Product Description:
The Bosch’s spindle drive KDA 3.2-050-3-A00-W1-220 works with forced cooling through an exclusive heatsink ventilator blower that manages the internal heat loss. Its air flow is rated at 32 liters/s and it produces a pressure of 30 pascals at the heatsink, while this blower functions on 220 VAC supply at 50 or 60 Hz frequency.
The KDA 3.2-050-3-A00-W1-220 drive operates on a DC bus voltage of 300 V and its supported output steady current is specified at 50 A. It is designed for a motor power range of 3 to 7.5 kW and it functions with analog speed input command that is accessible through a 9-pin X4 connector. The drive’s control signals and I/O interfaces are located at the 37-pin X2 connector. Its feedback connections are supported through a 15-pin X3 terminal point and it does not include an auxiliary encoder input while the control bus voltage is connected via terminal X8. This KDA 3.2-050 drive consumes 1.2 A on the +24 V control voltage and 160 mA on the ±15 V. It includes a blower bus connection through X13, X14a and X14b. Its installation orientation is strictly vertical with grounding bolts located above the frame and parameters are stored by the provided AS3 programming module. The KDA 3.2-050 drive connects motor via terminals A1, A2 and A3.
The KDA 3.2-050-3-A00-W1-220 drive includes an onboard microcomputer for diagnostics and control. Its position monitoring uses high-resolution rotor feedback system and it supports C-axis operation along with spindle positioning. The drive requires a mounting space of 185 mm width, 390 mm height and 373 mm depth. It comes with a protection category of IP10 per DIN 40 050 and requires proper grounding through a 10 mm² cable.
Frequently Asked Questions about KDA 3.2-050-3-A00-W1-220:
Q: How does the heatsink blower improve thermal management in the KDA 3.2-050-3-A00-W1-220?
A: The forced cooling blower ensures efficient heat dissipation, maintaining thermal stability during continuous operation. This prevents thermal overload and extends drive lifespan.
Q: Why does the KDA 3.2-050-3-A00-W1-220 use a 9-pin X4 connector for analog speed input?
A: The 9-pin X4 connector offers isolated analog signal access for precise speed control. It helps reduce electrical noise and signal degradation.
Q: What role does the high-resolution rotor feedback system play in the KDA 3.2-050-3-A00-W1-220 drive?
A: It enables accurate position monitoring for spindle and C-axis functions. This feedback enhances motion accuracy and repeatability in complex operations.
Q: Why is a 10 mm² grounding cable necessary for the KDA 3.2-050-3-A00-W1-220?
A: Proper grounding with a 10 mm² cable ensures safe dissipation of fault currents. This also helps meet IP10 safety compliance standards.
Q: What is the advantage of the vertical mounting orientation in the KDA 3.2-050-3-A00-W1-220?
A: Vertical orientation supports optimal airflow for cooling and ensures safe operation. It also aligns with the drive’s mechanical design for load-bearing efficiency.
