Product Description:
The CDB01.1C-S3-EN1-EN1-NNN-MEM-NN-S-NN-FW control unit is produced by Bosch Rexroth Indramat within the CDB Control Units series. This card plugs into an IndraDrive power section and coordinates two servo axes, translating motion commands from a PLC into drive-level signals for industrial automation tasks such as packaging, handling, or machining. It serves as the motion-control layer inside the drive assembly, so command processing and axis coordination remain integrated with the power electronics rather than being handled by a separate external module.
For local command issuance, the unit provides an analog output channel that sources up to 1 mA, and the same channel can swing to 5 V for proportional speed or torque references. The controller supervises 2 coordinated axes and exchanges cyclic setpoints via SERCOS III, which supports deterministic communication between the PLC and the drive. Two feedback ports accept resolver and HSF encoders, and both ports are energized by 8 V DC to power the sensors directly. When virtual feedback is required, an internal generator delivers incremental or SSI emulation so downstream devices receive position information without additional hardware. This arrangement allows the control unit to work with both physical motor feedback and simulated position signals in mixed automation systems.
Parameter cloning and update functions use the MEM interface, whose flat cable may extend to 40 m. That channel drives a differential pair capable of 20 mA, and it clocks at 1 MHz to move diagnostic snapshots in real time. Remote monitoring is available over a 100Base-TX link that follows IEEE 802.3u and terminates on an RJ-45, 8-pin connector. A Form C relay with contacts rated at 24 V DC, 1 A allows safety interlocks to remove drive enable under fault conditions. The resolver reference signal is generated at 18.2 Vpp and 4 kHz to maintain clean sine and cosine waveforms for angle decoding. These service and interface functions support data access, fault handling, and stable feedback processing within the same control unit.
