Product Description:

The CSH01.1C-PB-ENS-MA1-MD1-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It slots into a modular drive stack and acts as the communication and signal-conditioning hub between a higher-level PLC and the attached power modules. By combining fieldbus, encoder, analog, and digital channels inside one card, it supports coordinated motion in multi-axis automation without extra interface hardware. Its integrated layout also helps keep cabinet wiring compact when several axes share the same control platform.

The board communicates with the cell controller over PROFIBUS DP at up to 12 MBaud, so cyclic setpoints and diagnostics travel on a single shielded cable. For position feedback, the encoder input presents 120 Ω termination and accepts differential signals up to 500 kHz; this bandwidth accommodates high-speed servo encoders while the fixed impedance matches standard line drivers. An onboard regulator supplies the transducer with 500 mA at 11.6 V, eliminating the need for an external sensor power rail. Two differential analog inputs, two analog outputs, and twelve digital inputs share the same backplane timing, letting the motion loop sample local process variables and issue reference voltages within the same cycle instead of routing those signals through separate interface cards.

The MA1 module’s analog stages deliver and measure signals across a span of ±10 V with a 12-bit converter depth, giving 4.88 mV resolution for velocity, torque, or hydraulic valve commands. Eight digital outputs switch loads drawing up to 0.5 A each, allowing direct actuation of contactors or status lamps without interposing relays. For auxiliary position sensors, a TTL capture input records edge events to 400 kHz, so registration marks or encoder index pulses are time-stamped accurately even when the main bus is busy. This arrangement supports fast local signal handling without separate conversion hardware.
