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 reference. 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.
The maximum frequency setting
(A004/A204) takes precedence over
frequency upper limit (A061/A261).
