Product Description:
The KDA 3.2-050-3-A00-W1-220 spindle drive is produced by Bosch Rexroth Indramat and belongs to the KDA Spindle Drives series. It is intended for CNC machining centers, where it converts DC-link power into controlled three-phase output for spindle operation. This supports fast acceleration and deceleration while maintaining stable speed control during cutting cycles. In machine tools, the drive is suited to spindle axes used for drilling, milling, and similar high-duty applications. Internal monitoring and active airflow help the power section remain within normal operating temperature during continuous use.
The drive is supplied from a DC bus rated at 300 VDC and can deliver a continuous output current of 50 A, which suits medium-power spindle applications. That current capacity supports sustained spindle demand under the stated operating conditions. The blower uses an auxiliary supply of 220 V, 50–60 Hz, so the cooling circuit does not require a separate low-voltage fan source. Cooling is provided by forced cooling through a mounted heat sink blower that moves air across the fins and removes heat from the power semiconductors. The permitted ambient temperature range is 5 to 45 °C, and the unit is series 3 and version 2.
The speed command input is analog, which allows direct connection to legacy numerical controls without protocol conversion. The unit has no additional interface option, and it has no second encoder input, so feedback must come from the primary spindle sensor through the main connector. This arrangement limits the drive to its standard control and feedback path without expansion hardware. Installation altitude is limited to 1000 m above sea level to maintain full performance under the stated operating conditions. The connection layout is therefore suited to straightforward spindle systems that use the standard command and feedback channels provided by the drive.
