Product Description:
The model KDA 3.1-100-3-LPD-W1 is a precision main spindle drive designed for reliable performance in industrial applications. It delivers stable control and high operational efficiency. The unit is built with robust specifications and adheres to strict operational safety standards for demanding machine environments.
This KDA 3.1-100-3-LPD-W1 Main Spindle Drive operates with a continuous current of 90 A and requires a control voltage consumption of + 24 V load voltage at 1.4 A. It is designed to operate with a DC bus voltage of 300 V. The unit features a blower unit (LE4) with a weight of 4.2 kg. The model’s ambient operating conditions allow a permissible temperature range of + 5 °C to + 45 °C with nominal data and a maximum temperature of + 55 °C under reduced nominal data. The installation is allowed at elevations up to 1000 m above sea level that ensures stable performance in varied environments. The unit is classified under protection category IP 10 which requires controlled installation conditions. The spindle drive supports speed command values via the SERCOS interface. It is recommended to confirm absence of voltage with certified testing equipment before handling. The spindle drive has been engineered with reliable safety and efficiency in mind.
The KDA 3.1-100-3-LPD-W1 main spindle drive from Bosch offers efficient power handling and stable spindle control. It is essential to mount the drive in a vertical position with grounding bolts positioned at the top. During handling, appropriate lifting tools should be used to avoid injury or equipment damage. The unit includes diagnostic indicators in the form of LED lights that provide real time operational status feedback. These indicators must be monitored regularly for early identification of faults or abnormalities.
Frequently Asked Questions about KDA 3.1-100-3-LPD-W1:
Q: How does the KDA 3.1-100-3-LPD-W1 manage reliable status diagnostics during continuous machine operation?
A: The unit integrates LED diagnostic indicators that provide real-time operational feedback. These should be actively monitored to detect early-stage faults before they escalate in critical environments.
Q: What environmental and layout constraints should I consider when installing the KDA 3.1-100-3-LPD-W1 spindle drive?
A: It supports vertical mounting only, with grounding bolts placed at the top for safe configuration. Installation beyond 1000 meters elevation or outside rated temperatures may affect nominal performance.
Q: How does the KDA 3.1-100-3-LPD-W1 spindle drive ensure control system compatibility in closed-loop automation?
A: Speed commands are supported through the SERCOS interface, enabling seamless integration into modern drive architectures. This ensures synchronized control across networked motion systems.
Q: What electrical safety steps should be taken before servicing the KDA 3.1-100-3-LPD-W1 main spindle drive?
A: The certified voltage testing equipment must confirm total power absence before access. This procedure is essential for safe handling due to the unit’s internal DC bus voltage configuration.
Q: How does the blower unit in the KDA 3.1-100-3-LPD-W1 support thermal stability during intensive spindle cycles?
A: The integrated LE4 blower module promotes continuous airflow, keeping internal components within rated thermal margins. It plays a key role in maintaining operational consistency under sustained load.
