Product Description:

The KDA 3.1-050-3-L0I-W1 is a high-performance industrial controller unit designed to improve the operation efficiency of the 2AD and 1MB frameless spindle motors by ensuring that its speed, position, and general operations meet international standards. This controller is a slender compact unit widely known for its high stiffness, positioning feature and the ability to support connected motors over a broad speed range. The operation of this product is generally determined by configuration parameters, which are integrated into the programming module delivered with the unit. Some of the parameters required by this product have already been determined in the factory; however, the parameters can be easily changed by customers to adapt the unit to current operation requirements. The back panel of this product features a heatsink which works together with an external air blower for reliable temperature regulation.

The KDA 3.1-050-3-L0I-W1 features several connection interfaces, these includes the Bus for control voltage, motor NTC thermistor connection, and a terminal block for the motor and the DC bus. The easy handling of this product is guaranteed by its compact control panel, which features a display, LEDs, and a keypad. The operation of this product requires an ambient temperature range that is between 5 to about 45 degrees. Installation altitude for the proper operation of this unit should not be more than 1000 meters above sea level.

The KDA 3.1-050-3-L0I-W1 frequency converter operates with an external fan that serves as a heatsink blower. The air blower is independent of the drive itself and can be replaced independently. Operating this unit in a dirty environment should be avoided, as the accumulation of dust on the heatsink of the converter can reduce the effectiveness of heat dissipation. An air filter should be used when dirty external air is unavoidable.
