Product Description:
The KDA 3.2-100-3-D0D-W1 is produced by Bosch Rexroth Indramat within the KDA Spindle Drives series. As a dedicated spindle drive, it interfaces with CNC control systems to regulate the speed and torque behavior of high-speed spindle motors used in machining centers and similar automated equipment. The unit is part of Series 3 with version 2 hardware, which identifies its revision level within the product line and helps distinguish it from other KDA drive variants.
The internal blower operates from an AC source of 220 V at 50–60 Hz, so the cooling circuit can be supplied from a standard single-phase cabinet connection. The power section is energized by a DC bus of 300 VDC, and it can deliver a continuous output of 100 A to the spindle motor. Heat generated under load is removed by a heatsink-mounted blower, and the drive uses forced cooling to maintain a stable internal temperature during extended operating periods. Speed reference data is provided through a 16-bit parallel digital signal, giving the controller fine command resolution across the operating range. The drive does not include a second encoder input, so it is intended for applications that do not require that additional feedback channel.
Ambient installation limits are 5 to 45 °C, allowing operation in typical industrial settings when adequate enclosure ventilation is available. The hardware can be mounted at elevations up to 1000 m above sea level before additional thermal measures are needed. For coordinated axis movement, the unit supports a digital position command interface that lets the control system send absolute position targets directly to the power stage. This signal path complements the primary speed channel and supports applications where spindle motion must follow commanded positioning profiles as well as speed setpoints.
