Danfoss · VLT HVAC Drive FC 102
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.
Click steps to track your progress.
Verify the current value of parameter P4-19 (Max Output Frequency) and adjust it upwards if the application genuinely requires a higher frequency.
Check the speed command source (e.g., P3-00 Reference Source) and verify the commanded frequency value from that source.
Review scaling parameters for the reference input (e.g., P6-10, P6-11 for Analog Input 1) to ensure correct conversion to frequency.
Monitor the actual output frequency on the drive display (e.g., P16-01 Motor Frequency) and compare it to the commanded frequency.
Inspect mechanical components for wear or slippage that would necessitate excessive motor speed to achieve desired process output.
