KDF 1.2-100-300-W1-220

The KDF 1.2-100-300-W1-220 is a high-performance variable frequency drive manufactured by Bosch Rexroth Indramat as part of the KDF Variable Frequency Drives series. This 2nd version drive features a Rated Current of 100 A and a DC bus Rated Voltage of 300 VDC. Designed for advanced automation control cabinets, its primary function is to deliver precise speed and torque regulation for servo and motor applications, ensuring reliable performance in demanding industrial environments.

Equipped with a 300 VDC DC bus operating voltage and a 200 VAC control and fan supply, the KDF1.2-100-300-W1-220 offers robust power management. Its blower cooled design maintains optimal thermal conditions, while the drive's microprocessor-based digital velocity loop and analog velocity command enable ultra-responsive acceleration and deceleration profiles. Unique to this model are its unlimited four-speed operation capabilities, supporting speeds up to 8,000 RPM and down to zero RPM (dependent on load variation), plus 16 matching command bits that allow control of motors up to 25 horsepower.

The drive's control principle delivers industry-leading stability and stiffness, making it ideal for applications demanding tight motion control. It integrates seamlessly with Indramat Bosch Rexroth AC servo controllers using a single shared power supply, facilitating the creation of a complete brushless automation system at reduced cost. The robust blower cooling and standardized command interface enhance operational efficiency and longevity, while the specified repair procedures and replacement parts maintain system integrity. Backed by a one-year warranty, the KDF1.2-100-300-W1-220 drive provides exceptional reliability and precision in industrial automation deployments.
