Product Description:

Bosch Indramat manufactures the KDA 3.2-100-3-L0S-U1 Spindle Drive engineered for industrial spindle control applications. It is intended to operate at temperatures between +5 and +55 °C. It can also endure a storage temperature of -30 to +85 °C without damage. The unit is built for humidity class F for reliable functioning in industrial conditions.

The KDA 3.2-100-3-L0S-U1 Spindle Drive operates with a Speed Command Value SERCOS-Interface for precise speed regulation. This model, which is part of the Drive Series 3, has drive design 2 for reliable and steady operation. It can manage demanding load needs by delivering a rated current of 100 A. The unit is built with protection class IP10 for operation in controlled indoor environments. It includes an auxiliary interface RS-232C for monitoring and communication purposes. The drive runs on a direct current bus voltage of 300 V to maintain reliable power delivery. For installation, the mounting type mechanical accessories kit M1-KD is provided, with a mechanical accessories kit M1-KD weighing 1.7 kg for convenient handling. The overall drive weight of 17.1 kg ensures durability while remaining manageable for installation. The KDA 3.2-100-3-L0S-U1 Spindle Drive maintains performance within its designated electrical and environmental constraints by combining accurate control, effective cooling and robust construction.

A 1000-meter installation elevation is supported by the KDA 3.2-100-3-L0S-U1 Spindle Drive without compromising performance. A heatsink blower to control heat while operating continuously can be used for cooling purposes. The blower unit 4.2 kg operates within a frequency range for the heatsink of 50 to 60 Hz. The heatsinks AC power source has a 220 V rating to ensure that it works with conventional electrical systems
