Product Description:

With its high power and durability, the Bosch Rexroth Indramat KDA 2.1-100-3-DYD-W1 spindle drive has been developed to support increasingly complex automation and manufacturing applications.

The gadget is intended to function reliably and efficiently under high spindle loads, and it has an ongoing current rating of 100 A. It performs effectively in multi-axis settings where synchronized control is necessary for complex machinery operations since it can support three distinct axes. The drive has a DC 24 V control supply but needs a mains power supply module like TVM or KDV, and is compatible with modular drive systems of Bosch Rexroth. The 300 V DC electrical bus allows for a consistent and reliable power source. Inside cooling is controlled by built-in fans, and a blower that runs on 220 V AC is provided for prolonged usage. In terms of feedback, the KDA 2.1-100-3-DYD-W1 may have both resolver-based and digital servo feedback, which keeps the spindle speed and position accurately monitored. Flexible communication and control are available with SERCOS and analog 10 V interfaces, and a digital 16-bit parallel interface accepts speed command input, providing high-resolution performance.

The unit has a physical height of about 483 millimeters and 482.6 millimeters, making it a true industrial powerhouse. It is designed for a maximum depth of 380 millimeters, and depending on the configuration, it weighs between 11 and 15 kilograms, providing robust yet flexible construction. It is intended to be cabinet-mountable or panel-mountable and has a protection level of IP20, which needs to be installed in a guarded enclosure. With several demands for precision, dependability, and durability, the drive is intended to operate in temperatures ranging from 0 to 45 degrees Celsius.
