Product Description:
Bosch Rexroth Indramat builds the KDA 3.2-050-3-DPD-U1 as part of the KDA Spindle Drives series, generation 3, version 2. Classified as a spindle drive, the module interfaces with CNC controllers to regulate motor torque and velocity. It is intended for automated machining and grinding equipment that requires stable spindle speed profiles during cutting cycles. Because it functions as the control stage between the CNC and the spindle motor, it must respond cleanly to changing load demands during acceleration, deceleration, and constant-speed operation.
The power section operates from a DC link of 300 VDC and delivers a continuous output of 50 A to the connected spindle motor. This output level suits medium-power spindle duties in milling and drilling stations, where continuous current capacity must remain stable during long operating periods. Thermal energy is removed by a mounted heatsink blower, and the drive uses forced cooling to maintain component temperatures under sustained load. The blower is powered from an auxiliary source rated at 115 V/50–60 Hz, allowing cabinet wiring to use a separate utility circuit instead of the main bus. This arrangement helps the cooling hardware operate independently of the motor power path.
The drive is specified for ambient temperatures from 5 to 45 °C and can be installed up to 1000 m above sea level without derating. Speed commands are applied through a 16-bit parallel digital channel, while a separate line accepts a digital position command value so velocity and position loops can be handled independently by the upstream controller. A second encoder socket is available for spindle or auxiliary motor feedback, which supports machine layouts that require added sensor input. That separation can simplify integration in machines that coordinate spindle motion with other axis commands.
