Product Description:

The CDB01.1C-PB-EN1-EN1-NNN-MEM-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CDB Control Units series. It is a plug-in module that mounts on an IndraDrive power section to form a complete drive controller for multi-axis machinery. By managing feedback, fieldbus traffic, and safety signals, the unit coordinates motion sequences and exchanges real-time status data with higher-level automation platforms. Because the control section plugs directly into the power section, drive electronics and interface functions remain in one coordinated assembly. That arrangement lets the unit handle motion control functions without requiring a separate standalone controller at the drive level. It supports deterministic position loops for tasks such as packaging, handling, and printing systems.

The module is designed for 2 synchronized axes, each monitored through 2 x EN1 encoder ports. PROFIBUS is the primary fieldbus, and the channel is routed through a D-Sub 9-pin female connector for straightforward panel wiring. For service or diagnostics, an RS232 port is available, and it supports a maximum rate of 115 kBaud. The control can generate position emulation signals in incremental or SSI formats. These signals can be transmitted over up to 40 m of cable, and edge reproduction is maintained up to 1 MHz. Incoming sensor lines terminate on a D-Sub 15-pin female connector that accepts resolver or HSF feedback, allowing direct linkage to PLC motion blocks and accurate position capture. This layout separates fieldbus, service, and feedback connections across dedicated interfaces.

For HSF transducers, the control unit delivers 250 mA at a stabilized 8 VDC, ensuring sufficient carrier power for high-speed feedback loops. Resolver channels are energized with a 4 kHz excitation to maintain signal integrity across varied cable lengths. Machine safety is integrated through Safety Technology I/O, and the platform exposes this function through a D-Sub 9-pin female safety connector. This arrangement removes the need for external relays and keeps safety wiring easier to organize.
