R911225691
The R911225691 (KDF1.2-050-300-W1-220), produced by Bosch Rexroth Indramat, is a high-functioning variable frequency drive designed to effectively manage motors of up to 25 HP (kW). Its unique features such as a 16-bit parallel digital command input facilitate seamless operation with any control system. The R911225691 (KDF1.2-050-300-W1-220) utilizes a digital velocity loop for precision speed control and inhibits drift for maintaining accuracy over time. With a diverse speed range of 0 - 8000 rpm, this drive also displays high stability and stiffness even at zero speed, thereby withstanding changes and delivering optimal system torque.
This variable frequency drive is built to be compatible with Indramat's modular AC servo controllers, providing an efficient, cost-effective brushless design. It includes a power transformer to adapt to the required 220 VAC input voltage. Customization is enabled through the parametrization feature, storing these parameters in an EEPROM located on the AS2 personality module. To assure peak data transmission from the incremental encoder to the drive, a short shielded cable is essential. The R911225691 (KDF1.2-050-300-W1-220) is designed to be maintenance-free thus eliminating the requirement for regular upkeep.
