Product Description:
Bosch manufactures the KDA 2.1-100-3-DQS-W1 Spindle Drive that is optimized for precision-driven manufacturing applications. The drive operates with a DC supply voltage of 300 V and supports a continuous duty current of 35 A for consistent and reliable power delivery. Its enclosure rating of IP10 provides protection against solid foreign objects suitable for typical industrial environments
The KDA 2.1-100-3-DQS-W1 Spindle Drive operates using a forced cooling system. The product has a heatsink blower for thermal regulation. The heatsink blower is powered by a 220 V AC supply. The cooling is achieved by a blower operating at either 50 or 60 Hz which ensures effective heat dissipation during continuous operation. It ensures stable drive function during extended operation. The spindle drive supports a rated current of 100 A. It is built for high-duty applications in machining environments. The product has a digital 16-bit parallel speed command interface. This interface enables precise and rapid speed control. The drive includes a serial interface RS-232C for connectivity. It has strong compatibility for communication-based configurations. The unit provides an auxiliary encoder input for 1V sinusoidal encoders. This feature ensures enhanced feedback for positioning accuracy. It operates efficiently within a temperature range of +5 to +45 degrees Celsius and can withstand storage and transportation temperatures from -30 to +85 degrees Celsius.
The installation altitude of the KDA 2.1-100-3-DQS-W1 Spindle Drive should not be higher than 1000 meters in order to preserve peak performance and avoid overheating. The drive conforms to humidity class F according to DIN 40040 which guarantees insulation reliability in humid industrial conditions. Its design is classified as type 1.
