This is a Bosch Rexroth IndraDrive control section, type CSB02.1A-ET-EC-EM-L3-NN-NN-FW, material number R911340993, with its standard display and keypad control panel. A control section is the plug-in control and communication unit of an IndraDrive servo drive; it carries the drive's firmware, communication and encoder interfaces.
What does the type plate say?
The front label reads "CSB02.1A-ET-EC-EM-L3-NN-NN-FW", MNR R911340993, FD 16W11, SN 7260406123718, AG1, CE, Made in Germany. The front plate has a yellow "Safety on Board" sticker.
What do ET, EC, EM and L3 mean in the type code?
Distributor listings for this exact type code describe ET as Multi-Ethernet master communication, EC as the multi-encoder interface, EM as encoder emulation and L3 as the Safe Torque Off (STO) safety option; NN means no module in that position. The Multi-Ethernet interface can be set to protocols such as Sercos III, EtherCAT, PROFINET IO and EtherNet/IP.
