Product Description:

The CSB01.1C-S3-EN2-NNN-NN-S2-NN-FW belongs to the CSB Drive Controllers series manufactured by Bosch Rexroth Indramat. It is a compact control section that plugs into an IndraDrive power module to create a closed-loop servo or spindle axis. By processing position feedback, evaluating fieldbus telegrams, and issuing pulse-width commands to the inverter stage, it coordinates motion tasks such as indexing, synchronized camming, and electronic gearing in automated machinery and material-handling lines. This arrangement places the control electronics directly at the drive so axis commands can be handled within the same module assembly.

This control section is configured for a single-axis topology, so one drive power stack is managed without master-to-slave current sharing. Communication with the PLC occurs over SERCOS III, a deterministic Ethernet network that provides synchronized setpoint exchange and diagnostics. For position feedback, it presents a selectable EnDat 2.1 interface that supports absolute encoders with digital bidirectional data as well as analog sine-cosine inputs rated at 1 Vpp/5 V TTL. A bank of digital I/O is available to map limit switches, probe triggers, or user LEDs directly to the controller. The front panel also exposes a maintenance port using RS-232 for local setup and service access.

The unit comes without an optional function module, and the reserved expansion position is identified as slot 1 for additional fieldbus or safety I/O functions. Application parameters are stored on a removable MultiMediaCard, so setup data remains with the control section during service. A programmable relay output is included for switching contactors or signaling fault conditions to external circuits. This layout keeps the base configuration straightforward while still allowing the controller to interface with essential machine signals.
