KDA 2.1-150-3-AY0-W1

The Bosch Rexroth Indramat KDA 2.1-150-3-AY0-W1 drive from the KDA Spindle Drives series delivers precision control with a Rated Current 150A output and a DC bus Voltage 300 V. This spindle drive accepts a three-phase 380-480 V AC supply type and employs an analog control scheme with a Speed Command value Analog +/- 10V for accurate speed regulation. Its design supports two-axis control and integrates seamlessly into industrial automation systems by Bosch Rexroth. Compact yet robust, it is tailored for demanding spindle applications where uptime and accuracy are paramount.

Featuring advanced thermal management, this unit includes a Cooling type forced cooling by heatsink blower and a dedicated Heatsink Available to dissipate heat efficiently under continuous load. The Supply source for heatsink 220V (AC) operates within a Frequency range for heatsink 50 to 60 Hz, ensuring consistent cooling performance across global installations. An Auxiliary Encoder input with auxiliary and synchronous inputs (due to AS 35 and speed command value = A) enables precise feedback integration without additional interface modules. Internal air cooling and an IP20 protection rating safeguard internal electronics against contaminants while maintaining a streamlined cabinet footprint.

Environmental resilience is built in with a Permissible ambient temperature +5 to +45 °C for nominal operation and a Permissible maximum ambient temperature 55 °C at reduced nominal data, ensuring reliable performance in varied factory climates. With the ability to function at altitudes up to 1000 m and designed per industrial automation standards, the KDA 2.1-150-3-AY0-W1 maintains stability under challenging conditions. Maintenance is simplified by its modular heatsink blower assembly and standardized Bosch Rexroth interfaces, reducing downtime and lifecycle costs.
