Product Description:
The CSB02.5B-ET-EC-PB-NN-NN-NN-NW is a drive control section produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. It forms the control layer of a modular servo drive, coordinating motor torque, speed, and position loops in industrial automation systems such as packaging, printing, and material-handling lines. The device houses communication, processing, and feedback interfaces that link the attached power stage to PLCs and field-level sensors. In a modular drive layout, this separation lets the control section handle command processing while the paired power section supplies motor current.
The controller operates from a 24 V DC logic supply, and the electronics draw 17 W in standby to keep cabinet loading low. It provides 3 analog inputs for setpoint voltages related to speed or torque commands, and 2 x ±10 V analog outputs can retransmit internal variables to external recorders or monitoring devices. For discrete control, it includes 11 digital inputs that respond to fast signal changes, while five additional ports can be configured as inputs or outputs without rewiring. A built-in Multi-Ethernet module supports Ethernet/IP, PROFINET, or SERCOS over the same port, reducing the need for separate interface hardware.
The control section also supports flexible feedback and expansion options for systems that use different encoder types or require later feature additions. The multi-encoder interface accepts several encoder formats, and two probe inputs capture precise edges for registration tasks. Five configurable digital I/O points support handshake signals, and three optional slots allow the installation of safety, encoder, or additional bus cards. Integration with the HMU05 power section creates a complete axis amplifier, while the dedicated PROFIBUS-DP port provides deterministic cyclic data exchange when Ethernet is not available. Power demand from the communication daughterboards remains low, with the ET Ethernet card requiring 2.7 W, while the EC and PB cards each consume 1.1 W to limit heat buildup in compact enclosures.
