Product Description:
The Rexroth Indramat KDA 3.2-050-3-DP0-U1 is a spindle drive that is structured to work with digital 16-bit parallel speed setpoints. The drive includes provisions for an additional encoder input that supports spindle feedback or second motor feedback functionality.
The KDA 3.2-050-3-DP0-U1 spindle drive incorporates IP 10 protection according to DIN 40 050 that ensures resistance against objects larger than 50 mm. The thermal design is based on an external heatsink with forced cooling through a blower that uses bottom-to-top airflow. The blower mounts directly on the frame that allows drive replacement without disassembly. Speed command interfaces are provided through ±10 V analog, SERCOS, and digital parallel inputs that allow flexible integration. Encoder outputs are incremental and programmable in resolution. A serial interface is available that allows parameter storage and retrieval via a PC. Feedback resolution reaches 1 part in 2,000,000 revolutions on the rotor and up to 1 part in 360,000 revolutions on the C-axis. The AC main spindle drive has a continuous output power range between 3 kW and 22 kW. The drive operates with a continuous current rating of 50 A at 300 V.
The drive features an AC supply voltage for the heatsink fan rated at 50–60 Hz operation. The encoder interface provides flexibility for incremental outputs with programmable resolutions that align with diverse machine requirements. In order to provide cooling, a heat sink fan is utilized, which ensures that there is a constant flow of air throughout the system. The drive is constructed with support for digital parallel communication, which guarantees precise control of both the speed and the position respectively. The AC main spindle drives come with a replacement guarantee from Wake Industrial that lasts for one year.
