• When P.74=5 and temporary running frequency is at 20Hz, we can detect output impulse wave
between terminal SO and SE as follows:
Note: 1. The multi-function output terminal is SO, When P.40=0 (the default value), it means ‘RUN’. When a
different value is set, the corresponding function will change according to what is shown in the above
table.
2. The internal electrical structures for the multi-function output terminals are the open collector output.
Please refer to Section 3.5.6 and Section 3.5.7 for wiring.
3. When the set value of P.85 is 5 (the default value), the function of the multi-function relay A-B-C is
ALARM. When the value of P.85 is revised, its function changes respectively as the corresponding
function listed in the table above.
4. When setting P.74 to non-zero, SO and FM functions will be invalid.
5. If the FM function is selected, If the users measured by a frequency counter, the value serious
fluctuation, please short SE and 5 terminals.
6. When P.74=1, the output will be 1-fold. The inverter can provide an output between 1 and 400 Hz with a
1% precision. The larger the rate of P.74, the larger the operation frequency, and the poorer the precision.
7. Resistor R must be greater than 3~10KΩ.

• If P.41=5%, a signal (SU) is output when the output frequency enter the 5% region near the target
frequency. For example: the target frequency is set to 60Hz, and P.41=5%, then if the output
frequency is between the 60±60×5%=63Hz and 57Hz region, the SU signal is output.
