Product Description:
The CSH01.1C-NN-ENS-MA1-MD2-NN-S-NN-FW is a single-axis drive controller card produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in compatible IndraDrive power sections, this card handles feedback, I/O processing, and command execution for servo drives used in automated packaging, handling, and machining equipment. Its role is to translate higher-level machine instructions into precise current and velocity commands while collecting encoder data for closed-loop motion control, eliminating separate PLC channels for axis-related tasks.
The card is powered from a 24 V DC control supply, allowing the logic to stay active even when the main drive bus is de-energized. On power-up, it momentarily draws 4 A of inrush current, a figure that informs fuse sizing and cabinet supply design. Motion commands that originate from the machine controller are conditioned through the MA1 analog front end, which offers 2 differential analog inputs. Each input accepts signals within a ±10 V input range, and the converter samples them with a 12-bit input resolution, providing 4096 discrete levels for speed or torque references. The ENS interface delivers 12 V encoder excitation, and the built-in SSI evaluation block processes absolute position feedback without additional hardware.
Commanded values and diagnostic variables can be retransmitted through 2 analog outputs that share the same 12-bit output resolution, enabling proportional valve control or analog feedback to legacy systems. For binary signaling, the MD2 module integrates 16 digital inputs and 16 digital outputs; these channels permit start-enable, limit switch, and actuator control directly from the card without external relays. A maximum pulse width of 100 ms on the fast-counter inputs supports basic event timing, and an RS232 serial interface is available for parameterization or firmware updates when fieldbus communication is not equipped.
