Product Description:

The CSH01.1C-NN-ENS-ENS-MEM-NN-S-NN-FW is a motion-logic control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It installs on compatible drive units and provides axis management, encoder processing, and I/O handling for modular automation lines. By coordinating feedback and command signals, it enables precise velocity and position loops between the power stage and higher-level PLCs. Typical applications include packaging stations, handling robots, and material transfer modules where compact control hardware reduces cabinet space.

Power for the board is drawn from a 24 V DC control supply, and initial energization is limited by an inrush peak of 4 A, protecting upstream fusing when the drive cabinet powers up. Once running, the module dissipates only 21.5 W, a figure that eases thermal design in densely packed racks. The two digital outputs can each source 500 mA for contactors or indicator lamps, while a buffered analog channel provides 5 V at 1 mA for transducer reference. High-speed positioning commands reach the power stage through the emulation block that delivers a 1 MHz pulse train, allowing fine interpolation of motor feedback.

Position signals are reproduced for external master devices over a shielded span of 40 m, maintaining timing integrity even at the specified 100 ms maximum pulse width. The dual encoder ports use the ENS + ENS standard and the MEM emulation format; the associated sensor rail supplies 11.6 V to incremental or absolute encoders. A form-C relay rated for 1 A supports status signaling, while asynchronous diagnostics travel on the serial interface at 115 kBaud because the card does not include dedicated fieldbus communication. No integrated safety technology is present, so protective functions must reside in an external circuit.
