Product Description:

The CDB01.1C-SE-NNN-NNN-NNN-NNN-L1-S-NN-FW is a modular control section produced by Bosch Rexroth Indramat for the CDB Control Units series. This plug-in card installs into IndraDrive power sections and forms the real-time interface between motion commands and power electronics. In multi-axis machines, it manages setpoints, feedback, and fieldbus data so that servo drives follow programmed profiles used in packaging, printing, and material-handling lines. By separating control functions from the power stage, the platform can be matched to different machine requirements without changing the basic inverter hardware.

The card provides two programmable analog outputs whose digital-to-analog path is handled by an 8-bit converter. Each channel settles within 10 µs, delivers up to 1 mA of source current, and maintains linearity when terminated with the specified 5 kΩ load. Output steps are quantized at 19.5 mV per increment, allowing external devices to follow velocity or torque references with adequate granularity for mid-range servo loops. When applications require incremental torque trimming, the limited word length remains acceptable for coarse correction tasks. A dedicated RS-232 port supports local setup and diagnostic tracing, while the minimum SERCOS bus cycle of 1000 µs accommodates legacy motion controllers.

In coordinated systems, the unit supervises up to 2 drive axes and exchanges cyclic setpoint data over the SERCOS II fiber ring. The current control loop refreshes every 125 µs, so motor currents remain tightly aligned with dynamic command changes issued by the master. A built-in Starting Lockout safety function prevents unintended motion until the enable sequence is satisfied. Nine-pole L1 terminals route the 24 V logic supply, and the card draws 3 mA from this rail for its optically isolated inputs. The control section handles command processing and safety-related enable logic, while the paired power section supplies the motor energy needed for axis motion.
