Product Description:

The KDA 3.1-050-3-AQI-W1 spindle drive operates to keep the motors and drives parameters running with regulated speed and position. It is manufactured by Bosch and its designs perform well with accurate outputs in industrial automation.

The KDA 3.1-050-3-AQI-W1 spindle drive is a 3-phase AC supply source with a heatsink blower. The input voltage allowed to the drive is rated at 220 V which works with the normal industrial power supply. This auxiliary encoder input enables the system to access 1V sinusoidal encoders to support accurate feedback and positioning applications which are often used in motion control platforms. This aspect helps improve the accuracy of the system's monitoring without adding more converters. Its installation height reaches an altitude of 1000 meters above sea level and it also has a smooth performance without the altitude change. The permitted water percentage content is based on the provisions of DIN 40 040 which guarantees the operational uniformity in the specified environmental conditions. To provide protection to it, it is protected with IP10 to provide general safety against accidental contact with water.

The KDA 3.1-050-3-AQI-W1 spindle drive is able to offer an incremental encoder output along the auxiliary interface. This will allow simple communication between the controller and the motion hardware and give ease in synchronization. It uses a feature of cooling that is enclosed with a forced-cooled heatsink blower. This cooling solution benefits to ensure maximum thermal levels which makes it possible to operate continuously in harsh environments without thermal cutoffs or performance degradations. Its unit has a DC bus voltage that is standard at 300 V based on widespread industrial drive system needs.
