Product Description:
The Main Spindle Drive KDA 3.2-100-3-LYS-W1 is developed by Bosch Rexroth. It operates with a nominal DC link voltage of 300 VDC. The rated output current of the drive is 100 A. It supplies a continuous output current of 70 A for stable operation. The unit delivers a 24V auxiliary current rated at 1.4 A. It also includes a ±15V measurement current output of 160 mA.
This KDA 3.2-100-3-LYS-W1 spindle drive is designed for vertical setup only. The grounding points are positioned on the top panel. The enclosure height measures approximately 373 mm. The body width is 160 mm without an air duct and 185 mm when it is attached. The base drive unit weighs 17.1 kg. The cooling blower contributes an additional 4.2 kg. The system is intended for installation at elevations up to 1000 meters with no derating. The output performance of the KDA 3.2-100-3-LYS-W1 spindle drive must be adjusted accordingly above this height. It adheres to DIN 40 040 Class F environmental category. The drive supports up to 70% relative humidity under non-condensing conditions. The enclosure rating is classified as IP10 as per DIN 40 050. This protection class applies only when the unit is housed within a suitable control cabinet.
The cooling of the KDA 3.2-100-3-LYS-W1 spindle drive is achieved through forced ventilation with an external blower mounted to the heatsink. The airflow requirement is 32 liters per second. The air velocity at the blower should remain between 3 and 4 meters per second. The maximum backpressure at the heatsink should not exceed 30 Pa. The internal heat loss varies based on the power demand. The recommended ambient operating range is between +5°C and +45°C. The storage conditions support a range from -30°C to +85°C with proper derating.
Frequently Asked Questions about KDA 3.2-100-3-LYS-W1:
Q: What challenges should be considered when selecting a location for the Bosch Rexroth KDA 3.2-100-3-LYS-W1 spindle drive?
A: When installing the Bosch Rexroth KDA 3.2-100-3-LYS-W1 spindle drive, its vertical mounting requirement and proximity to adequate ventilation must be considered. The unit’s cooling system and airflow specifications need to be accounted for to ensure effective heat dissipation and maintain consistent operation.
Q: How does the Bosch Rexroth KDA 3.2-100-3-LYS-W1 spindle drive behave during peak load conditions?
A: During peak load conditions, the Bosch Rexroth KDA 3.2-100-3-LYS-W1 spindle drive draws its rated current of 100 A, with a continuous output current of 70 A to maintain stable operation. Proper current management and monitoring are essential to ensure the system operates within safe limits during maximum demand periods.
Q: How does the Bosch Rexroth KDA 3.2-100-3-LYS-W1 spindle drive manage heat generation during long-term operation?
A: The Bosch Rexroth KDA 3.2-100-3-LYS-W1 spindle drive incorporates forced ventilation through an external blower, designed to handle internal heat loss based on power demand. Effective thermal management relies on maintaining proper airflow and preventing excessive backpressure to avoid overheating during continuous operation.
Q: What impact does the Bosch Rexroth KDA 3.2-100-3-LYS-W1 spindle drive’s weight have on installation?
A: The Bosch Rexroth KDA 3.2-100-3-LYS-W1 spindle drive’s base weight of 17.1 kg and an additional 4.2 kg for the cooling blower requires secure mounting and careful consideration of load-bearing capacity. The system's total weight impacts the structural integrity and stability of the mounting platform during operation.
Q: How does the Bosch Rexroth KDA 3.2-100-3-LYS-W1 spindle drive ensure stable operation with a variable current draw?
A: The Bosch Rexroth KDA 3.2-100-3-LYS-W1 spindle drive’s ability to adjust current draw based on load ensures stable operation. The drive draws a continuous 70 A under standard conditions and adjusts dynamically during peak loads to match the power demands without compromising system stability.
