Product Description:
Bosch Rexroth built KDA 2.1-050-3-LY0-U1 which belongs to the KDA Spindle Drives series. This Digital Servo Drive designed for direct spindle control and closed loop regulation that keeps speed steady under variable load. Power supply voltage 3 x 220-230/400-460V AC gives broad compatibility with standard 3-phase plant supplies, lowering the need for special converters. The module with a rated output current 50 A defines the continuous current capability and sets the electrical limit used to size cabling and overcurrent protection.
Power frequency of 50/60 Hz supports operation on global mains grids and permits consistent control timing across regions. Single axis signals for the module provide a single spindle channel, simplifying cabinet layout for single spindle machines. Its air-cool mechanism lets the module shed heat via forced airflow which supports continuous operation within rated limits. Utilizing a fieldbus SERCOS interface enables deterministic digital communication for high resolution speed commands and synchronous integration with CNC systems. This control unit compatibility with Indramat DDS, CLM, DLC controller cards allows direct integration into established Indramat drive systems and standardizes commissioning procedures.
Type code KDA 2.1-050-3-LY0-U1 mounts for control cabinet mounting which places the module inside protected electrical enclosures and eases wiring to incoming mains and controllers. International protection certification of IP 10 (without additional enclosure) indicates basic protection against contact and larger particles so the module requires a cabinet for environmental protection. Permitted ambient temperature 0°C to 45°C (operation) defines the allowable operating range to maintain thermal performance and component reliability. Weight approx. 18 kg informs mechanical handling and cabinet support design. The unit with maximum continuous current 50 A specifies the sustained current rating and guides thermal and protection system design.
Frequently Asked Questions about KDA 2.1-050-3-LY0-U1:
Q: Why is the rated output current important for KDA 2.1-050-3-LY0-U1?
A: The rated output current 50 A sets the continuous current limit available to the spindle motor. This rating determines conductor sizing and the rating for thermal protection components.
Q: How does power frequency impact operation of KDA 2.1-050-3-LY0-U1 drive?
A: The power frequency of 50/60 Hz establishes the mains frequency the module is rated to operate along with influences timing reference and synchronous interface behavior.
Q: What does the number of axis show about the KDA 2.1-050-3-LY0-U1 motor?
A: The number of axis as “1” (single axis) states that the drive provides one independent spindle channel. This detail affects system partitioning and cabinet space planning.
Q: Why does the fieldbus type relevant for KDA 2.1-050-3-LY0-U1?
A: The fieldbus SERCOS interface specifies the deterministic communication protocol used for command and feedback. It also defines compatibility with compatible CNC and automation systems.
Q: How does the cooling method influence KDA 2.1-050-3-LY0-U1 performance?
A: The air-cooled mechanism identifies the thermal removal approach used by the module. This requirement impacts cabinet ventilation design and ambient airflow management.
