Product Description:

The CDB01.1C-ET-ENS-ENS-NNN-NNN-L1-S-NN-FW is a control unit manufactured by Bosch Rexroth Indramat and supplied under the CDB Control Units series. It is mounted on an IndraDrive power section to execute motion logic, network routing, and safety interlocks for servo machinery. Within an automated cell, the module interprets drive commands, exchanges real-time data with higher-level controllers, and conditions encoder feedback signals so that two independent axes can be synchronized without external PLC hardware.

This module processes exactly 2 drive channels and draws only 9 W at idle, which limits cabinet heat during standby. Fieldbus traffic is handled by a Multi-Ethernet interface, and the link follows the 100Base-TX standard so data moves at 100 Mbit/s. A pair of RJ-45 sockets supports line or ring wiring, and the copper segment may run up to 100 m before repeaters are required. During power-up, the unit tolerates an inrush of 6 A for 60 ms, so circuit breakers must be sized to accommodate that pulse. A 24 V / 3 mA start-lockout input provides hardwired restart prevention, while the onboard relay contacts rated at DC 24 V and 1 A can release external brakes or signal a safe-torque-off chain. RS-232 diagnostics are permitted over 15 m of cable for setup and troubleshooting.

On the feedback side, position signals can travel 75 m when shielded sense lines are used, and wiring terminates on a D-Sub 15 Female connector that mates with standard encoder cables. The logic stage supplies encoders with a typical 11.6 V source, which is adequate for IndraDyn S, Hiperface, EnDat 2.1, 1 Vpp, or 5 V TTL transducers. Two network ports permit daisy-chain topologies, and the low base dissipation helps keep enclosure temperatures under control even when both axes run continuously.
