Product Description:
Bosch Rexroth built the KDA 3.2-050-3-APD-U1 Spindle Drive that belongs to its KDA Spindle Drive series. The company designed this drive for industrial automation systems. The drive accepts an analog ±10V speed command for precise control in spindle applications. It supports a continuous rated current of 50 A when its DC bus voltage is 300V.
The KDA 3.2-050-3-APD-U1 spindle drive has a forced air cooling system using a heat sink blower powered by a 115VAC supply. The encoder feedback offers precise positioning with resolution up to 1/360,000 of a revolution. The speed range is extensive, starting from 0.0005 rpm up to the maximum spindle speed. The drive features an auxiliary input designed for high-precision feedback and supports devices such as resolvers, synchronous encoders and tachometers. The drive dimensions are approximately 445mm x 110mm x 322mm, and it weighs about 16.6kg with the blower attached. The operational ambient temperature ranges from +5°C to +45°C with permissible short-term operation up to +55°C. The KDA 3.2-050-3-APD-U1 spindle drive can be stored safely between –30°C to +85°C and operates reliably in up to 95% non-condensing relative humidity. The drive can operate at elevations up to 1000 meters above sea level without reducing its performance.
The KDA 3.2-050-3-APD-U1 spindle drive offers vibration resistance compliant with industrial standards around 3g. The unit features built-in diagnostics via a front display and keypad, with integrated fault detection and watchdog circuits for operational safety. It carries an IP10 protection rating when installed in a control cabinet. The drive is designed for asynchronous and frameless spindle motors with continuous power ratings from 3kW to 22kW. It also allows configuration through an onboard programming module and supports modular replacement with drive-specific AS programming.
