“A” Group: Standard 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).
