Output frequency at maximum limit

Hva betyr 62 ?

The output frequency has reached the maximum value set in parameter 4-19 (Max Output Frequency). This indicates the drive is attempting to run the motor faster than its configured limit, potentially due to incorrect parameter settings or application requirements exceeding the drive's setup. The warning will clear when the output frequency drops below the maximum limit.

• Parameter P4-19 (Max Output Frequency) set lower than the required operating frequency for the application's process speed.
• The commanded frequency reference (e.g., from analog input, fieldbus, keypad) is requesting a speed higher than P4-19.
• Scaling error in the speed reference input (e.g., P6-10 Analog Input 1 High Reference) causing an over-interpretation of the command.
• Mechanical issues (e.g., slipping belt, worn gears) requiring the motor to run at a higher speed to achieve desired process output.
• Motor feedback system (e.g., encoder) misconfigured or faulty, leading to inaccurate speed reporting and over-compensation.

1. 1

   Verify the current value of parameter P4-19 (Max Output Frequency) and adjust it upwards if the application genuinely requires a higher frequency.

2. 2

   Check the speed command source (e.g., P3-00 Reference Source) and verify the commanded frequency value from that source.

3. 3

   Review scaling parameters for the reference input (e.g., P6-10, P6-11 for Analog Input 1) to ensure correct conversion to frequency.

4. 4

   Monitor the actual output frequency on the drive display (e.g., P16-01 Motor Frequency) and compare it to the commanded frequency.

5. 5

   Inspect mechanical components for wear or slippage that would necessitate excessive motor speed to achieve desired process output.
