Product Description:

The CDB01.1C-SE-ENS-EN2-NNN-NNN-L1-S-NN-FW is a plug-in control unit manufactured by Bosch Rexroth Indramat for the CDB Control Units series. It installs into an IndraDrive power section to handle motion calculations, feedback evaluation, and drive coordination inside automated machinery. By combining encoder interfaces, analog conditioning, serial communication, and deterministic fieldbus traffic, the card links servo drives to a supervisory PLC and keeps axis position, speed, and diagnostics synchronized during operation. This arrangement lets the drive process command references and return operating data without requiring separate interface cards.

The module carries 1 analog input that can accept a ±10 V speed, torque, or process reference, and it reproduces measured values through 2 analog outputs. This supports integration with external monitoring devices and analog control hardware already present in the cabinet. Each analog output has a resolution of 19.5 mV/inc, providing fine voltage steps for external meters or analog PLC channels. For host diagnostics or parameter transfer, the onboard serial port communicates at up to 115 kBaud. Real-time multi-axis coordination is managed over SERCOS II, allowing setpoints, actual values, and status words to circulate on a fiber ring with cycle times suited to high-speed positioning. Software scaling aligns the analog range with connected transducers without extra modules.

Encoder handling is divided between an ENS channel for axis 1 and an EN2 channel for axis 2. This separation allows the primary feedback path and the secondary encoder connection to be processed independently within the drive. The EN2 port provides up to 350 mA at 5.0 V to power incremental encoders. The ENS track accepts TTL feedback signals up to 400 kHz and is supported by its own 11.6 V supply. A dedicated safety relay implements Starting Lockout, ensuring the drive remains disabled after an emergency stop until an explicit enable sequence is received.
