Product Description:
The CSB02.1B-ET-EC-PB-NN-EM-NN-AW is a control section produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. When mated with an HCS or HMS power module, it forms the command layer of a servo axis in automated machinery. Its role is to translate fieldbus commands, process sensor feedback, and execute drive algorithms so that torque, speed, and position targets are met in real time.
The control section furnishes 11 digital input channels for limit detection, drive enable, or high-speed interrupts, while 3 analog inputs capture ±10 V reference signals from transducers. Feedback or diagnostic values return through 2 analog outputs that can source 10 mA each. For Ethernet diagnostics or PLC exchange, the module supports 100Base-TX through a shielded RJ-45 port with auto-MDI. Internal logic and encoder supply are powered from a DC 24 V feed delivered by the system bus. Beyond the fixed I/O, five configurable digital points can be set as inputs or outputs, and two probe inputs latch position for print-mark detection. Three option slots accept encoder cards, extra fieldbuses, or safety modules.
Average logic demand stays at 17 W, reducing thermal load inside the control cabinet. Startup is simplified because inrush current stays below 5 A, so standard 24 V supplies do not require soft-start circuits. The probe circuitry recognizes position triggers with a minimum pulse width of 1 ms, enabling precise synchronization between encoder feedback and machine events. For fieldbus communication on legacy installations, the integrated Profibus interface follows the EIA-RS485 standard; it draws only 75 mA from the network while maintaining data rates up to 12 Mbit/s. When clipped onto HCS02, HCS03, HCS04, HMS01, or HMS02 power sections, automatic detection transfers rating information so the combined drive can be set up through a single parameter set.
