Product Description:

The part number KDA 3.1-150-3-LYS-U1 is a Spindle Drive that controls the flow of electricity to the motor based on the given input signals. It is designed by Bosch Rexroth Indramat which develops superior solutions that can be utilized to solve industrial-grade problems.

The KDA 3.1-150-3-LYS-U1 drive consumes a consistent 90 A current as its initial startup requirement. This unit operates at a 24 V load voltage with a consumption of 1.6 A and features a ±15V measuring voltage with a current draw of 160 milli Amp. It weighs only 17.4 kg and with the mechanical mounting kit with a (M1-KD) added, that has a mass of merely 1.7 kg which makes it simple to mount and integrate out-of-the-box systems. The blower unit carries 4.2 kilograms and is efficient at cooling and it does not overheat. This drive unit is made to work in the ambient temperatures up to a highest threshold of 55 degrees Centigrade but nominal data can be diminished under the conditions. Its storage and transportation temperatures are between -30 and 85 degrees Centigrade which portrays its versatility in varying industrial automation domains.

The KDA 3.1-150-3-LYS-U1 spindle drive has an analog input that is perfectly suited to speed control where the command value is ±10V which gives it very smooth and accurate adjustments. There is also an auxiliary encoder input of the unit which allows synchronous operation to the AS35 standard. Its serial auxiliary interface uses RS-232C classification which enables easy communication with external devices and also increases adaptability to this unit. It is CE certified which aids in improving its trustworthiness in multiple high-grade industrial platforms.
