Product Description:
The KDA 2.1-100-3-L0D-U1 is a high-performance Bosch Rexroth Indramat variant representing a famous KDA Spindle Drives range. This drive controller is designed mainly for single-axis spindle systems. It also delivers a rated current of 100A, providing strong torque support for demanding operations. Mono-axis operation further simplifies system architecture and minimizes potential electromagnetic interference. The unit features a SERCOS interface for live digital communication, allowing precise coordination with the system controller.
Forced air cooling through internal ventilation maintains thermal stability during extended high-current use. It accepts a three-phase input voltage of 230/400 V AC, supporting a wide range of global industrial power supplies without the need for additional transformers. Compatibility with both 50 Hz and 60 Hz input frequencies makes it suitable for international applications. The motor’s design is tailored to meet industrial performance standards with accurate control, thermal reliability and flexible integration. This model supports efficient spindle regulation in environments requiring precise, consistent power delivery and responsive digital feedback.
Power continuity guarantees uninterrupted drive performance under sustained loads which improves process reliability. Global IP20 protection rating shields internal mechanisms from accidental contact and increases operator safety. Operating temperature maintains from 0°C to +55°C sustains functionality in standard industrial environments to prevent thermal shutdowns. The model’s compact dimensions of 390 × 110 × 205 mm reduce cabinet space usage that allows tighter system integration. A mass of about 10.5 kg balances solid build with manageable mounting effort which eases installation in control enclosures. KDA 2.1-100-3-L0D-U1 further supports a 300 V DC bus voltage which stabilizes inverter energy flow and enhances efficiency. Also, its integrated diagnostics monitor drive status continuously and allows rapid fault identification and reduces downtime.
