Product Description:
The KDA 3.2-100-3-LYI-U1 spindle drive is manufactured by Bosch Rexroth Indramat and belongs to the KDA Spindle Drives series. Positioned in release 3, version 2 of this product line, it links a 300 VDC power bus to a machine-tool spindle and converts the fixed bus into a controlled three-phase output. This allows the unit to support rapid acceleration, brake energy handling, and precise speed holding in automated cutting, drilling, and grinding cells.
Electrically, the drive is supplied by a DC link of 300 VDC and can deliver a continuous phase current of 100 A to the spindle motor. An auxiliary supply of 115 V/50-60 Hz powers the mounted heatsink blower, and this provides the drive’s forced cooling system for removing heat from the semiconductor stack during heavy duty cycles. Internal current sensing and thermal monitoring work with this cooling path to protect the power section against overload, and the arrangement allows the unit to sustain nominal output without derating at the stated ambient limit.
Control and feedback functions are handled through an incremental encoder output for downstream position controllers and a second encoder input for synchronous feedback when dual-loop accuracy is required. Speed references arrive through the SERCOS interface, allowing deterministic updates on a fiber-optic network. The drive operates within an ambient range of 5 to 45 °C and is intended for enclosed machining centers that maintain stable thermal conditions and consistent communication links. Wake Industrial offers a one-year warranty on this KDA 3.2-100-3-LYI-U1 spindle drive. For questions about errors and faults customers can use the free chat tool available on our website.
