Product Description:
The KDA 3.1-150-3-LQD-W1 Spindle Drive features an auxiliary encoder input which accommodates a 1V sinusoidal encoder for precise spindle position feedback. With a rated current capacity of 150 A, this spindle drive can handle demanding spindle motor operations and provide consistent performance.
The operation of this KDA 3.1-150-3-LQD-W1 drive is provided with a DC link voltage of 300 V, which delivers the electrical stability needed for continuous operations. Its forced airflow cooling through a heatsink fan offers effective thermal control to maintain high output ratings in prolonged production runs. Its auxiliary interface is optimized for processing position command values in a digital 16-bit parallel format, ensuring interference-free and fast communication with the control system. Its electrical connection to NC terminals is through an X2, 37-pin connector to give a secure and standardized interface for integration into CNC control architectures. With a protection grade of IP 10 per DIN 40050, this drive needs to be installed where no excessive dust and debris are present. Its heatsink fan is powered at 220V using 50-60 Hz to provide consistent airflow for temperature regulation and guarding sensitive components from thermal stress. With a fan assembly mass of 4.2 kg, its mechanical stiffness is assured while maintaining consistent cooling performance over long use.
The mounting accessories of the KDA 3.1-150-3-LQD-W1 drive weigh 1.7 kg for firm support while minimizing vibration as it is fitted into a control cabinet. Its operating temperature range of +5 to +45 °C ensures reliable performance over typical manufacturing facilities without overheating threat. The shipping temperature range of the KDA 3.1-150-3-LQD-W1 drive is -30 to +85 °C, which enables transportation or storage in diverse climates. Its moisture rating F, according to DIN 40 040, provides insulation against environmental humidity under non-operating storage conditions.
