Internal Product Review
The CDB01.1C-ET-EN1-EN2-NNN-NNN-L1-S-NN-FW is a Bosch Rexroth Indramat control unit built for 2-axis motion systems with Multi-Ethernet communication. The EN1 resolver/HSF input and EN2 support for EnDat 2.1, 1 Vpp, and 5 V TTL provide excellent feedback flexibility for mixed servo configurations. Starting Lockout with Category 0 stop adds a well-engineered safety layer and rounds out a highly capable control platform.

Product Description:
The CDB01.1C-ET-EN1-EN2-NNN-NNN-L1-S-NN-FW is a double-axis control section produced by Bosch Rexroth Indramat as part of the CDB Control Units series. It is designed for mounting in IndraDrive power sections, where it receives fieldbus commands from a higher-level machine control system. The module evaluates encoder feedback and issues pulse-width modulated gate signals so connected drives can follow reference profiles in assembly lines and packaging machines.
Internally, the unit processes motion commands for 2 axes and exchanges data through the Multi-Ethernet interface, which supports real-time EtherNet/IP, PROFINET, and EtherCAT telegrams for integration with different automation networks. Continuous controller logic requires only 9 W of base power, which helps keep cabinet heat rise low during continuous operation. During startup, the DC link must tolerate an inrush of 6 A for about 60 ms. Six digital inputs are galvanically isolated and accept signals at 24 V, 3 mA, and these inputs can be assigned to homing, limit, or drive-enable functions. Supplemental plug-in boards provide the EN1 and EN2 channels with 6 W each, while the ET communication plug draws 2.2 W and the L1 encoder supply consumes 2 W to support the installed interface options. A front RS232 port is included for local service access and configuration, and the primary resolver/HSF interface supplies excitation voltage for analog feedback devices.
Two solid-state relay contacts can switch up to DC 24 V, 1 A for status lamps or external interlocks. The second feedback port handles EnDat 2.1, 1 Vpp, 5 V TTL signals, allowing high-resolution position control without additional converters. Personnel protection is supported through the dedicated safety input that provides the Starting Lockout function, keeping the power stages disabled until risk mitigation criteria are met. When an emergency halt is raised, the unit performs a controlled mains removal in compliance with Category 0 stopping, which immediately eliminates torque without dynamic braking. This combination supports external status signaling and direct connection of high-resolution feedback devices on the same control section.
