Product Description:

The CSH01.3C-PB-ENS-EN2-CCD-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It plugs into an IndraDrive power module and acts as the motion and communication core for servo axes, converting application commands into deterministic drive signals while supervising the integrated safety circuit. By combining fieldbus management, encoder evaluation, and axis parameter storage in one slot, the module streamlines cabinet wiring in automated assembly, packaging, and material-handling lines.

An analog differential input accepts a span of ±10 V, allowing direct speed or torque references from PLC analog cards without extra scaling hardware. For cyclic data exchange over factory networks, the controller hosts a PROFIBUS channel that reaches 12 MBaud and terminates on a female D-Sub-9 connector, with additional bus access available through cross-communication ports X24 and X25. A service computer connects through an 100Base-TX socket that uses an 8-pin RJ-45, providing high-speed access for setup and parameter backup. The built-in safety channel supports the certified function Safe Torque Off; this function removes drive power through hardware gating rather than software commands. A maintenance port based on the serial standard RS232 is present for legacy diagnostic tools and startup tasks.

Primary encoder power is delivered at 12 V for MSK, HIPERFACE, EnDat 2.1, 1 Vpp, or 5 V-TTL feedback, while a secondary input supplies 5 V to redundant EnDat or incremental sensors so that multi-loop position control can be implemented. The relay output is rated for 24 V DC, 1 A, enabling direct switching of contactors or signal lamps when limit states are reached. Serial traffic over the maintenance port can be routed up to 15 m without repeaters, making it suitable for in-cabinet or adjacent-machine service access.
