Product Description:

The CDB01.1C-ET-ENS-ENS-ENS-ENS-S2-S-NN-FW is a pluggable control unit manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Installed on an IndraDrive stack, it supplies the processing, network, and I/O resources required to regulate servo axes in automated packaging, handling, and machining equipment. By bridging encoder feedback, local I/O, and upper-level PLC networks, the module orchestrates precise current, speed, and position loops while allowing application software to adjust motion parameters in real time.

Network connectivity is centered on a Multi-Ethernet port wired through an RJ-45, 8-pin socket; the hardware supports 100Base-TX (IEEE 802.3u) signaling and automatically selects SERCOS III, EtherCAT, or PROFINET to match the host controller. For process feedback or drive-to-PLC handshaking, the unit offers an analog output channel that can source 0 to +5 V / 0 to +1 mA signals. Its onboard digital I/O section is powered from DC 19 to 30 V and may draw up to 1.1 A, providing fast reaction points for sensors or actuators without external conditioning. These resources let the drive communicate deterministic command words while simultaneously issuing analog references to legacy subsystems.

The ENS encoder block completes local motion capture. Each of the four sockets delivers 12-bit conversion accuracy, accepts differential TTL streams up to 400 kHz, and is supplied with 11.6 V at 500 mA to energize encoder electronics. For service or diagnostics, the integrated RS-232 channel reaches 115 kBaud. Safety wiring is handled by the S2 connector, a 9-pin female D-Sub that presents opto-isolated inputs rated 24 V / 3 mA, transistor outputs at 24 V / 0.5 A, and a relay contact rated at 24 V / 1 A. Together these features allow the card to gather high-speed position data, provide a low-level service console, and participate in hardwired emergency stop chains without additional modules.
