Read Timing Operation Selection (Pr.305) - Mitsubishi Electric 800 Series Instruction Manual

NOTE
• Signals X12 to X15 become invalid when "0 to 4" is set in Pr.304.
• Refer to page 22 for a BCD code/binary input example.
• 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, or 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.

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.
