The CSH01.SE-ENS-NNN-NNN-S2-S-NN-FW from Bosch Rexroth Indramat is a control unit in the CDB Control Units series featuring a Sercos II communication interface with deterministic data transfer. It operates on 24 V DC, draws a max 1.1 A on digital I/O, and supports RS232 for diagnostics. Standard encoder evaluation, 2×±10 V analog inputs, 2×0–10 V outputs, and cycle times of 125 µs (current), 250 µs (velocity), and 500 µs (position) enable precise motion control.
