Product Description:
The KDA 2.1-100-3-AQD-W1 is a servo spindle drive designed for synchronized multi-axis systems. Its integrated SERCOS interface facilitates timing precision with the controller, delivering accurate and coordinated motor control across multiple axes. This drive regulates the rotation of spindle motors by controlling speed, torque, and direction based on digital input signals. This allows the motor to respond to real-time application requirements, adjusting performance for optimal productivity and efficiency. This drive accepts speed command input in the form of an analog ±10V signal, allowing for continuous and proportional control of spindle motor speed. This allows for easy integration with controllers and PLCs that output analog signals, supporting flexible system configurations.
The KDA 2.1-100-3-AQD-W1 is engineered with high stiffness, indicating its ability to maintain precise control over motor position and speed with minimal deviation under load. In servo systems, stiffness directly affects how accurately the drive responds to external disturbances or sudden changes in torque demand. High stiffness ensures that the spindle maintains its commanded trajectory without overshooting or lag, which is critical in multi-axis systems where synchronization between axes must be exact. This leads to improved machining precision, tighter process tolerances and higher overall system responsiveness.
The KDA 2.1-100-3-AQD-W1 operates with a DC bus voltage of 300 V, which serves as the internal power supply level used to drive the connected spindle motor. This voltage is derived from rectified AC input and provides the necessary energy for efficient and responsive motor operation. The drive has a temperature tolerance of 0 to 45°C during operation, making it suitable for most industrial environments. This range allows the drive to perform reliably without the need for special climate control, provided adequate ventilation is maintained.
