Product Description:
Component number KDA 3.2-100-3-A0D-W1 is engineered by Bosch Rexroth Indramat which signifies the KDA Spindle Drives product lineup. This equipment supports tacho and resolver feedback to supply both incremental and absolute position signals for flexible position and speed control. Field supply voltage values DC 310V establishes the drive DC link which enables stable inverter operation and consistent torque output across the speed range. Compatible motors include MDD, MKD, 2AD, and 1MB series and select variants that match electrical interfaces and feedback types.
The drive’s rated current of 100A sets the limit for continuous operation and guides the choice of conductors, protective elements and thermal safeguards. IP10 safety standard offers only basic defense against objects falling vertically. This particularly means the unit must be housed in an enclosure to prevent accidental contact with energized parts. The mass of 28 kg requires safe lifting during installation and stable panel support once in place. Its overall size of 395 x 205 x 325 mm facilitates the layout space and clearance planning needed inside the electrical cabinet. The supply rating of 3 x AC 220/230 Vfor this variant provides the three-phase input that energizes the inverter section.
The KDA 3.2-100-3-A0D-W1 spindle unit is designed with a continuous current rating of 100A which directly supports the device’s sustained torque output. A peak current capacity with 3 times greater than the rated value allows it to handle temporary overloads during acceleration. This actually shapes how protection thresholds are configured. Cooling is achieved through a blower system where an external fan drives airflow across the heatsinks to keep temperature under control, enabling long duty cycles but requiring a clean intake path. This panel-mounted gadget is secured within the control cabinet and keeps wiring organized and ensures reliable positioning for service or replacement.
