Product Description:

The CSB01.1C-SE-ENS-MEM-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat and belongs to the CSB Drive Controllers series. It mates with a corresponding power section to create a complete drive controller that closes current, velocity, and position loops for servo and induction motors used in automated assembly, handling, and packaging lines. By linking motor feedback devices with the SERCOS fieldbus, the unit issues deterministic torque commands that synchronize multiple axes within an industrial motion system.

The module updates its current loop every 125 µs, which shortens reaction time when load conditions change. Through the SERCOS interface, it can request up to 0.6 Nm of torque per cycle, and diagnostic waveforms exit the EMU port at a ceiling of 1 MHz. Digital reference inputs on the TTL channels are accepted at frequencies up to 400 kHz, while incremental encoder signals pass an input filter set at 500 kHz to reduce noise. Position data is processed with 12-bit resolution for balanced accuracy. An auxiliary encoder rail supplies 500 mA, and a single normally open relay contact is provided for user I/O. The housing depth is 103 mm and the width is 49.5 mm, which supports cabinet layouts where space is limited.

The housing stands 241 mm tall and incorporates side terminals that forward encoder power independently of logic lines. That rail delivers 11.6 V DC at up to 20 mA from the EMU transmitter. The arrangement permits short-run differential signaling without external regulators. Heat is carried through the slim aluminum profile, so installation must allow unobstructed airflow around the unit. The normally open relay contact handles low-level switching for brakes or interlocks, and the stated encoder cutoff and input limits support reliable position capture when shielded cabling is used.
