Product description

What to know about KDW1.1-100-300-W1

The KDW1.1-100-300-W1 is an Indramat AC main-spindle drive from the modular 300 VDC drive generation. It is used to regulate spindle speed and torque in CNC and production machinery where the original cabinet remains in service.

The code identifies series 1, design 1, a 100 A class, 300 VDC link and W1 fan-cooling arrangement. Replacement decisions should also account for the motor, feedback, command electronics and any configuration markings on the installed unit.

Litco publishes this exact identifier in its power-system inventory. Send the nameplate and cabinet photos for a shelf match, repair evaluation or compatible replacement discussion.
