Product Description:

The Bosch Rexroth Indramat CDB01.1C-ET-ENS-ENS-EN2-MA1-NN-S-NN-FW control unit belongs to the CDB Control Units series and plugs onto an IndraDrive power section to create a complete drive. The board processes feedback, manages field networks, and issues reference commands that keep servo axes synchronized with higher-level automation. It is intended for packaging machines, gantry loaders, and metal-forming cells where compact dual-axis control and deterministic communication are required. Installation uses the standard operator panel for local parameter entry.

A double-axis architecture allows the card to command two motors while sharing encoder supply, which simplifies wiring in multi-head stations. The logic section draws only 9 W, so enclosure heat dissipation rarely changes the drive’s derating curve. Communications are handled by a Multi-Ethernet interface that negotiates SERCOS III, EtherNet/IP, or PROFINET frames over the 100Base-TX physical layer. Twelve user-assignable digital inputs accept signals at 24 V, 3 mA, letting standard PLC transistor outputs provide enable, homing, or limit functions. A relay contact rated at 24 VDC and 1 A can energize brakes or interlock valves, and because the unit does not include integrated safety technology, external STO chains are still required.

Analog resources cover both reference generation and sensor feedback. The base channel can source 5 V at 1 mA to excite potentiometers or resolver converters. The MA1 module extends capability with two ±10 V inputs and two matching ±10 V outputs, and each path is processed at 12-bit resolution to support fine torque or pressure loops. Secondary encoder handling uses EnDat 2.1, and the board also routes 1 Vpp and 5 V TTL signals for mixed incremental and absolute operation. Parameter access is also available through the RS232 serial interface for remote setup.
