Product Description:
The KDA 3.2-150-3-APD-U1 is a spindle drive unit manufactured by Bosch Rexroth Indramat for the KDA Spindle Drives series. It converts intermediate-circuit power into precisely regulated three-phase output for high-speed machine-tool spindles and similar automation axes. This operating role makes it suitable for applications that require stable torque and speed regulation during demanding motion cycles. Series code 3 and version 2 indicate the product generation used for this drive type.
The power section is energized from a direct-current link rated at 300 VDC, which provides the voltage margin needed for rapid acceleration and regenerative braking. Under continuous operation, the drive can deliver up to 150 A of output current, so it can sustain large torque demands without saturating the control electronics. A dedicated heatsink blower supplied from an auxiliary line of 115 V 50/60 Hz removes semiconductor losses during operation. The cooling mode is forced cooling, so airflow is actively directed through the fin channel rather than relying on cabinet convection. Motion commands enter through a digital position command value interface that transmits step or incremental data, while velocity is adjusted through an analog speed command value input. This arrangement allows position and speed references to be handled through separate channels for coordinated spindle control.
The allowable ambient range is 5–45 °C, which supports installation in typical shop-floor enclosures without auxiliary chillers. Operation is permitted up to 1000 m elevation before output derating may be required. For applications that need rotor-angle tracking or master-slave synchronization, the drive includes a second encoder input. This input can accept either spindle feedback or an additional motor encoder. It allows extra control-loop feedback without requiring an external splitter module.
