Product Description:
The KDA 2.1-100-3-AQI-U1 is a drive controller developed by Rexroth Indramat for high-performance automation systems. It is a space-saving spindle drive with a unified heat-sink design for dense control cabinet layouts. This makes it adaptable to various system layouts including those with space constraints where multiple drives must be installed side by side. This compact thermal architecture allows for efficient heat dissipation without requiring excessive ventilation spacing, supporting tighter and more modular cabinet configurations. This drive is engineered to support an extensive speed range while maintaining continuous power output. This enables consistent performance across both low and high spindle speeds, ensuring improved throughput in dynamic motion control tasks.
The KDA 2.1-100-3-AQI-U1 includes an auxiliary encoder input designed to accept 1 V peak-to-peak sinusoidal signals. This allows it to receive high-resolution feedback from an additional encoder source. This input enhances positioning accuracy by enabling the drive to monitor motor shaft movement with greater precision. The drive also features an incremental encoder interface that enables it to receive position and speed feedback through a series of pulses generated by the motor's encoder. This interface allows the drive to track the motor's rotational movement in real time, supporting precise speed regulation and accurate positioning.
The KDA 2.1-100-3-AQI-U1 uses a 115 VAC supply source to power its heatsink blower, providing dedicated cooling for internal components. By drawing from a standard low-voltage AC line, the blower can operate independently of the main drive circuitry, ensuring continuous airflow even during low-power or standby conditions. This helps to maintain stable thermal conditions within dense control cabinets. The drive supports a current of 100 A, enabling it to effectively handle high-throughput systems that require robust power without risking thermal overload.
