Product Description:
The Bosch Rexroth Indramat manufactured KDA 3.2-050-3-AYI-W1 Spindle Drive comes with a current rating of 50 A, supporting efficient power supply for medium to heavy-duty spindle operations. This drive is designed to function optimally at a DC bus voltage of 300 V, maintaining consistent internal power distribution during operation.
The speed setpoint of this spindle drive is regulated through an analogue ±10 V input in order to make fine-tuned and instant speed adjustments. The speed command input further accommodates the analog ±10 V A signal to ensure precise performance under different conditions of loads. The cooling of the KDA 3.2-050-3-AYI-W1 drive is provided by forced convection through a heatsink fan, which keeps internal temperatures within the operating range even during intense use. This heatsink’s blower utilizes an AC supply source of 220 V at 50–60 Hz, which is kept separate from the main power source, to provide focused and reliable cooling. This drive is equipped with an incremental encoder output as part of its auxiliary interface to offer feedback signals that are necessary for motion control systems. It also has auxiliary and synchronous encoder inputs and supports flexible encoder configurations for primary and secondary feedback integration.
This spindle drive can perform at a maximum ambient temperature of +55°C, which allows it to be used in normal industrial environments. It can endure a broad temperature range of -30°C to +85°C when stored and transported, safeguarding in-transit components under different logistic conditions. This drive is rated with an IP 10 electrical protection category that allows installation in clean and enclosed locations since it is not dust or water protected. For elevation needs, the KDA 3.2-050-3-AYI-W1 drive can be mounted at heights of up to 1000 meters above sea level with no loss of performance, satisfying altitude requirements.
Frequently Asked Questions about KDA 3.2-050-3-AYI-W1:
Q: Why does the KDA 3.2-050-3-AYI-W1 use a separate AC supply for the heatsink blower?
A: This ensures continuous fan operation, independent of the main DC bus voltage. It improves thermal regulation during system idle or low-load conditions.
Q: How does the ±10 V analog speed input benefit the control system?
A: It provides a linear speed response, allowing precise analog control in automation setups. This simplifies integration with analog-based PLC systems.
Q: What is the role of the incremental encoder output in this spindle drive?
A: It delivers real-time feedback to the control system for motion tracking. This supports synchronized operations in multi-axis applications.
Q: Can KDA 3.2-050-3-AYI-W1 operate in dusty or damp environments?
A: No, it has an IP 10 protection rating. It must be installed inside sealed electrical cabinets or clean enclosures.
Q: Why is forced cooling preferred in KDA 3.2-050-3-AYI-W1 instead of passive cooling?
A: Forced cooling actively removes heat, enabling higher current operation without thermal overload. This is essential in high-duty cycles or enclosed spaces.
