Product Description:
The KDA 3.1-100-3-L0S-U1 is an internationally certified main spindle drive designed by Danfoss to provide industrial engineers who use the 1MB and 2AD motor series with a drive that guarantees optimum monitoring and control. The drive has been in circulation for more than 10 years and is widely popular for its high efficiency and user-friendly operation. The metallic enclosure for this converter is designed to protect its internal components from large foreign solids, and it also makes it possible for the unit to be vertically installed inside a control cabinet. The operation of this product is determined by the instructions stored inside the AS 3 programming module. This module is delivered with the drives and can be transferred between different units for a faster configuration process. The configuration parameters stored on the programming module can be freely modified by the operator depending on configuration requirements.
The KDA 3.1-100-3-L0S-U1 main spindle drive has a Motor Negative Temperature Coefficient thermistor connection; the feedback from the motor thermistor is received through this connection and used to determine the temperature level in the product and prevent overheating. There is also a control panel present on this product; this panel features a single-line display and pressure keys. There are also two Light Emitting Diodes (LEDs) to signal “Ready” and “Fault status” on this product.
The KDA 3.1-100-3-L0S-U1 main spindle drive features a heatsink and air blower that work together to keep the temperature inside the enclosure of this product within a permissible level. The blower is not part of the delivery package of this drive; it is a separate component that should be ordered separately for use. The input voltage requirement for this product is 300 volts; it also operates with an input current of 100 amperes.
