Motion Control Power Solution – SIEMENS 6SL3255-0VA00-2AA1 | SINAMICS S120
Where This Product Is Used
The SIEMENS 6SL3255-0VA00-2AA1 is the dedicated Operator Panel Interface (OPI) Power Supply for the SINAMICS S120 drive family. It is specified by engineers across demanding industrial environments where reliable, conditioned power to the operator panel interface is critical for uninterrupted drive operation:
- CNC Machine Tools – Powers the operator panel interface on SINUMERIK-integrated S120 drive lines, ensuring stable HMI communication during high-speed machining cycles.
- Automotive Assembly Lines – Sustains OPI power in multi-axis servo systems controlling welding robots, transfer presses, and body-in-white handling equipment.
- Packaging Machinery – Maintains panel interface integrity in high-cycle, 24/7 packaging lines where power interruptions cause costly downtime.
- Printing & Converting Equipment – Provides stable supply voltage to operator interfaces on register-controlled web-fed printing systems.
- Material Handling & Conveyor Systems – Supports OPI modules in distributed S120 booksize drive topologies across long conveyor networks.
- Textile & Fiber Processing – Delivers consistent interface power in tension-controlled winding and unwinding applications.
- Test Benches & Dynamometers – Used in precision torque and speed test rigs requiring stable drive panel communication throughout test sequences.
