Product Description:
The KDA 3.2-150-3-L00-W1 is a spindle drive from Bosch that is engineered for motor control in industrial applications. It operates with a rated current of 150 A and a continuous current rating of 90 A for providing reliable power, while it utilizes a DC bus voltage of 300 V and features forced cooling to maintain optimal operating conditions.
The KDA 3.2-150-3-L00-W1 drive supports multiple interfaces for speed and position control, including an analog speed command input (±10V), a 16-bit parallel digital speed command and a SERCOS interface for high-performance communication but it comes with only SERCOS interface. It also misses out on auxiliary encoder inputs feature for spindle feedback or additional motor feedback and it uses high-resolution motor feedback for precise position control, with a resolution of up to 1/2000000th of a revolution for C-axis operation. The KDA 3.2 drive’s cooling system gets power from a 220 VAC source and it includes an external heatsink to dissipate heat efficiently, with an airflow of 32 l/s and a pressure of 30 Pa. This spindle drive is designed to function in ambient temperatures ranging from +5°C to +45°C and its protection class is IP10 that offering protection from objects larger than 50 mm in diameter but not against water or finer particles.
The KDA 3.2-150-3-L00-W1 drive has a total weight of 17.4 kg, while it mounts through a mechanical kit that adds further 1.7 kg to the total weight and its blower unit weighs 4.2 kg as well. Its power consumption for control voltage is 1.6 A at 24 V and 160 mA at ±15 V. This unit is designed for easy installation within a control enclosure, with specific mounting frame and cutout is required for proper fitting.
Frequently Asked Questions about KDA 3.2-150-3-L00-W1:
Q: How does high-resolution feedback improve the KDA 3.2-150-3-L00-W1 performance?
A: It enables precise spindle positioning down to 1/2000000th of a revolution. This makes it highly suitable for operations requiring exact C-axis synchronization.
Q: Why is forced cooling used in this spindle drive?
A: Forced cooling ensures stable operation under heavy load conditions. It prevents overheating and extends the lifespan of internal drive components.
Q: What benefit does the external heatsink provide in the KDA 3.2 drive?
A: The external heatsink increases heat dissipation efficiency. It allows the drive to maintain optimal thermal balance during extended operation.
Q: How does SERCOS communication enhance this spindle drive’s usability?
A: The SERCOS provides high-speed, deterministic communication between the drive and controller. This ensures accurate and real-time control for demanding machining processes.
Q: Why does the KDA 3.2-150-3-L00-W1 use a 24 V control supply?
A: The 24 V supply provides stable control voltage separate from the main power. This enhances system reliability during power fluctuations.
