Product Description:

The CDB01.1C-ET-EN1-EN1-NNN-MEM-L1-S-NN-FW is a control section from Bosch Rexroth Indramat's CDB Control Units series. Acting as the interface between higher-level motion controllers and IndraDrive power stages, the device coordinates feedback, communication, and diagnostic data for multi-axis machinery in industrial automation systems. Within this role, the CDB01.1C-ET-EN1-EN1-NNN-MEM-L1-S-NN-FW manages encoder inputs, processes Ethernet telegrams, and reports operating status, allowing drives to start, accelerate, and stop at commanded positions without external signal conditioning.

Two independent feedback sockets accept 2 × Resolver/HSF signals, allowing the unit to read primary and auxiliary axes at the same time. For communication with PLCs, the controller relies on Multi-Ethernet, which supports several industrial protocols through a single port. A Single-Line control panel gives access to parameter numbers and fault codes without an external computer. Internal consumption is held to 9 W, so enclosure heat rise stays low and power supply demand remains modest. When the device emulates position data for legacy drives, it delivers pulses at 1 MHz, can shape them up to 60 ms wide, and sends them through cable runs up to 40 m while maintaining SSI or incremental format integrity. The resolver supply provides 18.2 Vpp at 4 kHz, and the HSF reference track is energized with 8 V for clean sine-cosine signals.

During startup, the electronics draw a typical inrush of 6 A before settling to nominal consumption. Network wiring follows the 100Base-TX standard, and cable segments may extend to 100 m without requiring a switch, which matches common plant layouts. A built-in safety mechanism titled Starting Lockout prevents unintended motion by inhibiting drive enable until external safety circuits are cleared. This function keeps the power stage disabled until the external safety chain permits motion.
