Product Description:
The model KDA 2.1-150-3-LP0-W1 is a digitally controlled spindle drive designed for precision drive applications. It supports high resolution position control and offers flexible feedback configurations. It ensures stable drive operations with consistent speed regulation. This unit operates efficiently under varying loads and ambient conditions.
This Bosch Rexroth KDA 2.1-150-3-LP0-W1 main spindle drive uses a microcomputer to manage drive control, diagnostics and monitoring functions. It ensures high resolution rotor position detection throughout the full speed range. The speed control range extends from 0.0005 rpm to high speeds that enables accurate C-axis functionality and exact spindle positioning. The control system supports SERCOS interface for the speed command value. The internal position control is achieved through high resolution motor feedback or auxiliary spindle feedback. The drive is built to handle continuous current up to 90 A that offers robust operation under industrial loads. It incorporates forced cooling to maintain stable thermal conditions during prolonged use. The heatsink blower is powered by an external 220V AC supply at 50 60 Hz. Its compatibility with 2AD asynchronous motors and 1MB spindle motors ensures broad application flexibility.
An auxiliary encoder input is available in this KDA 2.1-150-3-LP0-W1 main spindle drive for spindle or second motor feedback. The drive accepts a + 24 V load voltage and draws 1.6 A during operation. It is designed to function reliably in ambient temperatures up to 55 °C with reduced nominal performance beyond standard conditions. The unit is suitable for installations up to 1000 meters above sea level. It supports a humidity classification marked “F” that ensures dependable operation in controlled moisture environments. These features together ensure precise control and compatibility with demanding motion control systems.
