Product Description:
The CSB02.5B-ET-EC-EC-SB-NN-NN-NW is a modular drive controller issued by Bosch Rexroth Indramat within the CSB Drive Controllers series. Designed for motion-centric automation, the unit coordinates servo and spindle axes by processing encoder feedback and forwarding commands to a separate power stage. In a production cell or machining center, it functions as the logic front end, connecting sensors, actuators, and field networks so that motor speed, position, and safety states are regulated in real time. Because the electronics are separated from the power section, the control unit can be serviced without disturbing high-current wiring. This arrangement lets the controller focus on command processing, network exchange, and feedback evaluation while the matched power unit handles motor current.
Control power enters through a DC 24 V line that feeds the processor, interface logic, and status relays. The panel offers 11 optically isolated digital inputs for limit switches or start-stop signals, and five configurable digital I/O channels can be assigned as extra inputs or outputs. A differential analog channel samples process signals at 14-bit resolution. The built-in Multi-Ethernet port supports SERCOS III, EtherNet/IP, PROFINET, and EtherCAT. Functional safety travels on a Safe Motion Bus that lets axes execute certified stop functions without removing drive power. Two probe inputs capture position latches with sub-microsecond latency, and the primary encoder port accepts feedback through a multi-encoder interface that is mirrored on a secondary port for dual-loop applications.
System flexibility comes from 3 optional slots that hold add-on fieldbus, safety, or I/O cards. The relay driver can switch up to 1000 mA, allowing direct actuation of brakes or interlocks. Encoder supplies deliver 500 mA at both 5 V and 12 V, but total consumption is capped at 6 W to protect the logic rail. All command data is routed to the matched power section HMU05, keeping high current away from the control board and easing thermal planning. This separation also helps keep the low-voltage control section isolated from the higher-power output hardware during operation.
