Note:
The time deviation in PWM mode is ±12.5%. If pulse PWM is outside of the deviation range the pulse input
is not active.

Setup Pulse Input as Frequency Reference
Set parameter 00-05 to 4 and 03-30 to 0 to use the pulse input terminal PI as the frequency reference source.
Refer to Figure 4.3.5. for details. Next set the pulse input scaling (03-27), enter the pulse input frequency to match
the maximum output frequency. Adjust the pulse input filter time (03-34) in case interference or noise is
encountered.
