Product Description:

The CDB01.1C-PB-ENS-ENS-EN1-EN1-L2-S-NN-FW is a modular dual-axis control section manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Installed on a compatible power module, it processes command data, generates PWM gate signals, and manages feedback from multiple encoder channels. By handling interpolation, parameter storage, and network messaging inside the controller cabinet, the unit positions servo motors with millisecond accuracy and relays diagnostic states to a supervisory PLC in applications such as pick-and-place gantries, form-fill-seal machines, and automatic storage systems.

Analog outputs are rated at 5 V / 1 mA, so external gauges or test points can be driven without overloading the low-power DAC stage. Digital inputs expect 24 V / 3 mA; this current threshold matches standard industrial sensor outputs and ensures reliable logic state recognition. Field communication is accomplished through PROFIBUS, allowing cyclic data exchange and parameter access across a multi-drive network. Internal electronics draw only 9 W from the DC bus during standby, leaving most cabinet power budget for the power stage. Up to 1.1 A of auxiliary current is available on the I/O rail to feed prox switches, light curtains, or relay coils connected directly to the board.

An integrated serial port supports up to 115 kBaud over the MiniDIN connector and can be accessed with standard RS232 cables. The motion core simultaneously coordinates 2 axes while resolving position feedback from IndraDyn, HIPERFACE, or legacy MHD/MKD encoders. A dedicated D-Sub socket links to external safety relays, and the certified Safe Torque Off function removes drive-enable signals within microseconds when the safety channel opens. These interface options, combined with consistent encoder handling and high-speed diagnostics, allow the control section to integrate into complex machines without additional gateway cards.
