Product Description:

The CSB01.1C-PL-ENS-NNN-L1-S-NN-FW is a single-axis control section from the CSB Drive Controllers series manufactured by Bosch Rexroth Indramat. Installed inside an IndraDrive power section, the board handles motion commands, field-level feedback, and safety interlocks for one servo or spindle axis. By processing encoder data and coordinating drive signals, it forms the logical core of a closed-loop drive system in industrial machinery such as packaging stations, pick-and-place modules, and material handling equipment.

Control electronics on the module draw 24 V DC from the cabinet supply, so low-power logic remains active even when the main bus is off. Internal analog-to-digital conversion operates with a resolution of 12-bit, allowing precise interpretation of command values transmitted through the parallel interface. Feedback arrives over the ENS encoder channel and is connected to a 15-pin D-Sub socket, while the board forwards a stabilized excitation of 11.6 V DC to the sensor. Line termination on that channel is fixed at 120 ohms to match differential transmission impedance and suppress reflections. Each signal group is DC-isolated to protect downstream electronics from ground loops that could arise during high-frequency switching.

Machine integration resources are concentrated on the front edge. Emergency stop wiring follows the drive’s safety profile and satisfies Stop Category 0 requirements through a 9-pin D-Sub lockout header. Peak power-up demand stays below 4.5 A, so standard control transformers can feed the board without oversizing. Command channels include a D-Sub 37-pin master connector that carries the parallel interface, giving the application 16 parallel inputs and an equal number of outputs for direct contact with PLC signals. A galvanically separated channel marked RS-232 provides diagnostic access, and the serial standard is available on a shielded service jack.
