A function for selecting the frequency setting method for the 1st speed frequency operation.
Code No. Function Name
F1002 1st speed frequency
selection
● Reading analog frequency
A function which takes the result of calculation of the 3 channels of control circuit's analog input terminals VIF1, VIF2, VIF3
(frequency command) carried out internally by the inverter as the inverter's command frequency.
The inverter converts the input command of each channel into a frequency by adjusting the bias and gain code. The results are
added or subtracted according to the value of F1002.
A negative result is always regarded as 0. The upper limit of the calculation result is determined using the upper frequency
limit (F1007, F1316 and F1317).
● F1002 = 21: Terminal block stepping function.
This function allows the target frequency to be increased or decreased under ON/OFF status control of the external control
terminals. This function is useful when it is difficult to input an external analog frequency or to set a frequency from the
operation panel.

Function code
F1002=21
· If the first speed frequency selection is set to terminal block stepping (F1002= 21), a frequency setting value can be
entered only from external control input terminals AD2 and AD3 of the inverter host.
Note: The frequency cannot be changed from the operation panel.
· It is a function which takes AD2 terminal as the Up terminal of the set frequency and AD3 terminal the Down terminal
of the set frequency.
Note: When F1002=21 is selected, the AD2 and AD3 terminals set using F1414-F1421 can not be used for the 2nd, 3rd,
or 4th acceleration/deceleration command.
