NOTE
• Signals X12 to X15 become invalid when 0 to 4 are set in Pr.304.
• Refer to
page 19
• If 0 to 5 V (0 to 10 V) is input at the inverter terminal 1 from the external potentiometer with the FR-A8AX installed, the
inverter operates at the frequency obtained by adding the FR-A8AX BCD code input and the compensation input from
terminal 1 only when "2, 3, 12, 13" is set in Pr.304.
For example, when switching the inputs to perform manual operation with potentiometer input or automatic operation
with BCD code input, set the BCD code input to "0" under manual operation.

PARAMETER
for a BCD code/binary input example.
The set frequency data entered from the digital signal input terminals (X0 to X15) is always imported
independently of whether the DY signal is ON or OFF.
The set frequency data entered from the digital signal input terminals (X0 to X15) is imported only
when the DY signal is ON. The set frequency data is not imported when the DY signal is OFF.
Therefore, even if the input status of the X0 to X15 signal changes, the set frequency data before the
DY signal is turned OFF is valid.
The set frequency data entered from the digital signal input terminals (X0 to X15) is always imported
independently of whether the DY signal is ON or OFF.
The filter absorbs subtle timing differences of digital signal acquisition.
