Product Description:

The KDA 3.1-100-3-L0I-W1 is a spindle drive from Bosch Rexroth Indramat's KDA Spindle Drives line. It is meant to provide a rated output current of 100 Arms. It can work with both resolver and encoder feedback, therefore it may be used for a wide range of motor control needs in modern machine tool applications. This drive needs a three-phase 400/480 V AC power source and uses air to cool itself. In harsher circumstances, users may add a fan unit to make it even cooler. The device weighs around 8 kilograms and is designed to be mounted on a panel within a control enclosure. To properly install the KDA 3.1-100-3-L0I-W1, users need to follow a methodical process.

They need the M1-KD mechanical accessories kit, the LE4-...V blower unit, and the KDA 3 drive to install it. As stated in the product description, the back panel of the control enclosure has to have the right vents and drilled holes. The unit also needs to be put vertically so that air can circulate and cool it properly. First, the mounting panel from the M1-KD kit is attached to the rear panel of the control enclosure using screws. The KDA 3.2 frame is attached to the outside of the enclosure and is held in place from the inside. This provides a sturdy, level surface for the drive's flat gasket.

With its built-in windings and sealing rings, this frame makes sure that the unit is securely installed and sealed properly between the unit and the control cabinet. The mounting frame for the heatsink blower is also connected to the rear panel of the control enclosure. The air duct is then screwed into the KDA's mounting frame from behind, finishing the configuration of the cooling system.
