Product Description:

The KDA 2.1-150-3-L0D-W1 is an AC main spindle drive made by Indramat for tasks that need precise control of speed and accuracy. The spindle drive works perfectly with CNC machines, industrial automation systems, and other tools that need to be controlled precisely and quickly.

The KDA 2.1-150-3-L0D-W1 main spindle drive can handle a 300V AC source and a 150A current rating. For accurate operation, it has a 16-bit parallel position setpoint and a SERCOS interface for controlling the speed. The cooling fan is an important part that moves air around the unit to get rid of heat and keep it running at the right temperature. The fan works at a frequency of 50–60 Hz and is powered by a 220V AC source. Its AC voltage source makes it more reliable to use in a variety of settings. In line with DIN 40 040, the drive also has a humidity grade of F, which means it can work reliably in a range of moisture levels. The main spindle drive can be used in many fields, such as CNC machines, precision grinding, woodworking machinery, and packaging machines, because it is reliable, uses little energy, and enables the user to regulate the speed.

The main spindle drive is designed to work best in temperatures between +5°C and +45°C, but it can function safely up to +55°C. The unit can withstand high temperatures and can be installed up to 1,000 meters above sea level, so it can be used in a variety of settings. It is made to last longer and use less energy. In tough settings, the KDA 2.1-150-3-L0D-W1 main spindle drive is the best choice because it can work in different temperature ranges and can be cooled by force.
