KDA 3.2-050-3-AQD-W1

The KDA 3.2-050-3-AQD-W1, Bosch Rexroth Indramat, KDA Spindle Drives series delivers high-stiffness main spindle control optimized for precision machining. Engineered to support broad speed ranges and continuous high power, it offers tight position-loop performance for complex toolpaths. Robust design minimizes vibration, ensuring repeatable accuracy across load variations. Its compact form factor simplifies integration into milling, grinding, and drilling centers.

This drive operates on a DC Bus Voltage of 300 V and sustains a Rated Current of 50 A, enabling consistent torque delivery at elevated speeds. Thermal management relies on Cooling via a heatsink blower, powered by an AC Supply Source for Heatsink Blower of 220 VAC, which maintains optimal junction temperatures during extended cycles. Motion commands are accepted through an Aux. Interface featuring a Position Command Value Digital 16-Bit Parallel protocol, while the Speed Command Value input accommodates Analog +/- 10V signals for fine velocity regulation. Feedback loops are enhanced by an Aux. Encoder Input compatible with 1V sinusoidal encoders, elevating position resolution and dynamic response. Classified under Design code 2 and catalogued as Product code KDA, the module aligns with series 3 specification standards. Its forced-cooling architecture ensures stable operation even under peak load.

Seamless connectivity with Rexroth CNC controllers and I/O modules allows coordinated multi-axis synchronization, reducing cycle times and improving surface finish quality. The robust cooling system and encoder feedback resilience guarantee dependable performance in high-duty applications, lowering maintenance intervals. Overall, the KDA 3.2-050-3-AQD-W1 spindle drive enhances throughput, precision, and uptime in advanced manufacturing environments.
