DRV-19 Start Freq
Set the lower limit value for speed unit parameters that are expressed in Hz or
rpm. If an input frequency is lower than the start frequency, the parameter
value will be 0.00.

frequencies from within the upper and lower limits.
This restriction also applies when you in input a frequency reference using the
