Product Description:

The CSB01.1C-PL-ENS-MEM-NN-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. This module forms the signal-processing hub inside a multi-axis drive, accepting encoder feedback, issuing logical commands, and coordinating power sections so that servo motors follow the programmed motion profile in industrial automation cells. It mounts directly on the base unit without additional wiring, reducing panel depth and keeping internal signal routing compact. Because the control section handles signal evaluation rather than motor power, it works as the logic layer of the drive assembly.

The card has a rectangular footprint. Its height is 241 mm, its width is 49.5 mm, and its depth is 103 mm, allowing it to fit alongside other controller sections on a standard mounting rail. At power-up, the circuitry draws an inrush of 4.5 A that lasts for roughly 110 ms, so the upstream supply must tolerate that short pulse. A D-Sub 37-pin PL connector provides access to 16 input and 16 output channels, and those inputs can accept TTL edge rates up to 400 kHz. The ENS interface presents 120 Ω of input resistance and requires a typical 11.6 VDC supply, which supports stable position-feedback transfer, while onboard relay contacts can switch 24 VDC at 1 A for auxiliary control duties.

During normal operation, the digital outputs can deliver up to 0.5 A per channel, while the shared I/O logic rail may draw as much as 1.1 A. Motion-capture inputs support incremental encoder signals with rates up to 1 MHz, and the synchronous-serial interface clocks up to 1000 kHz for absolute encoders, allowing fast feedback processing on high-speed positioning axes. Complementary MEM and SSI processing manage counted edges internally, and the PL interface passes data to the main drive processor in a deterministic manner. This arrangement supports consistent signal handling during coordinated drive operation.
