Product Description:

The CSB01.1C-PL-ENS-EN1-L1-S-NN-FW is a drive controller section in the CSB Drive Controllers series from Bosch Rexroth Indramat. Mounted beside power modules, it executes the regulation tasks that keep synchronous and asynchronous motors on setpoint while exchanging status data with machine-level PLCs through its built-in fieldbus and parallel links. By combining encoder evaluation with current loop processing, the section supplies deterministic position and torque commands that maintain repeatable motion in automated production lines, packaging cells, and material-handling stations.

This unit draws only 8 W of base power and refreshes its current control loop every 125 µs, allowing high-bandwidth torque corrections without appreciable heat gain. Internal logic and sensor boards receive operating voltage from the PL group at DC 24 V. Cabinet layout is supported by a height of 241 mm and a slim width of 49.5 mm. The EN1 feedback inlet is a D-Sub 15-pin female connector for Hall sensor format signals as well as resolver reference. A second D-Sub 15-pin female inlet marked ENS accepts encoders that require a dedicated supply. Command words, status bits, and startup parameters are exchanged through a D-Sub 37-pin parallel connector, while a D-Sub 9-pin female socket provides the starting-lockout path and carries the interlock signal.

The housing reaches a depth of 103 mm, so the device fits shallow control cabinets and still clears cable bends. Sixteen digital inputs and sixteen digital outputs, shown collectively as 16 In / 16 Out, share the parallel header and support sequence control without additional I/O cards. Encoder channels on EN1 can receive a resolver carrier of 18.2 Vpp. The ENS port can sink up to 500 mA for photoelectric encoders with higher supply demand. The parallel interface consolidates I/O exchange with command handling, while the separate lockout connection keeps the interlock path isolated from encoder wiring.
