Product Description:
Bosch Rexroth Indramat manufactures the KDA 3.2-150-3-LP0-W1 spindle drive, placing it in the KDA Spindle Drives series used for high-speed machining centers and turning equipment. This unit is Series 3 and Version 2. It acts as the power and control stage between the DC bus of a supply module and a synchronous or induction spindle motor, converting command data from the automation controller into regulated current and velocity. Within an integrated motion platform, it enables accurate spindle acceleration, positioning, and surface-speed regulation during cutting or grinding cycles.
The drive’s power section is energized by a regulated link voltage of 300 VDC, and its inverter can source up to 150 A of continuous current, giving adequate torque for large-frame spindles. Thermal performance is protected by forced cooling that draws air across the power semiconductors through a mounted heat sink blower. The blower is supplied from a separate circuit rated at 220 V/50-60 Hz. By keeping the heat sink within its operating range, the unit can sustain rated output during prolonged heavy cuts, and internal electronics monitor blower status to trigger a fault if airflow is lost.
Velocity setpoints arrive over the SERCOS interface, so the drive fits into fiber-optic motion networks without analog scaling errors. It maintains full ratings when the cabinet air stays within 5 to 45 °C and the machine is installed no higher than 1000 m above sea level; derating applies beyond these limits. A dedicated second encoder port supports spindle-synchronous feedback or an auxiliary motor encoder, and the hardware is streamlined without an additional interface option. The second encoder connection supports applications that require synchronized spindle feedback during orienting, threading, or contouring moves.
