Product Description:
The CSB02.1A-ET-EC-NN-NN-NN-NN-FW is a compact drive controller module manufactured by Bosch Rexroth Indramat as part of the CSB Drive Controllers series. When integrated with servo inverters and feedback devices, this controller manages axis motion, coordinates fieldbus traffic, and supervises machine status data within industrial automation cells. It regulates speed, torque, and position loops for electric drives across packaging machines, handling robots, and material transfer lines.
It draws 17 W of internal logic power during normal operation, so cabinet heat load is minimal. At startup, the supply experiences an inrush of <5 A lasting no longer than 1 ms, which simplifies fuse sizing. Motion feedback devices can be powered directly from the unit; the combined encoder outputs are limited to 6 W, with a per-channel ceiling of 500 mA, which helps prevent cable overheating. The board offers one ±10 V analog input, seven digital inputs, two probe inputs for position capture, and one configurable digital I/O channel, allowing mixed signal acquisition without extra cards. A Multi-Encoder interface accepts incremental or absolute encoders and passes position data to the control loop.
For networked installations, the communication layer is Multi-Ethernet, which supports real-time protocols over the physical medium defined as 100Base-TX. A shielded RJ-45, 8-pin jack serves as the single port, and signaling follows the IEEE 802.3u standard for interoperability with commercial switches. The link accommodates encoder and I/O traffic while leaving bandwidth for diagnostic telegrams. The configurable interfaces can be reassigned to map field events directly onto network variables. This arrangement supplies deterministic state data to higher-level PLCs while supporting low-latency drive control.
