Product Description:
The KDA 3.2-050-3-AYS-W1 spindle drive is manufactured by Bosch Rexroth Indramat for the KDA Spindle Drives series, and it is hardware release 3.2. It serves as the regulated link between a CNC controller and a high-speed spindle, converting command signals into controlled motor torque for drilling, milling, and grinding machines. Integrated heat-sink ventilation and field-oriented control allow the unit to operate as a compact power stage in automated machining cells. The design is intended for cabinet installation where precise speed regulation and dependable thermal management are required.
During service, the drive can deliver up to 50 A of continuous motor current. Its power section is supplied from a common bus of 300 VDC, so the installation must provide suitable isolation and surge protection. The heat-sink blower operates from an auxiliary supply of 220 V at 50/60 Hz, which keeps airflow available even when the main DC link is de-energized. Heat is removed by a mounted heat-sink blower with forced cooling, helping maintain device temperature during sustained spindle loads. Full output is available within an ambient range of 5 to 45 °C. For setup and diagnostics, the control board includes an RS-232-C serial interface so parameters and fault data can be accessed without removing the unit from the cabinet.
The drive sustains rated output up to 1000 m above sea level without derating at typical factory elevations. Precision applications benefit from a second encoder input and synchronous input, which support spindle orientation and dual-loop control. Speed reference signals are accepted through an analog ±10 V input, making integration straightforward with legacy motion controllers that use this command format. This arrangement lets the controller receive both velocity commands and additional feedback paths during spindle operation.
