Frequency Calculation Function
When “13: Calculation result” is set to Frequency Reference Selection (F01/C30), two frequency refer-
ences are calculated.

Note 1. The same setting can be made in E131/E132.
Note 2. If the calculation results exceed 1st Maximum Output Frequency (F03)/2nd Maximum Output Frequency
(A01), the limit is set at the maximum frequency. Similarly, if the calculation results are below 0.0 Hz, the
limit is set at 0.0 Hz.

Frequency Addition Function
Use this function to add or subtract the value set at Frequency Addition Amount (E134) to or from the
selected frequency reference.
If “161: ADD” is not allocated to the multifunction input terminal, or if the ADD terminal is ON, add or
subtract E134. If the ADD terminal is turned OFF, the addition or subtraction of Frequency Addition
Amount (E134) is canceled, and the inverter returns to the status of the selected frequency reference.
