Product Description:

The CDB01.1C-S3-ENS-ENS-NNN-MA1-S1-S-NN-FW is a modular control section manufactured by Bosch Rexroth Indramat for installation in the CDB Control Units series of IndraDrive converters. This board supplies the processing and communication layer that links drive power stages with factory networks. By supporting two coordinated axes, it executes interpolation, diagnostics, and parameter management, allowing servo and spindle motors to follow programmed motion profiles with consistent accuracy in packaging lines, metal-cutting centers, and material-handling cells. Installed as the control layer of an IndraDrive converter, it separates motion processing from the power section while keeping coordinated axis control in the same platform.

Power draw at idle is 9 W, which helps limit panel heat buildup. Two Sercos ports implement a SERCOS III real-time Ethernet ring, so adjacent drives can be daisy-chained without an external switch. For position feedback, each encoder outlet can source 500 mA at 11.6 V, which is suitable for SinCos or Hiperface transducers with onboard electronics. During startup, an inrush of 6 A must be considered when selecting fuses and cabling. A single-line display on the front edge provides basic status codes and address information during operation. This front display gives a quick local view of operating state without adding separate interface hardware.

The integrated MA1 analog/digital module provides two voltage inputs and two voltage outputs, and it converts signals with a 12 bit resolution for finer scaling of pressure and speed commands than older 10-bit cards. The module can generate or measure pulses up to 60 ms wide for tasks such as valve energization or cam detection. Safety circuitry is separate from the main I/O path, and the safe relay can switch up to 0.5 A to remove power from external contactors. This arrangement allows standard control signals and safety functions to remain electrically separated inside the same control section. Physical network connections use shielded RJ-45, 8-pin sockets that carry data and timing signals within the Sercos ring.
