Product Description:
Bosch Indramat is known for reliable drive technologies used in motion control and automation systems. The KDA Spindle Drives series is developed to control the spindle motors in industrial and precision machining. The KDA 3.1-050-3-A0S-W1 will provide 50 Amperes nominal current output to give a stable source of power to complete the spindle.
The KDA 3.1-050-3-A0S-W1 drive uses a three phase AC input power supply that is compatible with industrial voltage supply. It accepts an analog +/-10 Volts velocity reference signal so as to allow precise control of spindle speed. A 9-pin electrical connector is installed in the control terminal to make its installation and safe connection easier. The protection level of IP20 implies safe work in an environment free of liquids and fine dust. It includes an RS-232 C serial interface used in auxiliary communication to compatibles control systems. The KDA 3.1-050-3-A0S-W1 drive has forced air cooling via a dedicated heat sink blower to handle internal temperatures. The blower needs to have a 220 Volts AC power with the frequency of 50 to 60 Hertz. This thermal system operates under continuous load with optimal conditions of operation. It does not feature an auxiliary encoder interface which make it unsuitable where closed loop feedback is required in the operation. The design of the drive emphasizes recovery and control of operations and does not need elaborate configurations of feedback structures. Its DC bus has the voltage rating of 300 Volts in order to facilitate the energy efficient conversion of power and control.
The KDA 3.1-050-3-A0S-W1 drive spindle drive is capable to work reliably in relative humidity conditions less than 95 percent non-condensing. The KDA Spindle Drive component is designed to provide precise spindle speed control and the management of motors clearly.
