Product Description:

For usage in robotics, CNC machines, and automation applications, Bosch Rexroth Indramat has developed the KDA 2.1-100-3-DP0-U1 AC main spindle drive. The drive uses the forced cooling system. The KDA drive is ideal for controlling AC motors. Its design prioritizes dependable performance in a wide range of operational environments.

The rated current of the drive is 100 A, and it was designed specifically for use in high-power applications. The drive is able to give precise adjustments to the motor speed with the assistance of the speed command value, 16-bit parallel. A heatsink blower that runs on 115 VAC AC power powers this KDA 2.1-100-3-DP0-U1 AC main spindle drive, which in turn functions on a DC bus voltage of 300 V.As per the specifications laid out by DIN 40 040, the drive can withstand temperatures between 5 and 45 degrees Celsius, with a maximum relative humidity of 70 percent.

The < is versatile for a number of setups due to its features, such as an auxiliary encoder input that provides feedback to the spindle or a second motor. The value of the temperature of the drive decreases to around 80 percent at 55 degrees Celsius when the temperature is higher than 45 degrees Celsius. A thermostat is responsible for this function. In addition, the motor functions exceptionally well in a wide range of temperatures and humidity levels. Because the spindle drive is humidity class F certified that the drive will continue to function properly in damp environments. Reliability and performance over the long term are guaranteed by the drive's heat management. When it comes to AC main spindle drives, Wake Industrial offers a replacement warranty that lasts for one year.
