Product Description:
The KDA 2.1-050-3-LPD-W1 is a main spindle drive made by Bosch Rexroth and is designed for precise motion control in industrial automation. It is part of Series 2 and has Design 1. The drive is made to work reliably in tough grinding situations. The AC main spindle drive supports continuous performance by keeping things cool and integrating reliable electrical controls.
Forced cooling is effective for steady temperature control because the heatsink fan operates with a 220 VAC power source. With a maximum current of 50 A, the KDA 2.1-050-3-LPD-W1 main spindle drive has a DC bus voltage of 300 V. It has an extra encoder input that can handle feedback from the spindle or a second motor, giving you more options for how it works. There is a digital 16-bit parallel position command value interface that lets you control movements precisely. A SERCOS interface allows for the transmission of speed command numbers to the drive. The drive is made to be very stiff, which prevents changes in performance over a wide speed range. According to DIN 40 050, the ingress protection rating is IP10. The working temperature range is from 0°C to +45°C, which ensures that the device works reliably within safe temperature ranges. According to DIN 40 040, the climatic category is Class F, which also indicates the object's ability to retain heat and insulate electricity.
The KDA 2.1-050-3-LPD-W1 main spindle drive can be installed up to 1000 m above ground, which means it can be used reliably at normal operating heights. Adding extra interfaces and communication methods to the main ones makes sure that connections with drive controllers stay stable. The product has cooling and feedback systems that work together to keep the performance consistent.
Frequently Asked Questions about KDA 2.1-050-3-LPD-W1:
Q: Why does KDA 2.1-050-3-LPD-W1 have forced cooling?
A: The drive includes forced cooling by a heatsink blower that prevents thermal overload. It ensures stable operation and consistent output under maximum current loads with a 220 VAC supply.
Q: Why does KDA 2.1-050-3-LPD-W1 support SERCOS interface speed?
A: The SERCOS interface provides a digital speed command that ensures accurate spindle control. It delivers stable communication with machine controllers that improves synchronization and motion accuracy.
Q: How does KDA 2.1-050-3-LPD-W1 ensure continuous power delivery?
A: The spindle drive supports continuous power delivery that maintains stable torque. It covers an extensive speed range that allows reliable control across varying machining requirements and conditions.
Q: Does KDA 2.1-050-3-LPD-W1 allow auxiliary encoder inputs?
A: The drive allows auxiliary encoder input that enables additional feedback. It supports spindle or second motor monitoring that ensures precision and operational flexibility during operation.
Q: Why do KDA 2.1-050-3-LPD-W1 drives use a 300 V DC bus?
A: The 300 V DC bus ensures efficient energy transfer. It stabilizes the voltage supply to power electronics that reduces fluctuations and enhances drive control accuracy in spindle operation.
