Inverter Overload

What does 200 mean?

This fault occurs when the drive's internal power components (inverter section) are drawing excessive current for an extended period, indicating an overload on the drive itself. This can lead to overheating and damage to the IGBTs or other power electronics if the condition persists.

• Drive continuously supplying current above its own rated output current, often due to an oversized motor or undersized drive.
• Poor drive cooling due to blocked heat sink fins, high ambient temperature, or failed internal cooling fan.
• Parameter P2-03 (Current Limit) set too high, allowing the drive to exceed its safe operating thermal limits.
• Input voltage (Parameter P1-10) configuration mismatch, causing the drive to operate inefficiently.
• Internal component degradation (e.g., failing IGBTs) causing increased internal losses and heat generation.

Click steps to track your progress.

1. 1

   Monitor the drive's output current (e.g., Display P0-02) and compare it against the drive's rated output current.

2. 2

   Inspect the drive's cooling fan for operation and ensure the heat sink fins are free of dust and debris.

3. 3

   Measure the ambient temperature around the drive and ensure it is within the manufacturer's specified range (e.g., below 50°C).

4. 4

   Verify Parameter P2-03 (Current Limit) is not set above 100% of the drive's rated current unless explicitly required.

5. 5

   Check Parameter P1-10 (Rated Input Voltage) to ensure it matches the actual supply voltage.
