Product Description:

The CDB01.1C-SE-EN2-EN2-NNN-NNN-L2-S-NN-FW is a drive control module produced by Bosch Rexroth Indramat within the CDB Control Units series. It is installed in inverter racks to coordinate multiple servo drives, executing set-point calculation, feedback processing, and fieldbus exchange for industrial automation cells. By combining motion logic, safety input handling, and encoder evaluation in one compact card, the unit streamlines cabinet wiring and supports decentralized axis control in packaging, printing, and material-handling machines.

This model supervises 2 motion axes and exchanges real-time data with the drive bus through SERCOS II; the optical ring operates at up to 16 MBaud, so velocity and position commands reach the inverters within microseconds. The board provides an analog velocity trim of 5 V / 1 mA for applications that still need proportional references from external PLC cards. Discrete machine states are sampled by a digital input block rated at 24 V / 3 mA, allowing direct connection of limit switches or guard contacts without additional interface relays. Status flags such as drive ready or fault are forwarded to higher-level controllers through a transistorized sink/source channel that supports 24 V signaling.

A separate output stage can energize actuators up to 24 V / 0.5 A, and emergency shutdown is integrated through the certified Safe Torque Off function, which interrupts gate signals without affecting feedback power. Dual feedback sockets accept motors equipped with EnDat 2.1 / 1 Vpp / 5 V TTL encoders, and a stabilized 5 V supply is provided for the sensors. A laptop can connect through the on-board RS232 port for parameter access, while STO control and acknowledgment lines rated at 24 V / 3 mA and 24 V DC / 1 A are routed through the nine-pin D-Sub safety connector. A standard membrane operator panel attaches to the card’s front edge for local parameter entry, and an additional relay output rated at 24 V DC / 1 A can be assigned as a fault annunciator.
