Multi-step Speed Reference 0 Exceeds Upper Limit

What does 015 mean?

This warning occurs if the frequency set for Multi-step speed reference 0 (A020) or the output frequency setting (F001) is higher than the configured frequency upper limit (A061). This creates a logical conflict in the drive's speed constraints, as a programmed speed is above the allowed maximum.

• A020 (Multi-step Speed Ref 0) was manually configured to a value exceeding A061 (Frequency Upper Limit).
• A061 (Frequency Upper Limit) was inadvertently lowered to a value below the intended operating point of A020.
• An external frequency command (driving F001) is scaled incorrectly or experiencing noise, causing it to momentarily exceed A061.
• Restoration of an incompatible parameter set where A020 was saved with a higher value than the current A061.

Click steps to track your progress.

1. 1

   Access parameter A020 (Multi-step Speed Reference 0) and A061 (Frequency Upper Limit). Compare their values.

2. 2

   Adjust A020 (Multi-step Speed Reference 0) to be less than or equal to A061 (Frequency Upper Limit).

3. 3

   Alternatively, if the application requires A020 to be higher, increase A061 (Frequency Upper Limit) to be equal to or greater than A020, ensuring A061 does not exceed A004 (Inverter Max Frequency).

4. 4

   If F001 (Output Frequency) is causing the issue, verify the scaling of any external analog frequency references (e.g., 0-10VDC input to terminals X2-1/X2-2) and ensure the source is stable and within expected range.

5. 5

   Save the parameter changes and power cycle the drive to confirm the settings are active.
