Product Description:
The KDA 3.1-150-3-DYS-U1 lists rated current at 150A which delivers steady drive output for extended spindle use, supporting correct fuse and DC link rating in the cabinet design. With 3 axes, this spindle drive also consolidates three spindle channels into one module and reduces overall cabinet part count for multi-spindle systems. With mains supply rated at 3 x 400 V AC, this advanced unit connects directly to typical industrial networks, which eases wiring tasks and avoids extra transformer work during worldwide deployment.
Its control section runs on 24 V DC, supplying energy to logic circuits and auxiliaries that bring uniformity to sensor and interlock connections across the cabinet. By applying internal air cooling, heat from the power electronics is managed inside the device, reducing dependence on separate cooling hardware in standard cabinet arrangements. This 50/60 Hz frequency is supported to allow operation on standard mains frequencies and avoids frequency conversion when deploying the unit across different regions. Rated power of maximum 11 kW per axis defines continuous mechanical output and guides motor selection and inverter current limits for each spindle channel.
Protection rating of IP20 is assigned which designates open-style cabinet mounting and hence demands a sealed control enclosure with filtered intake to protect electronics. Feedback resolver, encoder support accepts both rugged analog rotors sensing and high-resolution encoder inputs. The module uses SERCOS bus interface that allows deterministic digital communication and supports synchronization with fast speed cyclic transfers for coordinated motion. With mass of 30 kgand control cabinet mounting, this centralizes power and control hardware. This simplifies service access and cable routing inside a single enclosure of the module KDA 3.1-150-3-DYS-U1.
Frequently Asked Questions about KDA 3.1-150-3-DYS-U1:
Q: What does the continuous current specification mean for KDA 3.1-150-3-DYS-U1?
A: The continuous current 150 A for KDA 3.1-150-3-DYS-U1 defines the sustained current the module can supply under rated cooling.
Q: Why does control voltage matter for KDA 3.1-150-3-DYS-U1 and how is it used?
A: The control voltage 24 V DC for the controller powers control logic, interlocks and auxiliary relays which permits use of standard industrial sensors and safety circuits.
Q: How does the number of axes affect system architecture for KDA 3.1-150-3-DYS-U1?
A: The three number of axes for the drive enables consolidation of three spindle channels into a single module which reduces overall module count and simplifies synchronization wiring.
Q: What mains voltage be considered when installing KDA 3.1-150-3-DYS-U1 drive?
A: Mains voltage 3 x 400 V AC for this module determines incoming feed design, earthing strategy, and upstream protection devices.
Q: How does the internal cooling method influence enclosure planning for KDA 3.1-150-3-DYS-U1?
A: The device uses an internal air cooling that channels forced air through the module’s heatsink which requires cabinet ventilation and planned airflow paths to remove heat effectively.
