Product Description:
The KDA 3.1-150-3-A0I-U1 is an AC main spindle drive designed by Indramat to meet precise positioning and trajectories in a variety of industrial automation applications. Powerful and reliable performance is assured by the spindle drive, which is engineered for spindle positioning, C-axis control, and speed control. It incorporates real-time position, speed, and torque feedback.
The KDA 3.1-150-3-A0I-U1 AC main spindle drive has a current rating of 150A. The drive has a limited speed setpoint input of +/-10V for speed adjustment. The drive must include an incremental encoder to provide feedback data. A heat sink is provided by the forced cooling system fans that are utilized by the AC main spindle motor. Because it has a voltage rating of 300V, the spindle drive is an excellent choice for applications that require a lot of power. The AC supply voltage for the fan is 115V, and the drive’s fan must operate at 50-60Hz. In terms of temperature, the AC main spindle drive operates in a temperature range of +5° C to +45° C, indicating full performance, while +55° C is the highest allowable temperature, indicating performance degradation. The KDA spindle drive can be utilized at altitudes of up to 1000 meters. The cooling type of the drive enables thermal management systems, allowing operations to be carried out under heavy loads.
The KDA 3.1-150-3-A0I-U1 AC main spindle drive features digital microcomputer control with built-in speed and position control. Position, speed, and torque are sent in real time via SERCOS (Serial Real-Time Communication System). The continuous operation with feedback is acceptable under simulated environmental constraint conditions. The drive is suitable for challenging applications that require precise accuracy and strong control over operations.
