exchange with higher-level control hardware is handled through a parallel interface rather than serial polling. For binary signaling, the MD1 section includes 12 digital 24 V inputs for real-time status capture. A built-in transistor stage can source up to 0.5 A at 24 V, which allows small lamps or pneumatic valves to be driven directly. Input conversion uses high-resolution ADCs to preserve measurement detail during closed-loop operation.

The MD1 section also provides 8 digital 24 V transistor outputs with fast response for discrete control tasks. On the analog side, two outputs are generated through a 12-bit DAC, and the controller uses the same signal range for those channels. A 40-pin header makes available 16 parallel inputs and 16 parallel outputs for word-wide handshaking with neighboring controllers. This layout supports direct connection to external logic hardware without an added interface board. A changeover relay rated at 24 V DC and 1 A can disconnect contactors during a fault, and an onboard analog input supports tachometer feedback without requiring an extra interface card.
