Product Description:
The industrial controller CDB01.1C-SE-ENS-ENS-EN2-MA1-S2-S-NN-FW is produced by Bosch Rexroth Indramat within the CDB Control Units series. It is a compact dual-axis control card that plugs into Rexroth power sections and coordinates servomotor movement in automated production lines. The card converts high-level commands from a PLC into precise position, velocity, and torque references, while simultaneously processing encoder signals so the attached drives maintain tight positional accuracy during synchronous or interpolated motion.
Axis control on this model is limited to 2 axes, each supervised through the real-time SERCOS II fiber-optic ring that carries setpoints, diagnostics, and drive parameter data. During idle operation the electronics draw only 9 W, which keeps cabinet temperature low, yet power-up demands are higher; an inrush of 6 A lasting 60 ms must be supplied by the control-voltage source. The board exposes two feedback sockets for 12 V ENS encoders and one for 5 V EN2 devices, identified collectively as 2× ENS and 1× EN2. These interfaces let the unit accept incremental or absolute position data without external adapters, ensuring closed-loop accuracy.
User I/O is handled through the MA1 option card. Two differential analog inputs operate on a ±10 V bipolar window, and two analog outputs share the same ±10 V range; all channels resolve motion commands at 12-bit resolution. Discrete outputs are arranged so that a group can source up to 1000 mA, while any single point is limited to 500 mA. The EN2 connector furnishes 5 V for TTL encoders, whereas each ENS port supplies 12 V for higher-power sensors. Integrated support for Safe Motion provides certified stop, speed, and position monitoring directly inside the control unit.
