KDA 3.1-100-3-AYD-U1

Product Description:

The KDA 3.1-100-3-AYD-U1 spindle drive from Bosch Rexroth Indramat is part of the well-established KDA Spindle Drives family. Built with a panel mount format, the unit fits easily into standard drive cabinets. This drive provides steady current at 100 A, allowing MAC motors to run under consistent load without ripple. A 3-phase power input rated for 380 to 480 V AC makes it a fit for most industrial panels without needing special adaptation. It also runs on 50/60 Hz frequency, adding to its global compatibility.

Cooling is handled through a simple air-cooled design, which keeps components inside the unit stable without needing liquid setups or extra ventilation. At a weight of about 35 kg, the unit is compact enough for mid-range control racks, and the internal structure supports proper heat dispersion during extended cycles. It includes a digital servo amplifier setup and a proprietary communication interface built specifically for Indramat systems. This matches well with MAC servo motors, which are directly supported without compatibility adjustments.

The protection rating on the unit sits at IP10, providing some defense against accidental contact in clean control environments. Operation is stable between 0°C and 45°C ambient temperature, keeping it functional across most factory setups without needing climate control. Axis configuration is marked as 3-axis, so multi-load platforms can run under shared control with lower wiring overhead. Internal response is fast and direct due to the digital feedback loop inside the amplifier section. Installation is mechanical and electrical both straightforward, provided standard rack dimensions are followed. This model focuses on keeping control systems lean, efficient, and modular for fast replacements or layout changes. Output stays precise, even in systems demanding high spindle speeds and frequent motion shifts.
