Product Description:

The CSB01.1C-PL-ENS-MA1-L1-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. Installed in a multi-axis rack, the board supplies the logic and communication layer that links a power section with upper-level PLCs in industrial automation cells. Within this role, it translates fieldbus telegrams, conditions encoder signals, and supervises safety channels so that servo axes follow commanded motion profiles without interruption.

The unit offers 2 differential analog inputs that accept process variables such as tension or speed references, and it mirrors commands through 2 analog output channels for downstream drives or indicators. Both analog rails share a ±10 V signal range, allowing symmetrical control around zero for bidirectional actuation. Discrete I/O capacity is provided by 16 digital inputs and 16 digital outputs; these terminals accommodate limit switches, ready contacts, and sequence interlocks that must be polled at the controller’s internal cycle rate. A dedicated 12 V rail powers incremental or absolute encoders and keeps feedback lines isolated from noisy mains potential.

Power-up behavior is characterized by a 4.5 A base inrush current that the cabinet supply must absorb while capacitors charge, after which continuous demand drops to an 8 W base power consumption in standby. Functional safety conforms to Stop Category 0, which removes drive energy without controlled deceleration, and a configurable Starting Lockout prevents unintended restart until an acknowledgment pulse is detected on the 24 V safety bus. Mechanical integration is straightforward because the control section uses keyed connectors and retains a slim 49.5 mm front width, keeping total rack depth at 103 mm and height at 241 mm for dense machine layouts.
