Product Description:

Bosch automation portfolio includes advanced spindle control systems. The KDA 3.1-050-3-APS-U1 Drive supports diverse machining spindle requirements. It is designed to regulate speed and torque in industrial environments.

The KDA 3.1-050-3-APS-U1 drive works at a rated voltage of 115 VAC. The spindle drive consumes a nominal current of 50 A. It comes with an integrated heatsink blower cooling component. The cooling mechanism maintains reliable heat dissipation during high load operation. It includes encoder input channels labeled as auxiliary type. The encoder input is present for motor feedback operations. It uses an RS 232 C interface standard. The serial RS 232 C link allows remote adjustments of the parameters. It also provides diagnostics and status monitoring. The serial interface supports stable data transmission. The feedback is exclusively designed for motor feedback regulation. It maintains consistent spindle speed under changing loads The operating temperature range is from 0°C to +45°C. This operating temperature range supports integration into enclosure-based machines. It provides steady working in enclosed control cabinets. The spindle drive enclosure is suitable for both rack or panel mounting. The spindle drive supports accurate spindle control in CNC machinery. It delivers stable current up to 50 A. The cooling mechanism protects internal components during prolonged working. The design ensures safe functioning under standard industrial environments.

The KDA 3.1-050-3-APS-U1 spindle drive provides accurate and effective spindle control performance. Bosch spindle drive uses encoder feedback to maintain torque stability. It also incorporates a heatsink blower with serial RS 232 interface which increase the cooling performance of the heatsink. The motor feedback channel stabilizes both torque and speed performance. The casing of the spindle drive supports panel mounting without external cooling fans. It maintains performance under rated current draw.
