KDA 3.3-050-3-DYS-W1

The KDA 3.3-050-3-DYS-W1 drive from Bosch Rexroth Indramat belongs to the KDA Spindle Drives series. It delivers precision control and high dynamic stiffness for main spindle applications. Designed as a compact 3-phase module, it supports continuous power outputs with accurate positioning across a wide speed range. Built to integrate into modern CNC and milling centers, the drive ensures consistent performance under heavy loads.

Equipped with a DC Bus Voltage of 300 V, the unit handles a Rated Current up to 50 A for sustained spindle acceleration. Speed feedback is managed via a Speed Command Value with Digital 16-Bit Parallel resolution, supported by an Aux. Encoder Input supplying both auxiliary and synchronous signals. Thermal stability is ensured by Forced Cooled by Heatsink Blower technology powered via an AC Supply Source for Heatsink Blower at 220 VAC. Connectivity options include a dual-mode Aux. Interface with Serial Interface RS 232 C, simplifying parameterization and diagnostics. The drive’s Design code 3 and Product family KDA establish clear service identification and spare parts compatibility.

Engineered for robust industrial integration, the KDA 3.3-050-3-DYS-W1 easily interfaces with CNC controllers and PLCs via its flexible I/O. Its forced-cooling blower and durable construction deliver high reliability in demanding environments. Ideal for precision milling, grinding spindles, and drilling applications, it enhances machine uptime and throughput.
