Product Description:
The KDA 3.2-050-3-DQI-W1 is a force-cooled drive designed to optimize spindle applications. It provides dynamic control of spindle behavior, allowing rapid adaptation to changing load demands and speed requirements. This responsiveness ensures that machining operations remain consistent even under variable cutting conditions, reducing vibration and improving overall machining smoothness. This drive is designed for compatibility with Bosch Rexroth 2AD asynchronous motors and 1MB frameless spindle motors. This pairing allows the drive to be integrated into a wide range of spindle setups, from standard asynchronous motor-driven spindles to compact, frameless spindle designs used in high-precision applications.
The KDA 3.2-050-3-DQI-W1 is rated for 50 A, giving it the electrical capacity to manage intensive spindle drive demands without compromising stability. In practice, this current rating ensures that the drive can support rapid changes in spindle speed and torque, which is critical when machining cycles shift quickly between roughing passes and finishing operations. Unlike lower-rated drives that may struggle under fluctuating loads, the 50 A capacity provides the headroom needed for consistent response, even during demanding production runs. For reliable operation the drive requires a 300 V input from the DC bus voltage.
The KDA 3.2-050-3-DQI-W1 relies on a 220 V AC supply at 50 to 60 Hz to run its heatsink blower, which powers the forced cooling system. This separate power source makes sure the blower pushes steady airflow over the heatsink keeping temperatures safe while in use. By tapping into a common industrial voltage, the blower fits into typical facility power setups making installation simpler. This drive is suited for operation in conditions that fall between the +5° to +45° C range and humidity levels not exceeding 70%.
