Internal Product Review
The CSB01.1C-NN-ENS-EN1-NN-S-NN-FW is a Bosch Rexroth Indramat drive controller with low 8 W base power and a compact cabinet-friendly footprint. ENS feedback support with 11.6 VDC supply and 12-bit A/D resolution gives the unit strong signal handling for precise drive integration. A 4.5 A base inrush and 0.5 A digital output current round out a well-balanced controller for dependable machine control.

Product Description:
The CSB01.1C-NN-ENS-EN1-NN-S-NN-FW is a plug-in control section module in the CSB Drive Controllers series from Bosch Rexroth Indramat. It installs on an IndraDrive power base and carries the signal processing, encoder conditioning, and discrete I/O circuitry required for closed-loop servo operation. By acting as the logical bridge between the drive power electronics and the plant-level PLC, the board supports synchronized motion profiles, safety signal handling, and status reporting. Its role is centered on command processing and feedback evaluation rather than power conversion, so it works with the base unit to manage axis control. This arrangement lets the control section coordinate external commands with internal feedback so the axis can respond quickly to changing load and position demands in automated equipment.
At power-up, the board draws an inrush current of 4.5 A and then settles to a continuous power demand of 8 W. Each digital input operates at 24 VDC / 3 mA, while each transistor output can switch loads up to 0.5 A. The ENS analog front end uses a 12-bit A/D stage, and the associated input impedance is 120 Ω to support stable signal handling. Additional resources include 250 mA of EN1 HSF current from an 8 VDC source, a 4 kHz carrier for resolver tracking, an 18.2 Vpp resolver excitation, 500 mA on the ENS supply rail at 11.6 VDC, and a pulse stretcher that limits individual commands to 110 ms.
System timing is governed by a maximum pulse-width watchdog of 110 ms. For cabinet layout, the module has a height of 241 mm, a rack width of 49.5 mm, and a depth of 103 mm, which supports dense stacking beside inverters. Isolated feedback channels, dedicated resolver excitation, and controlled analog references help keep motion data accurate when the module is installed near high-energy switching hardware. The narrow form factor also leaves room for adjacent drive components in compact multi-axis cabinets. The isolated channel design helps maintain cleaner feedback signals where switching noise and tight grounding layouts are common.
