Product Description:

The CDB01.1C-SE-ENS-ENS-ENS-MEM-NN-S-NN-FW belongs to the CDB Control Units series produced by Bosch Rexroth Indramat. This plug-in control card works with IndraDrive power sections to supervise servo loops, manage fieldbus communication, and generate encoder emulation for two drive axes in industrial automation cells such as pick-and-place gantries and printing lines. It acts as the local processor that converts motion commands from the machine controller into current, speed, and position references for the connected drive sections. Because control processing is handled on the card, the associated power sections can focus on motor current delivery while motion logic remains centralized at the drive level.

The board manages 2 axes and exchanges cyclic setpoint and status data through SERCOS II. Its internal electronics are powered by a dedicated DC 24 V control supply and draw a base load of 9 W when the axes are idle. A typical inrush current of 6 A occurs at startup, so the control supply must be able to handle that brief demand without dropping the control voltage. Two analog monitor channels can present process variables up to 5 V, which allows direct observation of signals such as torque, speed, or temperature without requiring additional transducers. That arrangement also provides a simple analog interface for external monitoring equipment.

Each axis provides three encoder inputs for differential ENS signals. The input circuits use 120 ohm impedance, provide a 500 mA sensor supply at DC 11.6 V, and apply filtering at 500 kHz to reduce noise on incoming feedback lines. The MEM generator recreates digital quadrature feedback for legacy CNC or PLC cards at rates up to 1 MHz, and pulse outputs can be extended to 60 ms for low-speed positioning tasks. Integrated safety functions are not included on the card, so any required STO or SS1 functions must be provided by external hardware.
