Description of Functions
F1422
Reference frequency for pulse train input
This function is used to set the input frequency corresponding to standard pulse train in order to convert output frequency
when setting the output frequency through pulse train input (F1002 = 25).
Code No.

If F1002 = 25, then the pulse from the pulse input terminals (A +, A-) can be used as a command to set the target
frequency of 1st speed frequency.
When pulse train input is selected, the following functions are inactive.
· F8108 (PG pulse multiplication value):
Regardless of the value, considered as × 1.
· F8109 (PG output formation selection):
Regardless of the value, input of standard PG terminal.
Reference frequency for pulse train input (F1422) is a frequency within the
base
frequency (F1006). Therefore, the
inverter output frequency is calculated with the following formula:
Note 1: Because the pulse train input and PG input terminal are in common use, speed is displayed as inactive in pulse train
input selection. (The correct value is not displayed)
Note 2: Please input pulse train only into the A +, A- terminals.
Note 3: 100,000Hz is the limit of pulse train input frequency.
Note 4: The conversion error will be generated in the conversion of pulse train frequency and output frequency.
In order to reduce the conversion error, please increase the pulse train input frequency.
