New Spare Part

What does 250 mean?

This alarm indicates that a major power-related component, specifically the power section or switch mode power supply, within the frequency converter has been replaced. It serves as a service notification rather than an operational fault, confirming a hardware change. The drive should function normally after this alarm, assuming proper installation of the new part.

• The power card (or power module) of the frequency converter has recently been replaced as part of a service action.
• The internal Switch Mode Power Supply (SMPS) unit has been replaced.
• A drive hardware configuration change was detected upon power-up after maintenance.
• This is an informational alarm, not an indication of a new malfunction.
• An incompatible spare part was installed (less likely if the unit powers on and operates).
