Product Description:

The Bosch Rexroth KDA 3.2-100-3-DP0-U1 is a precision spindle drive suited for demanding motion control tasks. Its integrated digital control enables accurate, real-time regulation of spindle performance, ensuring smooth transitions. The drive's wide speed range allows it to perform both controlled operation for precise finishing and quick acceleration for high-speed machining. This drive has a rated voltage of 300 V that ensures the drive has enough power to effectively transfer energy to the connected motor. The drive can maintain smooth speed regulation and torque output under a variety of load conditions, ensuring consistent and energy-efficient operation.

The continuous current capacity of the KDA 3.2-100-3-DP0-U1 is 70 A, which allows it to operate with high stability for extended periods of time. This level of current keeps the spindle from overheating or fluctuating in power during extended duty cycles. In high-load conditions, the drive can achieve a maximum current of 100 A, providing the added capacity required for demanding duty cycles. This ensures that the drive can respond quickly to fluctuations in load and speed conditions without excess wear. The 16-bit parallel speed command value used by this drive allows for quick and accurate communication between the drive and the control system.

For flexible integration, the KDA 3.2-100-3-DP0-U1 comes with an additional encoder input that can be utilized for spindle or second motor feedback. These external feedback options make it possible for the drive to deliver tighter synchronization and increased accuracy in motion control. The drive is optimized for thermal stability with an attached blower that actively cools the drive while it is in use. This blower efficiently eliminates excess heat, enabling the drive to function within safe temperature limits under load.
