Product Description:
The KDA 2.1-050-3-DQD-U1 spindle drive is produced by Bosch Rexroth Indramat and belongs to the KDA Spindle Drives series. Designed for high-speed machining axes, the unit acts as a power stage that converts numerical control commands into regulated three-phase output for an induction or synchronous spindle motor. It supplies the torque, speed regulation, and positional response needed for milling, turning, and grinding operations. The drive is intended for installation in machine-tool cabinets where the power stage, motor leads, and control wiring operate as part of a coordinated motion system.
It draws a continuous current of 50 A from a shared intermediate circuit held at 300 VDC. Thermal management is handled by a mounted heat-sink blower whose fan motor is powered by a dedicated 115 V/50–60 Hz supply. This arrangement works with forced cooling to keep the power semiconductors within their allowable operating temperature during repeated acceleration and deceleration. Digital control is standard, and the unit accepts a parallel speed word together with a separate position command interface for coordinated spindle control. This control structure lets the drive respond quickly to changing spindle commands during cutting and rapid speed transitions.
The permissible ambient range is 5 to 45 °C, so inlet air in the cabinet must stay within that interval during operation. Installation is supported up to 1000 m above sea level without output derating under the stated conditions. Adequate ventilation space around the heat sink helps maintain stable thermal performance during continuous spindle duty. Command processing uses a digital 16-bit parallel speed word, and axis positioning can be refined through a digital position command input. The separate speed and position channels support synchronized spindle behavior during interpolated moves and other coordinated machining sequences.
