Product Description:

The CSB02.1B-ET-EC-NN-L3-NN-NN-AW drive controller is produced by Bosch Rexroth Indramat within the CSB Drive Controllers series. It forms the control section of a modular servo drive and attaches to HCS or HMS power stages to orchestrate motion tasks on single-axis and multi-axis machinery. In an automation cell, it processes feedback, executes torque loops, and relays setpoints so that connected motors follow commanded profiles with consistent accuracy. This arrangement separates command processing from power conversion, which helps the system coordinate axis behavior across a modular drive platform.

Network interfacing is handled through IEEE 802.3-compliant hardware, and the controller negotiates speeds over 100Base-TX copper links. The Ethernet interface provides a direct copper connection for standard industrial cabling. The port uses an RJ-45, 8-pin jack and supports Multi-Ethernet protocols, so EtherNet/IP, PROFINET, and EtherCAT nodes can share the same board. Two probe inputs register precise position marks, while the integrated Multi-Encoder Interface accepts EnDat, SSI, and other serial sensors without daughter cards. The ET plug-in consumes only 2.7 W, allowing dense cabinet layouts, and three optional slots remain open for additional functions such as safety or fieldbus extensions.

The logic layer manages 11 discrete inputs for limit switches and uses 5 reconfigurable lines that can act as outputs when interlocking multiple axes. Safe disabling of power is inherent because the board includes STO (Safe Torque Off) circuitry, so no external contactors are required for Category 0 stops. The L3 extension draws just 1.0 W, minimizing thermal load on passive cooling schemes. Two analog outputs can scale speed references to legacy drives, and the controller supports HCS02, HCS03, HCS04, HMS01, and HMS02 power sections for use across different inverter ratings.
