Product Description:

Bosch Rexroth Indramat's CSB01.1C-ET-ENS-EN2-L1-S-NN-FW belongs to the CSB Drive Controllers series and is intended to command one servo or spindle axis inside an IndraDrive automation rack. The unit consolidates drive regulation, fieldbus communication, and encoder evaluation so that a host PLC receives ready-scaled position and status data without adding external interface cards. A standard operator panel on the drive front supplies parameter entry and basic diagnostics without linking a PC, and it provides local access to operating states and fault messages.

This controller is a single-axis model, so all closed-loop computations are handled for one motor channel. Machine signals can be wired directly to the board through its integrated digital I/O, which removes the need for small relay islands on the panel and keeps local signal wiring close to the controller. For high-resolution feedback, the optional module bay accepts an encoder board that recognizes EnDat 2.1, 1 Vpp, or 5 V TTL waveforms. Only 1 expansion slot is available, so the required function must be selected for the application. The base board already carries inputs for IndraDyn, Hiperface, 1 Vpp, and 5 V TTL encoders, allowing direct use with Rexroth and third-party motors. When extra process variables are required, the expansion functions can add analog I/O or generate emulated encoder signals for legacy controls.

User data and parameter sets can be copied to a removable MultiMediaCard for storage and transfer. Network traffic reaches the motion kernel through a Multi-Ethernet interface that supports common real-time protocols, so axis data can travel over the same cable plant as other plant stations. For hard-wired status, the board includes an integrated relay output that can energize contactors or lamp towers, while service access is available through the RS232 serial port for low-level diagnostics and direct serial communication.
