Product Description:

The CSB01.1C-PB-ENS-MEM-L1-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. It plugs into a modular power section to regulate servo or induction motors in automated machinery. By combining motion control, feedback processing, and fieldbus communication on one card, the device streamlines cabinet layouts and reduces wiring complexity in factory automation lines. It serves as the command and feedback layer between the power stage and the higher-level controller during speed, torque, and position control.

This control section exchanges cyclic data over the PROFIBUS network and updates its current loop every 125 µs, so torque commands track drive demands without perceptible lag. Three combined I/O points can be assigned to fast local functions, while five dedicated digital inputs handle start, inhibit, or limit-switch signals close to the axis. Each digital output can source up to 0.5 A, which is sufficient for pilot relays or indicator lamps. Position feedback arrives through the IndraDyn, Hiperface, 1 Vss, or TTL encoder interface, and the ports supply 11.6 VDC at 300 mA to power many resolvers or absolute encoders without an external supply. Cabinet width is limited to 49.5 mm, allowing dense multi-axis groupings inside standard 300 mm deep enclosures where closely spaced drive assemblies are used.

A probe input captures position events with a latency of only 1 µs, which supports registration tasks on cutters or labelers. For auxiliary loads, the on-board relay is rated at 24 VDC and 1 A, and its single N/O contact can switch brakes or interlocks. Mechanical depth is 103 mm, while the overall height reaches 241 mm, which helps with thermal zoning and airflow planning inside the cabinet. The board’s safety layer implements a Starting Lockout so the axis cannot energize until the PLC releases it. Option slot 2 provides encoder emulation pulses for legacy drives, which can help when older downstream devices require simulated feedback signals.
