Product Description:

The CSH01.1C-PL-ENS-EN1-MEM-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. This plug-in module manages multi-axis motion, field I/O, and safety logic inside IndraDrive power stacks used across automated machinery and material-handling cells. By consolidating signal conditioning, encoder processing, and logical sequencing on a compact card, it forms the deterministic link between higher-level PLC networks and the inverter stage that energizes the motor.

It draws a regulated input of 24 V DC from the cabinet supply, and its base consumption is limited to 7.5 W, which helps keep thermal load low. Axis commands are exchanged through a parallel interface, while an auxiliary RS232 port handles diagnostics and parameter setting. Local machine signals connect to a block that offers 16 In / 16 Out digital channels, and each bit can be mapped directly to motion tasks. Primary feedback is handled by the onboard Standard Encoder Evaluation circuit, which provides 11.6 V DC to the sensor and supports absolute and incremental emulation streams. The timing logic can accept control pulses up to 100 ms and supplies 18.2 Vpp excitation for resolver windings, allowing mixed feedback chains without external conditioners.

At power-up, the board can draw a peak of 4 A, so upstream supplies must withstand the brief inrush. The secondary feedback input accepts Resolver and HSF devices, and its dedicated line delivers 8 V DC while the channel can source up to 500 mA to power transducers. Functional isolation is provided by Safe Torque Off, and a 24 V / 3 mA logic signal on the STO terminals disables drive output without relying on software intervention. With encoder links active and digital I/O toggling, communication queues are handled separately to prevent contention across motion cycles.
