Product Description:
The KDA 2.1-050-3-LY0-W1 from Bosch Rexroth with in the KDA spindle drives product range. This drive controller represents the control architecture used for spindle regulation, closed loop monitoring and commissioning workflows for machine tool integration. The current is rated as 50 A for the continuous electrical capability and determines conductor sizing, overcurrent protection selection and thermal expectations for sustained operation. Regulator version "2" defines the regulator generation and influences control loop structure along with available tuning parameters and safety interlock behavior integration. Design "1" identifies the device’s internal layout and further guides rack placement, clearance planning and service access procedures for fault isolation.
With an air-cooled (internal fan), the motor provides forced internal airflow and can maintain component temperatures during extended duty cycles while simplifying cabinet HVAC requirements. Its mains connection voltage displays three-phase, 380-460 V AC which reduces the need for external voltage conversion while enabling wider plant compatibility. Its frequency 50/60 Hz supports global mains systems and also preserves consistent timing for control loops and synchronization needs. Feedback supported "LY0" (resolver feedback) enables resolver based position sensing to supply robust rotor position data for precise closed loop control.
The variant KDA 2.1-050-3-LY0-W1 is compatible with MAC servo motors family and ensures electrical and feedback compatibility for direct drive operation and simplified connector mapping. The protection rating of IP 10 indicates the ingress protection level with mandates use of an enclosure for particles and contact safety in factory environments. Product's weight of around 14 kg provides a physical mass reference and it informs mounting hardware, transport planning and cabinet load calculations. Operating at a permissible temperature range 0°C to +45°C sets environmental limits and safeguards thermal stability and component life under rated use.
