Product Description:
KDA 3.1-050-3-LQ0-U1 is a spindle drive designed for control for 2AD and 1MB motors from Bosch Rexroth. KAD drives can deliver rated output ranging from 3 to 22 kilowatts. Salient drive features include a wide speed range, positioning, and high stiffness. These features make KDA drives an optimal choice for applications involving use of numerically-controlled machine tools. A microcomputer on the drive performs all diagnostics, monitoring, and control functions. An integrated display and input unit allows drive parameterization. Multiple interface options are available, including SERCOS, ±10 Volts command interface, and position and speed command interfaces. Drives with a SERCOS interface allow diagnostics and parameter handling from an NC interface. KDA 3.1-050-3-LQ0-U1 is a drive with 50 Amps rated current output. Its DC bus voltage is 300 Volts DC.
The speed command interface is SERCOS. KDA drives can support two auxiliary interfaces. There is one auxiliary interface on this drive, and it supports 1V sinusoidal encoder input. A heat sink blower provides surface cooling. The supply voltage for this blower is 115 Volts at 50 to 60 Hertz. Continuous current output of the drive is 35 Amps. The drive unit weighs 16.6 kilograms. Weight of the mechanical mounting kit is approximately 1.7 kilograms and the blower weighs 4.2 kilograms. The permissible ambient temperature for KDA drive operation is 5 to 45 degrees Celsius. Operation with reduced nominal data is permitted at temperatures reaching 55 degrees. Unused KDA drives can be stored in environments where the temperature is maintained between -30 and 85 degrees Celsius. The permitted maximum installation altitude that does no cause a reduction in nominal data is 1000 meters. Protection class of the KDA 3.1-050-3-LQ0-U1 drive is IP10.
