CDB01.1C-S3-EN1-EN1-NNN-NNN-NN-S-NN-FW

The Bosch Rexroth Indramat CDB01.1C-S3-EN1-EN1-NNN-NNN-NN-S-NN-FW control unit from the CDB Control Units series is engineered for high-performance drive applications and features Master Communication: SERCOS III for deterministic, real-time data exchange. Manufactured by Bosch Rexroth Indramat, this module integrates an Option 1: Encoder HSF/RSF interface and an Option 2: Encoder HSF/RSF interface, alongside Option 3: Not Equipped slots for future expansions. The compact unit measures 103 x 322.6 x 49.5 mm and is designed to plug directly into the IndraDrive power section.

Reliability is built in with a robust housing rated for up to 20 insertion cycles, ensuring secure mechanical connections during maintenance. Onboard diagnostics are displayed via dual-color LEDs: a yellow LED indicating active data transmission and a green LED confirming network link integrity. The firmware is supplied as a separate subitem, allowing straightforward field updates without modifying the core control board. Cooling recommendations include forced ventilation or an auxiliary fan to maintain optimal operating temperature and prevent thermal derating.

This control section expertly handles Pulse Width Modulation frequency switching between 2 kHz and 16 kHz, enabling precision current control in the 62.5–125 ms window and position control within 250–500 ms cycles. Its modular design, deterministic SERCOS III master communications, and dual encoder interfaces make the CDB01.1C-S3-EN1-EN1-NNN-NNN-NN-S-NN-FW an ideal choice for high-density automation environments seeking seamless integration and long-term reliability.
