Product Description:
Bosch Indramat is a trusted name in drive technology. The product KDA 3.2-050-3-LQD-U1 Spindle Drive is designed for efficient and precise industrial operations. This drive belongs to the series 3 with design type 2 for standard integration. The drive conforms to humidity class F per DIN 40040 for reliability under moderate humidity conditions.
The KDA 3.2-050-3-LQD-U1 Spindle Drive has a 300 Volt direct current bus voltage rating which confirms a steady supply of energy for all spindle operations. The spindle drive receives speed command input via the SERCOS interface for high-speed communication. It also features a digital 16-bit parallel interface for position command input that supports accurate signal transmission. This spindle drive uses forced cooling with a heatsink blower to maintain thermal stability under load. The AC supply for the heatsink blower is 115V which is suitable for industrial environments. The frequency range supported is 50 to 60 Hz which ensures flexible operation across different power systems. The blower unit mass is 4.2 kg while the mechanical mounting kit weighs 1.7 kg for mounting purposes that allow manageable handling during installation. The operating temperature range is +5 to +45 °C which makes it suitable for standard workshop conditions. For accurate feedback control, it has an additional encoder input for a 1V sinusoidal encoder.
The KDA 3.2-050-3-LQD-U1 Spindle Drive can be safely transported within a temperature range of -30 to +85 °C. For accurate performance, it can handle a constant running current of 50 A. The installation height limit is 1000 m above sea level which matches general industrial placement norms. With protection class IP10, it is intended for installation in enclosed control cabinets.
Frequently Asked Questions about KDA 3.2-050-3-LQD-U1:
Q: How does the SERCOS interface improve spindle drive performance?
