Trim Control Level
The trim control level is valid when the trim control increase command (setting: 45) or trim control
decrease command (setting: 46) is set for a multi-function input (H1-01 to H1-06).
If the trim control increase command is ON when a frequency reference is input on the analog input,
the trim control level will be added to the analog frequency reference and then that sum will be
output as the output frequency. If the trim control decrease command is ON, the frequency reference
will be decreased by the trim control level.
Set the trim control level as a percentage of the maximum output frequency.
If the frequency reference minus the trim control level is less than zero, the output frequency will be
zero.
