Product Description:
The Bosch Rexroth Indramat CSH01.3C-ET-ENS-MEM-CCD-L2-S-NN-FW is a plug-in control section from the CSH Advanced Controllers series. It mounts inside an IndraDrive power module and delivers motion logic, fieldbus routing, and safety interlocks for multi-axis industrial automation. By interpreting encoder data, generating pulse trains, and exchanging status with higher-level PLCs, the module coordinates drives and peripherals within packaging, assembly, and material-handling lines. It supports both analog and high-speed digital I/O on the same board. This arrangement keeps control functions close to the drive hardware while allowing the module to manage several machine tasks at the same time.
The onboard A/D converter has 12-bit resolution, giving 4,096 discrete levels for analog monitoring tasks. Base power consumption is 8.5 W, which simplifies cabinet thermal calculations. Network connectivity is provided through the Multi-Ethernet interface, and its physical layer follows 100Base-TX so standard Cat5e cabling can be used. Control loops are clocked by the MEM output that reaches 1 MHz, while digital inputs accept TTL edges up to 400 kHz. For single-ended sensor lines, the ENS input presents 120 ohm termination to reduce reflections. The card draws its logic supply from a DC 24 V bus and limits output pulse width to 100 ms to protect downstream drives.
Cross-axis data sharing is handled through Master via SERCOS III, giving cyclic telegrams at drive level without extra cabling. The module supplies a steady 11.6 V to the encoder ports so feedback devices remain powered during brief bus dips. When the controller is first energized, it can momentarily draw 4 A of inrush, which should be considered when selecting circuit protection. Machine safety is integrated through Safe Torque Off, which disables power stages through redundant logic while leaving diagnostics active. Because diagnostics remain available after torque output is disabled, the controller can still report status information during a safety event.
