KDA 3.2-050-3-AQS-U1

The Bosch Rexroth Indramat KDA 3.2-050-3-AQS-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers robust spindle control with a Rated Current of 50 A and a DC Bus Voltage of 300 V for demanding machining applications. It supports an AC Supply Source for Heatsink Blower of 115 VAC to maintain optimal thermal conditions under heavy loads. Precision speed regulation is achieved via an Analog +/- 10V Speed Command Value, while communication and diagnostics are facilitated through a built-in Serial Interface RS 232 C. The drive’s forced cooled by heatsink blower configuration ensures consistent heat dissipation, reducing the risk of thermal derating.

Engineered as part of the KDA family, this main spindle drive features an integrated Aux. Encoder Input for 1V Sinusoidal Enc. that delivers fine position feedback and smooth motion control. The modular Design 2 housing and Product KDA architecture simplify installation and serviceability in multi-axis CNC systems. A dedicated Series 3 control module consolidates power electronics and logic in a compact form factor, saving valuable cabinet space. Sealed connectors and rugged components provide reliable operation in high-vibration environments.

Optimized for high-stiffness positioning and extensive speed range, the KDA 3.2-050-3-AQS-U1 drives spindles with continuous power and rapid dynamic response. Its combination of 50 A rated current, advanced encoder interfacing, and efficient cooling makes it an ideal solution for precision milling, drilling, and grinding centers. Users benefit from reduced maintenance cycles and enhanced process stability, ensuring maximum uptime and throughput in modern manufacturing workflows.
