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. The upper limit must
not exceed the rating of the motor or
capability of the machinery.
