Product Description:

The CSB01.1C-SE-ENS-ENS-L1-S-NN-FW is a plug-in control section that Bosch Rexroth Indramat supplies for its CSB Drive Controllers series. When mounted in a compatible power section, this unit governs individual or multiple servo axes, handling position, velocity, and diagnostic tasks inside automated machinery. It communicates motion commands and status data between drives, higher-level PLCs, and safety circuits, allowing the controller rack to coordinate precise, repeatable production cycles on factory lines.

This control section offers 3 configurable digital or analog I/O points for user signals and completes a current regulation update every 125 µs, so torque demands are followed with minimal lag. Two feedback channels accept incremental or absolute devices through a D-Sub 15 female connector, and the encoder logic is powered by 11.6 VDC. Dual feedback lets the application monitor gantry pairs or secondary axes with a common controller. Motion data is exchanged on the real-time SERCOS II network, while an onboard RS-232 service port supports setup and diagnostics. Pulse-width modulation inside the drive can be switched up to 8 kHz, matching high-speed motor models without audible ringing. The section sources field transducers through an auxiliary output rated at 24 VDC / 0.5 A, which can power external sensing devices.

The ready relay can energize external contactors with a load of 24 VDC / 1 A, providing a hardwired acknowledgment path for machine controllers. A built-in starting lockout function and a safety input that senses 24 VDC at 3 mA support emergency-stop chains, while motion is brought to rest under the Category 0 stop classification. The housing measures 49.5 mm wide, 103 mm deep, and 241 mm high, so multiple sections can be grouped on a cabinet rail without exceeding standard enclosure depths.
