Running frequency
When I set the frequency with the externally installed potentiometer, the running frequency displayed on the operation panel is not stable due to noises caused by long wiring distance.
How can I reduce the running frequency variation?

Answer
There are two methods to reduce the running frequency variation.
1. Increase the setting value of Pr.74 (Input filter time constant) to reduce the variation.
When the setting value is too large, the response becomes slow due to change of the potentiometer.
2. Set Pr.268 (Monitor decimal digits selection) not to display the unstable digits. When "0" is set, the integer value is displayed.
