Product Description:

The CSB01.1N-AN-ENS-NNN-L2-S-NN-FW is a controller section produced by Bosch Rexroth Indramat within the CSB Drive Controllers series. Designed to manage servo axes in industrial automation lines, the module converts incoming command signals and supervises feedback for precise velocity and position regulation. It combines analog, digital, and relay resources on one compact board, allowing machine builders to condense control wiring inside the cabinet. This arrangement helps keep signal processing close to the drive electronics while separating control functions from the main power stage.

This variant supplies ±10 V scaling on its analog channels, letting a higher-level PLC transmit speed or torque references as differential voltages. The controller has isolated analog inputs, and each channel is sampled independently. The channel count is 2. Logic level sensing relies on a current of 3 mA at the digital inputs, so optocouplers or proximity switches must be able to sink that amount. For actuation, the controller offers transistor outputs that can drive up to 0.5 A to external relays, pilot valves, or beacons. Setup and diagnostic data are exchanged through a built-in RS232 port, permitting a direct point-to-point connection to a laptop or HMI without additional fieldbus hardware.

Motion capacity is limited to 1 mechanical axis, which simplifies multi-drive installations that assign one CSB section to each motor. An integrated encoder supply delivers 12 V to incremental or absolute feedback devices, eliminating the need for a separate auxiliary supply in the panel. For interlocking tasks, the onboard relay contact is rated at DC 24 V / 1 A, which is suitable for enabling drives or releasing brakes in control circuits. The controller section is intended for cabinet-mounted servo drive assemblies where compact signal conditioning helps reduce internal wiring and keeps feedback connections organized.
