Product Description:

The CDB01.1C-SE-ENS-ENS-EN2-NNN-S2-S-NN-FW is a dual-axis control section produced by Bosch Rexroth Indramat for the CDB Control Units series. Installed in a modular drive cabinet, the unit coordinates power stage electronics and feedback devices so servo drives follow motion commands issued by an automation controller. It serves as the command core for velocity, current, and position loops in packaging machines, material-handling lines, and general factory automation, where coordinated axes must respond consistently to changing load conditions. Its role centers on control and feedback handling, while the associated power sections deliver motor current for each connected axis.

The control logic draws 24 V DC at only 7.5 W. One differential analog input with 160 kΩ impedance reads process variables, while two analog outputs deliver 1 mA at 5 V. This single input and dual outputs are joined by 18 digital inputs, two touch-probe lines, and one relay output rated at 24 V DC and 1 A; combined sourcing is 0.5 A. Two axes are driven through the SERCOS fiber-optic interface, which exchanges telegrams every 500 µs minimum. Internally, the current loop updates at 125 µs, the speed loop at 250 µs, and the position loop at 500 µs. Encoder ports supply 12 V for ENS transducers and 5 V for EN2 feedback.

Cycle-synchronous features rely on a PWM carrier of 4 kHz and a switching frequency of 8 kHz, enabling smooth torque generation while keeping motor heating low. Installation is simplified by a SERCOS connector that is secured with 0.6 Nm of coupling-nut torque. The integrated safety option, Safe Motion, lets the drive execute certified monitoring functions without external relays. A RS232 port provides local access for setup and diagnostics when operating data must be reviewed at the cabinet. This arrangement supports motion applications that need both coordinated control and integrated safety monitoring within the same drive platform.
