Product Description:
The CSH02.5B-CC-EC-ET-L3-NN-NN-NW is an advanced motion controller manufactured by Bosch Rexroth Indramat and assigned to the CSH Advanced Controllers series. In an automation cell, it issues synchronized position, speed, and torque commands and acts as the master node that links servo drives, I/O, and sensor networks into one coordinated system. This role allows the controller to manage motion relationships across multiple machine functions while maintaining real-time control.
Signal processing resources are sized for high-resolution feedback. The multi-encoder interface supplies 5 V and 12 V rails, each capable of 500 mA, so incremental, absolute, or resolver devices can be powered simultaneously without exceeding the 6 W encoder power ceiling. Two differential analog channels are sampled with 14-bit resolution and a 1.3 kHz bandwidth, while additional control loops use a 12-bit EC A/D converter for fast auxiliary measurements. Configuration and diagnostics travel through a 100 Ω twisted-pair engineering link that reaches 100 m, and across this distance the controller sustains 100Base-TX traffic. For fieldbus integration, a Multi-Ethernet hardware layer is provided, and machine-level axis synchronization is handled by a SERCOS III master.
The controller includes an L3 supply section for brake-energy regeneration. During deceleration, it can absorb up to 400 mJ per event and deliver a continuous 350 mA to external shunt circuitry, preventing DC bus overvoltage. Safety is provided through Safe Torque Off, which isolates drive power channels immediately on request without relying on software state. Internal waveform generators support sinusoidal modulation up to 400 kHz and square-wave outputs of up to 1000 kHz, allowing precise test routines or carrier-signal generation for high-frequency actuators.
