Product Description:
The CSB01.1N-SE-ENS-NNN-NN-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. Installed inside a multi-axis inverter rack, the board provides signal conditioning and fieldbus links so the converter can follow motion commands while monitoring feedback devices. Within an automation cell, it translates SERCOS telegrams, supervises encoder supplies, and energizes local digital I/O. By combining these functions on one module, the design reduces panel space and wiring needed for coordinated servo or spindle axes.
The module operates from a regulated backplane supply of 24 VDC, drawing up to 15.5 W during normal processing and diagnostic activity. Three combined digital I/O points are available; the local power rail can furnish 1.1 A to external sensors or actuators, while each input sinks only 3 mA and each transistor output can switch up to 0.5 A to ground. A pluggable relay offers 24 VDC switching at 1 A for galvanically isolated functions that exceed transistor limits. For deterministic motion sequences, the onboard SERCOS interface transmits and receives telegrams at up to 16 MBaud; the fiber-optic transceiver itself draws 2 W, and an optional front-mounted operator panel uses a separate 1 W allowance. Encoder ports supply 11.6 VDC at 300 mA for sine-cosine or EnDat sensors.
During startup, the control section presents an inrush demand of 5 A for no longer than 40 ms, permitting standard 24 VDC supplies to stabilize before foldback protection is triggered. High-speed probing inputs are scanned with a response time of only 1 µs, making the card suitable for position capture tasks such as flying saws or press synchronization. Internal signal processing, including position interpolation, is handled by electronics budgeted for 6 W of dedicated encoder evaluation power.
