Application-Specific FAQ
Q: Can the 6SL3040-0MA00-0AA0 control both servo and vector (induction motor) drives simultaneously?
A: Yes. The CU320-2 DP supports mixed drive object configurations — servo control (DSC) and vector control can coexist on the same control unit, each assigned to separate Motor Modules.
Q: What is the maximum number of axes this control unit can manage?
A: Up to 6 drive objects (axes) per CU320-2 DP, depending on firmware version and computational load. For higher axis counts, multiple CU320-2 units can be networked via PROFIBUS.
Q: Is a CompactFlash card included?
A: The CompactFlash card (6SL3054-0EG00-1BA0) is ordered separately. It is required for firmware storage and parameter backup — do not operate the CU320-2 without it.
Q: Can this unit replace an older CU320 (6SL3040-0MA00-0AA0 vs. 6SL3040-0LA00-0AA0)?
A: The CU320-2 DP is the successor to the original CU320. It is backward-compatible in most S120 booksize configurations but requires firmware ≥ V4.3. Verify your Motor Module firmware versions before replacement.
Q: Does Konmask.com provide technical support for commissioning?
A: Yes. Our engineering team can assist with PROFIBUS network configuration, DRIVE-CLiQ topology setup, and Startdrive parameterization. Contact us at [email protected].
