Product Description:
The CDB01.1C-SE-EN1-EN1-EN2-NNN-S2-S-NN-FW is a plug-in control section in the CDB Control Units series manufactured by Bosch Rexroth Indramat. Installed on an IndraDrive power module, it provides the computation and feedback interfaces required to close torque, speed, and position loops for servo axes in automated packaging lines, assembly cells, and material-handling equipment. Its interface set supports common motor feedback types used in IndraDrive systems, so the drive can process encoder and resolver signals directly at the axis. The board also supports Safe Motion functions, allowing the drive to meet performance-level safety requirements without extra hardware.
The analog front end resolves input signals down to 1.23 mV/inc, giving the PLC fine control over motor behavior, while a programmable output can source a stable 5 V process value. Control electronics consume only 9 W from the 24 V cabinet supply, and each digital channel can switch loads up to 24 V / 0.5 A. An integrated EN1 encoder rail delivers 8 V to absolute encoders, and startup circuitry withstands an inrush of 6 A without tripping auxiliary fuses. A separate 5 V EN2 rail powers TTL feedback devices, while resolver sensors are supported by an 18.2 Vpp excitation at 4 kHz. These dedicated supply rails let the control section serve several feedback formats without external interface modules. Two optical SERCOS ports link the unit to the drive bus and support Safe Motion telegrams.
The control section caps individual pulse widths at 60 ms and limits the combined load of a digital output group to 1000 mA to protect PCB traces. Real-time setpoints and diagnostics travel across the SERCOS ring at up to 16 MBaud, maintaining deterministic response for coordinated multi-axis moves. A Form C relay rated at DC 24 V / 1 A can engage brakes or contactors, and resolver feedback is demodulated to reject cable noise. The relay output suits low-current switching tasks on the axis. This helps keep switching behavior predictable during repeated machine cycles.
