KDA 2.1-050-3-D0D-W1

Product Description:

The KDA 2.1-050-3-D0D-W1 drive comes from Bosch Rexroth Indramat, sitting in their KDA Spindle Drives collection for digital motion setups. This model pulls 50 Amps as its maximum current, which lines it up for use on automation lines that put a demand on spindle motors day after day. With a three-phase power supply plus internal blower (D) cooling, the design holds off overheating and lets extended runs happen without stopping. The weight sits around 18 kg, making it manageable for fittings or upgrades even when space gets tight in existing cabinets.

Electrical specs zero in on a nominal bus voltage of 300 V DC so it pairs well with modern inverters or existing DC buses. Flexibility matters for speed and torque control — this model supports various encoders or resolver feedback, which really helps for users switching out spindles or tweaking automation lines. Connections work by SERCOS protocol in setups where digital comms matter, but options can flex depending on individual configurations. It runs as a digital intelligent drive controller and controller version marks as 2.1, plus a regulator type 3 that signals a specialized internal control compared to basic units.

Weather and usage stress usually beat up drives, but this one's protection rating of IP10 gives some basic isolation (as always, mounting affects the setup too). The build focuses on staying reliable in moderate factory environments; it doesn’t mind running in spots between 0°C and 45°C. That standard (D0D) cooling helps manage dust and airflow inside cabinets. It’s a fit for medium to heavier spindle work in industrial buildings and lines that see start-and-stop work all week. When quick stops or ramp-ups are needed — like in handling, packaging, or mid-range machining lines — this drive’s feedback and controls help prevent drift or errors.
