Product Description:

The CSB01.1C-S3-ENS-NNN-L2-S-NN-FW is a drive controller module produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. It functions as the command section of a servo drive, receiving motion tasks from a central control system and calculating current, speed, and position loops for the attached power stage. Within automated machinery, it supplies the real-time directives that allow a motor to maintain accurate trajectories during cutting, packaging, or material-handling cycles.

The module supervises one mechanical axis in a single-axis arrangement, so control is limited to one motor channel. Communication with upstream motion controllers is handled over SERCOS III, a deterministic Ethernet network that synchronizes position data across multiple drives. Local signaling is possible through the integrated Digital I/O, so sensors such as limit switches can be wired directly without additional interface cards. Rotor position feedback is accepted through a multi-protocol encoder port that supports IndraDyn, Hiperface, 1 Vpp, and 5 V TTL signals, allowing the controller to read incremental or absolute encoders from different motor families. Parameters and diagnostic logs can be transferred or backed up by the MultiMediaCard slot, allowing local data storage without a separate computer.

Functional safety is provided by Safe Torque Off; when this circuit is triggered, the drive removes torque-producing pulses from the power stage without relying on software. For setup or low-speed diagnostics, an RS-232 port is available, allowing terminal access when network communication is not yet active. Daily operation is handled through the standard operator panel, which provides basic keys and status LEDs. Status changes can be forwarded through an onboard relay output that provides a Form-C contact. No additional option cards are installed, so the unit remains compact for cabinets with limited space.
