Product Description:

The CDB01.1C-S3-ENS-NNN-NNN-S2-S-NN-FW is a modular drive controller board manufactured by Bosch Rexroth Indramat within the CDB Control Units series. Installed in an IndraDrive platform, the board supervises axis motion, distributes fieldbus data, and executes safety functions for automated conveyors, packaging lines, and machine tools. It serves as the interface layer between the power stage and the machine control network. This arrangement lets the control section handle communication, feedback processing, and motion-related tasks within the drive system.

Signal generation uses an analog output resolution of 19.5 mV/inc, giving the drive fine command steps for torque or velocity loops. Network communication is handled over SERCOS III, providing real-time Ethernet exchange with PLCs and HMIs. Two transistor outputs can source up to 500 mA each, while the shared channel limit is 1000 mA for the output group, enabling direct actuation of small loads such as solenoids or tower lights. The ENS feedback port has an input resistance of 120 Ω, which helps reduce line reflections on differential encoder lines. For sensor power, the board supplies 11.6 V to support incremental and absolute encoders. A TTL capture channel records position markers at 400 kHz so brief reference pulses can be detected during motion. Safe Motion is available for certified velocity and standstill monitoring.

During energization, the unit draws an inrush current of 6 A for 60 ms, so the supply circuit must tolerate a brief startup surge before normal operation begins. After initialization, steady power consumption is only 9 W, which helps keep enclosure cooling requirements modest during continuous use. A 24 V DC relay contact rated at 1 A is included for ready or fault signaling to external control hardware. Serial diagnostics operate at up to 115 kBaud over cable lengths of up to 15 m, allowing service access from outside the cabinet. These diagnostic and signaling paths support status checking without requiring the connected device to be placed next to the control electronics.
