Product Description

The KDF1.2-100-300-W1-115 is part of the KDF series of variable frequency drives from Rexroth Indramat Company. It features a weight of 45 pounds, maximum power during heat dissipation of 150 Watts, and a power rating of 30 KVA. Its electrical parameters include a 3 x220 VAC rated input voltage, 300 VDC output voltage, and 100 Amps rated output current and 300 Amps peak output current. It utilizes a blower cooling method to maintain ambient conditions inside the control cabinet. The ambient operating conditions are a temperature range of 5 to 45 degrees, a maximum installation height of 1000 meters above sea level, and a permissible humidity of 70%.

The KDF1.2-100-300-W1-115 has a protection degree of IP 10 and should be installed in a cabinet that meets IP 10 requirements. The unit should have a heatsink to conduct heat away from the cabinet and an air duct to collect condensation water. It has a speed range of 0 to 8000 RPM making it ideal for small to high speed demanding tasks on the factory floor. The KDF1.2-100-300-W1-115 provides high performance when operating motors of up to 25 horsepower. This drive allows positioning and unrestricted four-quadrant operation.

It can comprise a 16 bit parallel digital command input or differential analog command input to allow operation by any control system. The speed control of the KDF1.2-100-300-W1-115 is highly accurate owing to the built-in microprocessor-based digital velocity loop that mitigates the formation of drift. The principle used to control the motor system provides the highest stiffness and stability for standard induction motors. Since it can be combined with a modular AC servo controller, it allows a complete brushless machine to be constructed at a reduced price. This product is available from Wake Industrial with a one-year warranty period.
