KDA 2.1-050-3-D0I-U1

Product Description:

The KDA 2.1-050-3-D0I-U1 shows up as a drive controller from Bosch Rexroth Indramat that’s part of their KDA Spindle Drives family. A big point here is the rated current of 50 A, which covers machines with a lot going on—three axes under its control for setups that aren’t running simple, single moves. Instead of random voltage swings, it settles in nicely on 3 x 380-480 V AC mains supply, so it doesn’t fall out of line with facility power. The controller itself steps into the cabinet and parks there out of the way, total weight hitting about 19 kg, heavy enough for stability but not so much it’s tough to move.

This model grabs attention with an IP20 protection class, which blocks solid objects up to a limit. Not totally waterproof, but decent for typical factory gear that’s more focused on function than getting sprayed down. On the control side, 24 V DC runs just for the control voltage, which helps keep signals clean when powering up or moving through cycles. Digital comms show up here too, with SERCOS interface compatibility built right in. Plug in the right servo motors and it talks directly—nice if spindle or axis feedback matters for the application.Indramat AC Servo Motors match with this drive, staying in the same Bosch Rexroth family, so everything lines up.

For cooling, internal air circulates to keep power electronics and connections from running too hot. Around 360 W of power loss (dissipation, not output), so the internal blower gets regular use. The design and layout mean installation keeps fuss to a minimum—cable runs stay tidy and panel layout fits into common industrial electrical cabinets. Usual working temperatures stretch from 0°C to +45°C, so it doesn’t flinch at high or low warehouse temps.
