Product Description:
The KDA 2.1-100-3-LQ0-U1 part number belongs to the KDA series and is identified as a spindle drive. It delivers a high performance industrial control of the spindle motors. The drive has an input rated current of 100 amps and this implies high drive capacity in high speed spindles operations.
The KDA 2.1-100-3-LQ0-U1 spindle drive has a three phase main power connection that provides balanced and stable power delivery. It maintains its ambient temperature through forced cooling using a heat sink blower unit. The drive uses 300 VDC of power to operate the DC bus and it uses SERCOS interface for effective speed control and communication. The drive ensures industrial cycle stability in running the equipment. The blower is an AC load with a 115 Volts rating and runs on frequencies of 50 to 60 Hertz. The KDA 2.1-100-3-LQ0-U1 spindle drive has an optional auxiliary encoder input to receive 1V peak-to-peak encoder signals. It drive makes wiring connection through its 9-pin connection clamps. The drive is designed to operate under no more than 95 percent relative humidity without condensation to avoid damage due to moisture. The protection rating of this drive module is IP20 and must be installed in a secured cabinet.
The KDA 2.1-100-3-LQ0-U1 spindle drive is mostly used in high-speed machining and automation systems. It is a highly protected category that will not be hazardous to use under regulated circumstances. The system operates at a definite altitude of 1000 m. above sea level without derating. It has an ambient operating temperature of 08C to +45C which makes it versatile in most industrial settings. The specified range of temperature helps the drive to perform well in varying temperatures.
