Product Description:
The CSB01.1C-NN-ENS-MA1-L1-S-NN-FW control section is manufactured by Bosch Rexroth Indramat and belongs to the CSB Drive Controllers series. Installed in modular Rexroth inverters, this unit manages feedback conversion and analog signal conditioning so motion axes can be governed by the higher-level automation system. Within an industrial cell, it translates field-level measurements into drive-level commands and returns status data to the PLC in real time.
Two differential analog inputs accept process signals, and they are configured as two differential channels. Each input is scaled for ±10 V, giving compatibility with most standard transducers. A front-end bandwidth of 1 kHz permits capture of moderately fast feedback loops without aliasing, while a common-mode rejection figure of 70 dB minimizes error introduced by ground offsets. The high input impedance of 1000 kΩ lets sensors drive the card without loading their outputs. Together, these parameters allow precise voltage acquisition, permitting the drive to adjust torque or speed according to external commands without distortion.
The board also generates control references through two analog outputs. These channels share the same ±10 V span as the inputs and provide 12-bit resolution, giving 4096 discrete steps for fine motor current modulation. For encoder feedback, the card integrates a converter with a cutoff frequency of 500 kHz, so it can process high-speed incremental streams without phase loss. The encoder port presents 120 Ω of input resistance and a stabilized 11.6 VDC supply that can deliver up to 500 mA, supporting most sine-cosine or TTL encoders. The housing measures 49.5 mm in width, 103 mm in depth, and 241 mm in height, allowing the controller section to fit beside other IndraDrive modules while maintaining airflow clearances.
