KDA 2.1-050-3-D0D-U1

Product Description:

The KDA 2.1-050-3-D0D-U1 drive comes in through Bosch Rexroth Indramat’s KDA Spindle Drives series. This model supports two-axis spindle operations and its rated current hits 50A, handling setups that draw more power than what lighter units can do. Power comes into the drive somewhere between 3 x 380–480V AC, and it’ll take swings up to ±10% in supply, so it still works steady when factory feeds aren’t perfect. Input frequency is marked at 50/60 Hz, keeping things moving whether wired on North American or European lines. Size and build make it at home with tough automation layouts that don’t give extra room for wide frames.

Air cooling takes care of heat on this drive, moving air inside with its own fan so nothing overheats during nonstop use. The design focuses on keeping up with industrial workloads while using IP20 protection, stopping fingers or foreign bits from getting into sensitive places, though it probably needs less dirty surroundings. Integrating with machines sometimes means feeding back the shaft’s position or speed for adjustments as things change, so feedback comes through a resolver or encoder, letting choice match the connected motor. Connections for control run analog or digital so there’s plenty of ways to hook it with other gear on the same production floor or line.

A drive like the KDA 2.1-050-3-D0D-U1 weighs in at about 15 kg, making installation something a few handles or brackets can solve without extra equipment. The storage range dips to -25°C, so cold or odd storage situations won’t mess it up between swaps or repairs. Operating stays solid until +45°C without reliability sliding downhill. These drives sit in the core of big CNC spindles or automated machining setups needing sharp repeatability and raw dual-axis power.
