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