Product Description:

The CDB01.1C-SE-ENS-ENS-NNN-MA1-S2-S-NN-FW is a control unit manufactured by Bosch Rexroth Indramat as part of the CDB Control Units series. Designed for IndraDrive drives, it provides axis control, fieldbus communication, and integrated safety functions for industrial machinery. By processing motion commands at the drive level, the card translates high-level instructions into real-time current, velocity, and position targets for precise coordination in packaging, printing, and material-handling stations. It installs in the power section stack and connects internally through the backplane, which helps reduce cabinet wiring.

The board manages 2 motion channels, each synchronized over the SERCOS II optical ring so update times remain deterministic at high production speeds. Its configurable digital outputs can sink or source up to 500 mA, which is sufficient for brake coils or status lamps, while the combined peripheral rail supplies a maximum of 1.1 A to external sensors and actuators. Feedback enters through the ENS interface, allowing connection of inductive or optical encoders without additional converter cards. Integral Safe Motion hardware continuously verifies speed, direction, and standstill, and it disengages torque if set limits are exceeded.

The ENS channel digitizes position data with 12-bit granularity and maintains fidelity up to 500 kHz, helped by a differential input resistance of 120 ohms that reduces line reflections. The encoder rail is energized at 11.6 V DC, so the system power supply must remain within tolerance to avoid checksum faults. Supplemental I/O arrives through the MA1 module, bringing two 12-bit analog inputs and two 12-bit outputs for process control tasks such as pressure regulation or tension trim. A form-C relay rated at 24 V DC and 1 A permits direct switching of brakes, contactors, or signal beacons.
