Product Description:

The CDB01.1C-SE-EN1-EN2-EN2-EN2-S1-S-NN-FW is a modular control unit produced by Bosch Rexroth Indramat within the CDB Control Units series. Designed for multi-axis drive packages, it coordinates power sections and field devices so automated machinery can execute precise motion profiles. It serves as the central control layer between the drive hardware and connected feedback devices, allowing motion commands and machine responses to remain synchronized during operation. This arrangement supports applications that require coordinated axis behavior, reliable signal exchange, and consistent control of connected peripherals.

Inside the unit, a 32-bit processor handles motion sequences for 2 axes while exchanging real-time setpoints over SERCOS II fiber rings. The control electronics draw just 9 W, so cabinet heat is minimal. Each transistorized digital output can source 500 mA per channel, and the integrated I/O rail supplies 1.1 A across sensors and actuators. A single-line display on the front panel gives parameter access and fault codes. Two independent encoder buses are provided; the first delivers 8 V for analog sinusoidal feedback and the second supplies 5 V for incremental TTL devices. When both encoder rails and field I/O are energized, the group output current reaches 1000 mA, allowing external scales and reference switches to remain powered without an auxiliary supply.

During power-up the supply sees a 6 A inrush that is internally limited to a 60 ms pulse, avoiding nuisance trips on upstream breakers. High-speed synchronization tasks are aided by probe channels that capture edges as short as 4 µs, so registration marks on moving webs can be latched without delay. For brake release or contactor drive, the onboard relay is rated at 24 V / 1 A, and the safe-torque-off circuit provides a controlled output of 0.5 A to disable power stages when the safety logic is wired through the D-Sub 9 connector and detects a 24 V, 3 mA enabling signal. These functions give the control unit the signal handling needed for coordinated motion, safety interlocking, and stable interface operation within a multi-axis system.
