Product Description:
The Bosch Rexroth Indramat’s built KDA 3.2-100-3-AY0-W1 Spindle Drive is designed to work effectively with controlled temperature conditions. This spindle drive accommodates an operating temperature range of +5 to +45 °C, providing uninterrupted and stable drive performance during machine usage. For transport and storage, this drive tolerates a temperature range of -30 to +85 °C, safeguarding the internal mechanisms in a non-operating state.
The KDA 3.2-100-3-AY0-W1 spindle drive features forced cooling by a heatsink blower that ensures maximum heat dissipation during heavy use. This drive’s heatsink blower draws power from an AC source of 220 V with 50-60 Hz frequency, which provides cool air and protects against heat overload. For control accuracy, this spindle drive accepts a speed command of analog ±10 V. This type of input makes it possible to have direct and precise regulation of spindle speeds. The addition of auxiliary and synchronous encoder inputs to this spindle drive provides precise feedback, improving spindle synchronization and monitoring. This spindle drive also provides a rated current of 100 A in support of power-hungry spindle demands. The KDA 3.2-100-3-AY0-W1 drive operates at a DC bus voltage of 300 V, which is a standard for industrial power systems for effective energy transmission.
The motor connection of this KDA 3.2-100-3-AY0-W1 spindle drive needs a tightening torque of 5 Nm, ensuring safe connections and stable transmission of electrical power. This drive’s configuration facilitates installation at a maximum height of 1,000 meters above sea level, which makes it widely applicable to different site locations. The environmental protection of this drive is ensured by humidity classification F according to DIN 40 040 to operate without performance degradation. The system connectivity of this drive is facilitated via NC connecting clamps marked X2 with a 37-pin interface for secure and organized signal integration.
