Product Description:
The CSB01.1N-SE-ENS-NNN-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. Designed as a modular plug-in board, it manages one servo motor axis and acts as the interface between the drive power stage and plant-level networks. In industrial automation, the unit executes motion commands, supervises feedback, and exchanges diagnostic data to support coordinated positioning and velocity control on packaging lines, handling gantries, and machine tools.
This section supports a single-axis architecture, and real-time telegrams travel through fiber-optic lines using the SERCOS II fieldbus. Internal logic is fed by DC 24 V, while the current regulators update every 125 µs for tight torque control. Startup surge is limited to 5 A with a maximum pulse width of 40 ms to protect upstream supplies. Digital inputs and relay outputs are available for limit switches or drive-ready signals, and the standard operator panel provides local status information. An ENS encoder evaluation channel accepts IndraDyn, Hiperface, 1 Vpp, or 5 V TTL feedback and provides 11.6 V excitation at 300 mA so multiple transducer formats can be supported.
On the network side, the controller sustains transfer rates of up to 16 MBaud, and the minimum frame repetition time is 1000 µs, allowing synchronized multi-axis interpolation across several drives. Typical electronics draw only 15.5 W, which helps with cabinet thermal planning. For service access or fallback operation, the embedded RS-232 serial interface provides command-line communication independent of the optical link. Continuous encoder sampling occurs inside the drive's internal loop without extending the active SERCOS cycle, and the low control-power demand allows multiple cards to share the same supply rail without nuisance tripping.
