Product Description:

The CSB01.1C-CO-ENS-MEM-L2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. Installed in the control slot of a Rexroth power module, it supervises real-time motion of a single servo axis and links the drive to higher-level PLCs and safety circuits in automated machinery. A front-mounted operator keypad of Standard design gives local access to status messages, fault codes, and jog functions without relying on the network connection.

This section commands exactly 1 axis, so its internal logic, memory allocation, and feedback ports are tailored for dedicated single-channel positioning rather than multi-axis coordination. Network connectivity is provided through CANopen and DeviceNet, and these fieldbuses carry setpoints, status words, and diagnostics without additional gateway hardware. Position feedback arrives over a multi-protocol encoder interface that accepts IndraDyn, Hiperface, 1 Vpp, and 5 V TTL signals, allowing one board to read both absolute and incremental transducers used on different motor types. To meet functional safety requirements, the board includes a hardware-based Safe Torque Off circuit that removes drive power when an emergency stop is requested or when the safety chain is opened. A built-in RS232 serial port provides a simple point-to-point link for parameter access when fieldbus communication is unavailable.

The controller exchanges status bits and start commands using integrated digital I/O, so no extra terminal module is required, and its onboard relay output can energize contactors directly from the logic board. Parameters and application data are stored on a removable MultiMediaCard, which keeps user data separate from the main board and supports reuse of saved settings in compatible units. The option slot supports encoder emulation, allowing downstream inverters or legacy CNCs to receive synthetic encoder signals directly from the section when an additional feedback signal is needed.
