Product Description:
The CSH01.1C-NN-EN2-MEM-MA1-S2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted on an IndraDrive power stage, it handles encoder evaluation, analog I/O, and safety functions to synchronize servo axes in automated machinery. By concentrating motion tasks on a plug-in board, the drive stays compact yet meets the fast response times required in robotics, packaging, and material-handling cells. This layout separates control functions from the power section while keeping both parts in one drive assembly.
The communication slot on this variant is not fitted, so network access can be added only by inserting an external fieldbus card. Encoder connector 1 accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals, and the adjacent EN2 service pin delivers a sense voltage of 5.0 V at up to 350 mA to power the measuring transducer. The MA1 analog I/O extension offers two analog inputs and two analog outputs; each input is digitized with a resolution of 12 bit, while every output is refreshed in 10 µs. This combination allows the control section to exchange command and feedback signals with nearby process devices without extra interface modules. It can support closed-loop tasks that combine axis control with external analog references.
The embedded MEM frequency output can toggle up to 1 MHz, so speed counters and position latches obtain precise edge timing directly from the drive. When the application requires simulated feedback, Encoder Emulation delivers selectable incremental signals without external signal conditioners. A dry contact on the S2 safety board is rated for 1 A, enabling direct interruption of motor ready lines or guard relays. Functional safety is addressed through the integrated Safe Motion package, which supplies drive-based monitoring for safe torque off, safe stop, and reduced speed modes. This gives the control section a direct link to both motion feedback handling and machine interlock circuits. It also reduces the need for separate signal conversion hardware around the drive.
