Product Description:

The CSB01.1C-S3-ENS-MA1-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. It steers one drive channel in automated machinery by translating field signals into torque or velocity commands for the connected power module. Intended for packaging, handling, and metal-cutting equipment, the board executes deterministic motion loops on a single axis while integrating local sensor and actuator wiring.

Signal conditioning is handled through 2 Diff. ±10 V analog inputs that accept external setpoints and 2 × ±10 V analog outputs that stream feedback such as actual speed. Both directions share a 12 bit conversion depth, giving 4096 incremental steps per full-scale swing. Because the controller is classified as Single-Axis, its processing resources are dedicated to one motor, reducing scan latency. Five opto-isolated digital inputs—indicated by the value 5—capture limit, home, or emergency signals. Three additional configurable I/O lines can be programmed as status flags or handshakes, and a relay rated for 24 V DC at 1 A switches peripheral loads such as motor brakes or contactors.

Network access is provided through an RJ-45, 8-pin connector that runs 100Base-TX Ethernet when the unit operates on the real-time Sercos III bus. Commissioning software can reach the control section via the legacy RS232 port, useful during stand-alone testing. For position feedback the board offers a D-Sub 15 Female encoder interface that delivers 11.6 V at up to 500 mA to power the sensor; this self-contained supply removes the need for external excitation. The encoder resolution aligns with the analog quantization so that position words and command values use a comparable numerical width, simplifying scaling inside application code. Together, Ethernet motion control, serial diagnostics, and powered encoder support let the module fit seamlessly into both new installations and retrofit projects.
