Product Description:

The CDB01.1C-S3-NNN-NNN-NNN-NNN-L1-S-K1-FW is a plug-in control section produced by Bosch Rexroth Indramat for mounting on power sections in the CDB Control Units series. Within an IndraDrive system, this module acts as the supervisory logic layer that coordinates motion commands, processes fieldbus data, and distributes I/O signals to connected drives and sensors. It is intended for multi-axis automation tasks where synchronized positioning, speed regulation, and integrated safety functions are required on assembly stations, packaging lines, and handling equipment.

Each control section powers up from a 24 V DC logic supply and draws up to 1.1 A during normal operation, resulting in a heat dissipation of 9 W, so ventilation demands on the cabinet remain modest. Two independent processing channels give the unit an axis count of 2, allowing synchronous interpolation between drives. Real-time motion commands and parameter downloads are exchanged over the SERCOS III fiber-optic ring, while a non-isolated serial port supports local programming. For local actuation, the board provides eight sourcing outputs that can switch loads up to 500 mA each, plus analog outputs that deliver 1 mA or 5 V signals for proportional valves, recorders, or transducers. A maximum output pulse width of 60 ms supports latch or kick functions on pneumatic valves.

System integration options expand through the built-in RS232 maintenance interface, which can stream diagnostic traces at up to 115 kbit/s without occupying the real-time bus. Event capture accuracy is enhanced by a probe channel with a 1 µs response that accepts sensor currents of 3 mA, ensuring precise edge recognition for print mark or registration tasks. During startup, the backplane can experience an inrush current of 6 A, but once steady, relay contacts rated for 1 A at 30 V DC handle field isolation. A Starting Lockout function prevents unintended drive enable until logic prerequisites are met when power or communications are restored.
