Frequency-related Functions
Frequency Limits – Upper and lower
limits can be imposed on the inverter
output frequency. These limits will apply
regardless of the source of the speed refer-
ence. You can configure the lower
frequency limit to be greater than zero as
shown in the graph to the right. The upper
limit must not exceed the rating of the
motor or capability of the machinery.
