Product Description:

The CSB02.5B-ET-EC-EP-S4-DA-NN-NW is a programmable drive controller manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. It sits between higher-level automation systems and the power stage, translating motion commands into time-critical control signals for electric servomotors. Within conveyor, packaging, and robot stations, the device coordinates axis speed, torque, and safety states so that production sequences remain accurate and downtime is minimized.

In its analog layer, the module offers 2 ±10 V analog outputs that can transmit velocity or torque references to external devices. Feedback channels include a total of three analog inputs with a current path impedance of 300 Ω and a conversion depth of 12-bit, enabling low-noise acquisition of process values such as load cell currents. Digital connectivity is extensive: there are 11 digital inputs for limit switches, five configurable digital I/O points, and a plug-on digital and analog I/O extension for application-specific signals. Command and diagnostic traffic is carried simultaneously over the Multi-Ethernet interface, allowing the same hardware to join EtherNet/IP, PROFINET, or EtherCAT networks without changing option cards.

For additional customization, the controller supplies 3 optional slots for encoder feedback, fieldbus, or memory modules. Two probe inputs capture high-precision edge positions, while the relay path tolerates 1000 mA and up to 30 V when actuating contactors or status lamps. Safety is integrated: Safe Motion logic can source a maximum of 350 mA on the safe output channel and verifies speed or standstill without external relays. Electrical isolation for voltage monitoring is aided by a 300 kΩ input resistance and 14-bit resolution on the voltage channels, supporting deterministic reaction to overvoltage events.
