KDA 3.1-100-3-AY0-W1

Product Description:

The KDA 3.1-100-3-AY0-W1 spindle drive is part of the KDA Spindle Drives series from Bosch Rexroth Indramat. This analog model uses a traditional analog command interface, which helps it stay compatible with a wide range of existing industrial setups. Built to run with a control voltage of 24 VDC, it also includes support for motor field supply, adding flexibility for motor types with separate excitation. Weighing around 36 kg, the unit mounts directly onto panels, following a straightforward panel mount setup.

Rated for 100 A output current, this drive is capable of running multiple loads across its three-axis support. The electrical input can handle 3 x 220-230/400-460V AC supply, covering both low and high voltage systems. A key feature of this drive is the resolver feedback system, helping with position control in spindle operations where speed and angle tracking matters. It’s cooled using external air cooling, pulling ambient air to control internal heat without needing complex liquid systems.

The drive has an IP20 protection rating, meaning it’s intended for cabinet installation where extra shielding is already in place. Inside controlled environments, this rating is generally enough for dependable operation. With steady current output and support for analog control, this drive fits spindle-based applications like CNC centers or rotary axis tables. The hardware layout keeps the wiring and terminal access open enough for maintenance without taking much space. Cooling fans, if installed correctly, keep airflow steady, especially in multi-drive panels. This model remains a reliable choice where analog systems are still running and upgrades need to match the older infrastructure without forcing a full system change.
