Product Description:

KDA 3.2-050-3-DQ0-U1 is a top model from Indramat high performance KDA Spindle Drives family. Its continuous output current of 3.2 A provides precise with less power spindle actuation. The component’s peak output current reaching 6 A permits handling short transient loads. The supply voltage rated at 3 × 230/400 V AC (±10 percent) enables compatibility with diverse three-phase industrial power networks.

Rated power of 0.5 kW> for the equipment allows modest drive capability for light spindle operations. Cooling using natural convection removes heat without external fans, thus reducing maintenance. Its control type, designated as digital, further supports precise control algorithms. The drive employs a communication interface via serial RS232 or RS485 offers robust compatibility with industrial controllers. < safety rating prevents ingress of solid objects larger than 12 mm and hence improving safety in enclosed environments. The inclusion of panel mounting allows direct integration into control panels. Mass of approximately 8.5 kg facilitates manual handling and cabinet stability.

Model KDA 3.2-050-3-DQ0-U1 introduces compact form integration with its dimensions of 390 × 160 × 250 mm allowing spatial efficiency in cabinet layouts. Feedback is supported through incremental encoder which enables live positional tracking of spindle rotation. The single axis configuration streamlines wiring and mechanical coupling, thus simplifies single-axis applications. Drive’s cooling by natural convection process eliminates auxiliary cooling systems and also reduces complexity. Moreover, it operates with a DC bus voltage of 300 V, ensuring stable and efficient power delivery across varied load profiles. As the model relies on natural convection, so multiple variants in the KDA range employ forced cooling via heatsink blower for increased thermal management.
