Product Description:

Bosch Rexroth Indramat makes the KDA 2.1-100-3-DP0-W1 AC Main Spindle Drive. It is designed for CNC (Computer Numerical Control) machines, which use high-speed rotation to precisely cut, drill, and grind materials such as metals, polymers, and composites. The drive is constructed with heavy-duty components to ensure optimal operation in a variety of industrial environments.

The KDA 2.1-100-3-DP0-W1 AC main spindle drive can handle up to 300V of power. The digital 16-bit parallel speed setpoint on the drive makes it easy to control the speed. Within a temperature range of +5°C to +45°C, the drive is able to function properly. The drive can be used in places with different amounts of humidity and does not need much maintenance. To bring the temperature down, a heat sink fan and an AC power source operating at 220V and 50-60 Hz are utilized. During the driest month, the humidity can reach as high as 70 percent, and the drive is in compliance with DIN 40 040 regulations due to its Humidification Class F. The drive can also take a 1V sine wave as an input for extra control. The drive does not need any extra interfaces besides the ones it already has for input and output. The drive operates with 100A of current.

The KDA 2.1-100-3-DP0-W1 drives's cooling system uses a heat sink fan to force air flow, which keeps the temperature stable. At a temperature of 55 degrees Celsius, a thermal derating device reduces the output of the drive by 80%. The drive is reliable for continuous use because of its small size and effective cooling. The KDA spindle drive is a great choice for demanding tasks that need exact control and good power management because of its features.
